1616138-2

Overview

The TE Connectivity 1616138-2 is a general-purpose electromechanical relay designed for high-reliability applications in aerospace, defense, and marine environments. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a robust 750 A current rating and supports switching voltages up to 1800 VDC. The unit operates on a 12 VDC coil voltage, requiring a minimum pull-in voltage of 9.9 VDC and releasing at 2 VDC. Mechanical operation includes a working time of 40 ms and a release time of 20 ms. Designed for base mounting with terminal termination, it functions within a temperature range of -40°C to 85°C.

Feature Summary

• Hermetically sealed construction suitable for harsh military and aerospace conditions
• High-current capacity rated for 750 A switching loads
• FAA/PMA certified for aviation compliance requirements

Applications

• Military aircraft electrical systems
• Missile defense subsystems
• Marine navigation equipment

Procurement Notes

Verify the specific datasheet revision and FAA/PMA certification status prior to procurement. Confirm that the 12VDC coil specification matches the system power supply. Ensure mechanical compatibility with the intended base mount interface. Check for any specific environmental qualification certificates required by the project specifications.

Selection Notes

Select this component when high current switching and aviation certification are mandatory. The 12VDC coil requirement must align with available control signals. Consider the 750 A rating against peak load demands. Verify that the SPST-NO configuration meets the circuit logic requirements. Evaluate the -40°C to 85°C operating range against environmental conditions.

Part Context

This part belongs to the TE Connectivity Aerospace, Defense and Marine portfolio, which provides rugged connectivity solutions for mission-critical sub-systems.
