A2M1ASQ24VDC1.6R

Relay Automotive Overview

The A2M1ASQ24VDC1.6R is a sealed automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications in vehicle electrical systems. It features a single-pole single-throw normally open (SPST-NO) contact arrangement capable of handling up to 40A at 14VDC. The unit operates on a 24VDC coil with a resistance of 90 Ohms and consumes 1.6W of power. Key specifications include a maximum switching voltage of 75VDC, initial contact resistance under 30 milliohms, and an AgSnO2 contact material. The relay utilizes quick connect terminals for mounting and is RoHS compliant.

Relay Automotive Feature Summary

• Sealed construction suitable for harsh automotive environments
• High current capacity up to 40A for heavy-duty switching
• Quick connect terminal mounting for simplified installation

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power distribution
• General automotive load switching

Relay Automotive Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm if it denotes a specific packaging variant or environmental rating distinct from the base model. Ensure the component matches the required 24VDC coil voltage and SPST-NO configuration for your circuit design. Cross-reference the datasheet for exact dimensional tolerances and thermal operating limits before finalizing procurement.

Relay Automotive Selection Notes

Select this relay when a 24VDC control signal must switch a high-current DC load up to 40A. The SPST-NO form factor is appropriate for simple on/off control applications. Consider the sealed design for protection against moisture and dust compared to unsealed alternatives. Verify that the quick connect terminal style aligns with the available harness connectors in the assembly.

Relay Automotive Part Context

This component belongs to the CIT A2 series of automotive relays, which are characterized by compact dimensions and robust switching capabilities. The series is widely utilized in modern vehicle architectures requiring reliable electromechanical switching for accessories and lighting. The A2 series offers various contact arrangements and coil voltages to accommodate different system requirements.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A2 series relays with identical 24VDC coil ratings and 40A SPST-NO contacts, such as the A2M1ASQ24VDC1.6D. Ensure any replacement maintains the same contact material (AgSnO2) and sealing characteristics to preserve performance reliability in automotive applications.
