Mid-Range Relays, 2 Form C, DPDT, 2 C/O, Coil Suppression Diode, Gold Terminal Plating, 5 A, 28 VDC Coil Voltage, CII FCB-205 Series The M83536/2-024M is a hermetically sealed electromechanical power relay built to comply with the MIL-PRF-83536 military specification family, a standard governing high-reliability relays intended for use in demanding military, aerospace, and defense electronic systems. Devices manufactured under this specification series are designed to meet stringent requirements for mechanical ruggedness, electrical performance consistency, and long-term reliability under the extreme vibration, shock, temperature cycling, and altitude conditions typically encountered in airborne, shipboard, and ground military platforms. This relay is configured as a double-pole, double-throw switching device, meaning it provides two independently switched sets of contacts that can each connect to one of two possible circuit paths, controlled by a single energized coil. This configuration is commonly used in applications requiring simultaneous switching of two separate circuits, such as redundant power path switching, dual-channel signal routing, or coordinated control of multiple subsystems from a single control signal. The relay operates on momentary, non-latching actuation, meaning the contacts return to their de-energized state as soon as coil power is removed, rather than remaining in their last-commanded position. The coil is designed for direct-current control voltage typical of military and aerospace 28-volt electrical systems, a standard power bus voltage used extensively in aircraft, military vehicles, and shipboard electrical systems. The device's flange-style mounting construction allows it to be securely fastened to a chassis or panel, providing the mechanical stability needed to maintain reliable contact performance under the sustained vibration and shock loading common in military platform environments. Internal contact construction uses a silver-cadmium-oxide contact material, chosen for its strong arc-resistance and resistance to contact welding under repeated switching of inductive or resistive loads. As a hermetically sealed device manufactured to a formal military specification, the relay undergoes rigorous qualification and lot-acceptance testing to verify long-term mechanical and electrical performance, including extended life-cycle switching tests, vibration and shock qualification, and environmental exposure testing. This makes the part suitable for use in flight-critical, mission-critical, or other high-reliability electromechanical switching applications where field failure is not an acceptable risk. The relay is supplied with through-hole solder-pin terminations for both coil and contact connections, supporting traditional through-hole assembly methods consistent with the conservative, well-proven manufacturing processes favored in military and aerospace hardware production.
