A51CO12VDC1.6U

Relay Automotive Overview

The A51CO12VDC1.6U is an automotive electromechanical relay manufactured by CIT Relay and Switch, featuring a Single Pole Double Throw (SPDT) contact arrangement. It operates with a 12VDC coil voltage and supports a maximum switching current of 40A at 14VDC. The unit utilizes Silver Tin Oxide (AgSnO2) contacts to ensure reliable performance under high-load conditions. Designed for durability in demanding environments, it complies with RoHS standards and offers quick-connect terminal options for efficient PCB integration.

Relay Automotive Feature Summary

• SPDT contact configuration provides versatile circuit control capabilities
• High current handling capacity suitable for heavy-duty automotive loads
• RoHS compliant construction ensures environmental safety standards

Relay Automotive Applications

• Automotive electrical systems
• Industrial control circuits
• Lamp accessory power management

Relay Automotive Procurement Notes

Verify the specific contact arrangement suffix 'CO' corresponds to SPDT requirements before ordering. Confirm that the 12VDC coil voltage matches the system supply. Ensure the quick-connect terminal style aligns with the target PCB footprint or harness connector specifications to guarantee proper mechanical and electrical integration.

Relay Automotive Selection Notes

Select this model when a single input must switch between two distinct output paths within automotive applications. The 40A rating accommodates significant load currents, making it suitable for high-power accessories. Consider the physical dimensions and mounting style to ensure compatibility with existing enclosure constraints and assembly processes.

Relay Automotive Part Context

This component belongs to the CIT A51 series of automotive relays, designed for robust performance in vehicle environments. The series emphasizes reliability and compliance with industry standards such as ISO-9002. The A51CO variant specifically addresses applications requiring double throw functionality, expanding design flexibility compared to standard single pole single throw alternatives.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A51 series models with matching SPDT configurations and 12VDC coils, such as A51CE12VDC1.6U, provided the pinout and terminal styles are compatible. Cross-manufacturer replacements require verification of coil resistance, contact material, and dimensional tolerances to ensure functional equivalence.
