TM1062TX3DUA

The TM1062TX3DUA is a hermetically sealed hybrid time delay relay module manufactured by Pulse Electronics, part of the TM1062 series engineered for precise, repeatable timing control in high-reliability applications. The device integrates a solid-state timing circuit with an electromechanical relay output in a rugged SOP (Small Outline Package) footprint, suitable for surface-mount assembly. Typical characteristics for this series include a fixed or factory-preset time delay interval—available from milliseconds to several hundred seconds—operating from nominal input voltages such as 5V, 12V, or 28V DC. The hermetic construction provides a controlled internal environment, ensuring stable timing accuracy and low contact resistance over wide temperature extremes commonly associated with military and aerospace environments. Relay outputs are generally configured as DPDT or form C contacts, capable of switching moderate loads with gold-plated contacts for low-level signal integrity.

Typical applications span aerospace flight control sequencing, satellite power distribution, missile system safe-arm timing, and industrial safety interlocks where deterministic delay-on-make or delay-on-break functions are critical. In such systems, the module may serve as a delayed engine start relay, a fault-tolerant timer for redundant power supplies, or a controlled power-on sequencing element in avionics bays. Procurement considerations for this class of component include extended lead times common to hermetic hybrid manufacturing, the potential for mandatory source-controlled documentation, and qualification to defense-grade specifications such as MIL-PRF-83726. Engineers should verify part number suffix details—such as the “TX3DUA” variant—for exact input voltage, timing range, and screening level, as military and space-grade options often require additional lot-level traceability, burn-in testing, and QPL conformance. Long-term support should be planned due to possible single-source supply and custom preset configurations.
