YA RELAY NONLATCH AC COIL 4 PDT, 5 AMP – ENGINEERING DATA SHEET

Category: Electronics, Esterline Power Systems Leach International, Relays

Overview

The engineering datasheet presents the LEACH® Series W Relay, a nonlatching 4-pole double-throw (4 PDT) relay with a 5 Amp capacity, designed for demanding military specifications under MIL-PRF-83536. It comes with an AC coil rated for use at 115 VAC and 400 Hz, optimized for resistive, inductive, motor, and lamp loads. A notable feature is the all welded construction, ensuring robust and reliable operation.

Principle Technical Characteristics

This relay is noted for its welded construction, Polarized PDT contact arrangement, and its capacity to handle varying types of electrical loads. The contacts are rated for low-level applications at 28 Vdc and for higher power requirements at 115/200 Vac; 400 Hz. The maximum weight specified for the relay is 30 grams, with case dimensions provided in millimeters. The product is tailored for applications that may require specialized models which are available upon request.

Applications

The datasheet underscores the relay’s hermetically sealed nature which guarantees corrosion resistance, and it is housed within a metal can. An applicable socket is identified as part number SO-1066-10385/10386, suggesting compatibility with existing hardware or systems.

Contact Electrical Characteristics

Varied ratings are given for different load types when operated at 28 Vdc or 115/200 Vac at 400 Hz. The relay can support resistive loads up to 5 Amps, inductive loads up to 3 Amps, motor and lamp loads up to 2 Amps, with overload capacity rated at 20 Amps and rupture capacity at 25 Amps. The low-level rating and time-current characteristics are also specified, though additional details on these are presumably provided later in the datasheet.
