A2F1CSQ12VDC1.6R

Relay Automotive Overview

The A2F1CSQ12VDC1.6R is a sealed automotive relay manufactured by CIT Relay and Switch, featuring a Single Pole Double Throw (SPDT) contact configuration. It operates with a 12VDC coil voltage and supports a maximum switching current of 40A at 75VDC. The unit utilizes quick connect termination for mounting and includes an integrated resistor within the coil circuit. Designed for high-capacity switching in automotive environments, it offers reliable performance across a wide temperature range.

Relay Automotive Feature Summary

• Sealed construction suitable for harsh automotive environments
• High switching capacity up to 40A for heavy loads
• Integrated coil resistor for circuit protection
• Quick connect termination for rapid installation

Relay Automotive Applications

• Automotive lighting control systems
• Vehicle accessory power distribution
• Industrial equipment switching applications

Relay Automotive Procurement Notes

Verify that the specific suffix 'R' denotes the inclusion of the internal coil resistor, as standard variants may lack this component. Confirm the SPDT contact arrangement matches the circuit design requirements. Ensure the quick connect pin dimensions align with the target socket or PCB footprint. Check RoHS compliance status if environmental regulations apply to the final assembly.

Relay Automotive Selection Notes

Select this model when a sealed relay with high current handling is required for automotive use. The SPDT configuration allows for switching between two separate circuits. Verify that the 12VDC coil voltage matches the vehicle's electrical system. Consider the physical size constraints, as the unit is designed for compact mounting flange installation.

Relay Automotive Part Context

This component belongs to the CIT A2 series of automotive relays, which are characterized by their robust sealing and high current ratings. The series is widely used in transportation and industrial sectors where reliability under vibration and moisture is critical. The A2 series typically features both PCB and quick connect mounting options.

Relay Automotive Replacement Considerations

Direct substitutes must match the 12VDC coil voltage, SPDT contact form, and 40A current rating. Verify that any replacement also includes the internal coil resistor if present in the original part. Ensure the quick connect terminal style and mounting flange dimensions are compatible with the existing hardware.
