AE industrial catalogue of telephone-type relays and stepping switches with specs.
utomatic Electric Company pioneered the use of reliable telephone- type relays in industrial applications. Today, the bulk of automatically operated machines use relays and switches of a type developed by A.E. Our diverse family of industrial controls includes seven principal classes of relays in many varieties of coil and spring pile-up combinations, with wide latitude in operate and release times, and for either a.c. or d.c. operation. Further, we manufacture rotary stepping switches, such as the Type 44 and the Type 45, along with the versatile, cam-operated OCS Stepping Relay (these are described in Circular 1698 and Catalog 4071). A.E. also specializes in the hermetic sealing of individual relays and switches, or combinations of these to form industrial control ‘‘package units.” In short, Automatic Electric Company has the experience, reputation, manufacturing facilities, research staff, and down-to-earth, ‘‘know-how”’ to help solve your knottiest control problem. practical CLASS B RELAY Finest telephone-type relay available is the famous Class B all-purpose “workhorse.” Characterized by dependable operation and long life, it weighs 8 to 14 oz., and measures 4-1/8” x 2-1/4” x 1-1/32”. Mechanical life expectancy — 400 million operations. CLASS E RELAY Intermediate size Class E relay reduces the best of the Class B features to a minimum of space and weight. Life of 200 million operations, and upwards, is available from this relay. SERIES SQPC RELAY For Printed Circuits. Series SOPC is designed for direct insertion into printed circuit boards. This space- and weightsaver is used in aircraft and similar appli- cations. Only 1-3/4” x weight— 2-1/2 to 3 oz. 1-3/4" x 1”; Mechanical life expectancy— 120 million operations. CHOOSE FROM CLASS THIS WIDE B FOR RANGE OUTSTANDING OF TYPES ENDURANCE AND DEPENDABILITY When extremely long service and reliable operation are demanded, this relay meets the requirements. Life often exceeds 400 million operations. Ideal for computers, fire control, pulsing or switching functions. Choose the Class B relay for the most exacting high-speed or marginal oper- ations. For AC or DC operation. CLASS E A HUSKY NEW SPACE-SAVER Introducing a new telephone-type relay, designed for dependable long-life industrial service . . . where weight and space considerations determine size limitations. Based on the rugged Class B design, this is a universal relay, engineered for a variety of uses demanding compact size coupled with our usual high standard of reliability. CLASS A WHEN FIRST COST IS IMPORTANT When you want relays that will hold down costs, yet provide dependable operation and long-life, specify the Automatic Electric Class A relay. This is the original “telephone-type’” relay. A wide variety of coils, contacts, contact spring arrangements and mounting facilities makes this truly the “all-purpose” relay. CLASS C WHERE SIZE LIMITS RELAY SELECTION This compact relay combines unusual dependability and surprisingly long service life in a space about half of the size of the average relay of equal rating. Use it where space and weight saving are important. Has the same basic design characteristics as the Class B relay. Can be used for high-speed or delayed operation. CLASS S$ FOR EXACTING MINIATURE APPLICATIONS Specify this relay for aircraft use, where a small, light relay is required, resistant to shock and vibration. Will meet most standard 10G vibration tests. Can be relied upon for fast pulse response because of its small mass and slight self-inductance. Voltages shown are nominal. Series SOPC available for printed circuits. CLASS Z FOR MAXIMUM TIMING WITH REDUCED SIZE Similar to Class A relay, but smaller and does not provide the same sensitivity and range of time delay characteristics or the exceptionally large number of contact springs. Choose Class Z relays where a small, light relay is needed but long life or time delay is of greater importance than extremely small size. CLASS F FOR A.C. OPERATION For use when the number of relays doesn’t justify a rectifier, and when operate and release time delays are not a factor. An inexpensive rectifier can be used with any of the above d.c. relays when operate and release timing is required. The Class F relay features low power consumption, while the Class B has superior life expectancy and handles heavier contact loads. POLARIZED WHEN SENSITIVITY TO MAGNITUDE AND DIRECTION OF CURRENT ARE REQUIRED Series PHD and PLD are available for either “2-position” or “3-position” operation. Series PTW provides only “2-position” operation. “2-position” relays “stick” operated until current is reversed; “3-position” operation provides a neutral position for the armature when no current is flowing. SPECIAL PURPOSE TO SUIT YOUR APPLICATION We can usually make assemblies of Automatic Electric relays with modifications to suit your special applications. The Class E Video relay, illustrated here, is an example. Others are designed for power applications, electro-mechanical interlocking, marginal operation, mechanical locking, micrometer adjusting, and the simultaneous closing of up to 35 circuits (BAR relay). ‘ | SERIES BQA BSO BSR BSA BFA BMS OPERATING TIME, SECONDS 0.002-0.030 0.040-0.120 0.004-0.035 0.020-0.055 0.010-0.025 0.010-0.030 RELEASE TIME, SECONDS 0.005-0.050 0.025-0.350 0.035-0.600 0.035-0.600 0.008-0.020 0.015-0.050 MAXIMUM COIL VOLTAGE 250 de 135 de 135 de 250 de 230 ac 250 de MAXIMUM NO.

In military applications, use them in equipment that will be subjected to high humidity, fungi, salt spray, sand, or varying air pressure. In all of these hermetically sealed tinuously uniform applications, Automatic Electric relays and switches assure con- performance, for they operate in an “ideal” atmosphere. In this atmosphere the relay or switch is positively protected from all harmful effects. The atmosphere is actually a part of the relay or switch and it is sealed into a metal container by the latest methods. In the hermetic sealing process, the relay or switch is mounted firmly in a combination base and bracket to which is attached an evacuation tube. A glass terminal disk is hermetically sealed to this base, and the relay or switch is wired and soldered to it. Then a metal housing is fitted over this partial assembly. The edge of the housing is hydraulically crimped over the base, and the seam soldered to form a tight hermetic seal. Then the assembly is attached to a high vacuum pump and is evacuated to remove moisture and gases. While under vacuum, the enclosure is tested for leaks. Then it is flushed with dry nitrogen, and again evacuated. Finally, the enclosure is filled with dry gas (usually nitrogen) to a pressure of at least one atmosphere, and the evacuation tube is closed and sealed. The completed assembly is painted for additional protection against corrosion, and is labeled in compliance with the Armed Service or other specifications. The result is a hermetically sealed relay or switch that satisfies the requirements of temperature, mersion tests as described rently in force. humidity, and im- in service specifications cur- Enclosures are available in a variety of sizes and shapes to meet virtually any engineering requirements. Many types of relays and switches can be sealed in these enclosures. Some hermetic enclosure will exactly satisfy the needs of your particular problem. For specific information on the dimensions of these enclosures and the types of relays and switches that can be sealed in them write for Catalog 4083. l J PROTECTIVE ENCLOSURES (NOT SEALED) HERMETICALLY The same type of enclosure as is employed for hermetic sealing can be used as a slip-on cover for dust protection. In such a case the relay or rotary stepping switch is mounted and wired to the base in the same way as for hermetic sealing. The cover flange is left uncrimped and serves as a pressure fit between base and cover. A self-tapping screw is usually used to secure the cover in place. Most of the hermetic-type enclosures used for relays and switches are available for this special form of protection. The Class S relay with not to exceed three springs per pile-up with Code No. 0-20 ga. contacts is available in a clear plastic case with octal plug mounting (shown at right, center). For specific information, and dimensions of protective enclosures, write for Catalog 4083. SIZES, SHAPES, The Relay and Rotary Stepping Switch contacts listed here are applicable for almost any control purpose. Many can be supplied as twin contacts, that is, two contacts mounted on separate arms of each contact spring; the circuit is thus completed tact if the other contact is held open OF RATINGS through one conby dust or grit. Twin contacts are used also to increase current-carrying capacity. A pair of twin contacts, properly adjusted, RELAY have almost twice contact, but contacts for breaking CONTACTS the carrying capacity usually do not provide or making of a single higher rating of circuits. Contact rating is affected by relay characteristics; size, shape and material of spring; and contact assembly. All moderately heavy to heavy inductive load circuits should have suitable spark suppression. CONTACTS *N.1.—Non-inductive. How to Order AE Relays For fastest service, order relays from among the Standard Assemblies on the following pages. The component parts for these are stocked and, therefore, readily available. When the Standard Assemblies do not meet your requirements, order a Custom Assembly. A 100-page catalog 6 “Relays and Switches for Industrial Control” is available to help you in ordering the exact relay for your application. If you need technical advice, contact the Automatic Electric representative nearest you for prompt, courteous assistance. A list of Automatic Electric district and branch offices is on the back cover. STANDARD Code ET RRS 0-18 Gauge, The following relays, with Form C (‘‘break-make’’) contact assemblies, may be used wherever ‘‘make’’, "break", or ‘“‘break-make’’ combinations are required. Resistances and voltages in ihese tables will give reliable operation with minimum power consumption. For economy, use 800 to 1000-ohm coils on 24 volts, d.c.; 1300 to 2000-ohm coils on 48 volts, d.c.; 2500 to 4000-ohm coils on 115 volts, 1C BQA ASSEMBLIES, Twin RELAYS, D.C. Contacts d.c.
