A51AE12VDC1.6U

Relay Automotive Overview

The A51AE12VDC1.6U is an automotive relay manufactured by CIT Relay and Switch, featuring a SPST-NO contact arrangement with a 40A switching capacity at 14VDC. It utilizes a 12VDC coil with a maximum voltage of 15.6VDC and a resistance of 90 ohms +/- 10%. The unit supports PCB pin mounting and quick connect options, measuring 26.0 x 26.0 x 24.5 mm. Contact resistance is less than 30 milliohms initially, using AgSnO2 material. It is certified under QS-9000 and ISO-9002 standards.

Relay Automotive Feature Summary

• SPST-NO configuration with high current handling capability
• Compact physical dimensions for space-constrained installations
• Dual mounting flexibility via PCB pins or quick connects

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• General automotive load switching

Relay Automotive Procurement Notes

Verify the specific suffix 'U' against the manufacturer's official documentation to confirm lead-free compliance status. Ensure the required contact arrangement matches the SPST-NO specification. Cross-reference the coil voltage rating with the system power supply to prevent operational failure. Confirm that the mounting style aligns with the target PCB footprint or connector requirements.

Relay Automotive Selection Notes

Select this component when a single-pole normally-open switch is required for moderate current loads in automotive environments. The 12VDC coil compatibility makes it suitable for standard vehicle electrical architectures. Consider the physical size constraints and available mounting methods during the design phase to ensure proper integration into the assembly.
