A2HM1ASQ12VDC1.6R

Relay Automotive Overview

The A2HM1ASQ12VDC1.6R is a sealed SPST-NO automotive relay from the CIT A2HM series, designed for high-current applications. It features a 12VDC coil with a 150mA current draw and 1.6W power consumption. The switch contacts are rated for a maximum switching voltage of 75VDC and a contact rating of 50A. Constructed with AgSnO2 contact material, this non-latching relay utilizes quick connect termination and is suitable for base mounting in automotive environments.

Relay Automotive Feature Summary

• Sealed construction for environmental protection
• High switching capacity up to 50A
• Quick connect termination for easy installation

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories
• Heavy-duty circuit control

Relay Automotive Procurement Notes

Verify the specific suffix 'R' indicates the inclusion of a resistor on the coil circuit, as distinct variants may lack this component. Confirm that the 50A contact rating aligns with your system's peak load requirements. Ensure the quick connect pin dimensions match your PCB or harness connectors. Check RoHS compliance status if required by your manufacturing standards.

Relay Automotive Selection Notes

Select this model when a single normally open contact is required for loads up to 50A at 12VDC. The sealed design makes it suitable for harsh automotive environments where moisture or dust resistance is necessary. Compare against standard A2M series models if lower current ratings (40A) are sufficient, as the A2HM offers higher capacity.

Relay Automotive Part Context

This part belongs to the CIT A2HM series of automotive relays, which are characterized by their robust sealing and high current handling capabilities. The series is certified under QS-9000 and ISO-9002 standards, ensuring quality for automotive OEM applications. The A2HM variant specifically distinguishes itself with a 50A contact rating compared to the 40A rating found in the standard A2M series.

Relay Automotive Replacement Considerations

The A2HM1ASQ12VDC1.6 is a direct functional substitute if the resistor is not required. The A2M1ASQ12VDC1.6R is compatible for circuits requiring up to 40A. Verify that the physical footprint and pinout of these alternatives match the existing board layout.
