A2H1ACQ12VDC1.6R

Relay Automotive Overview

The A2H1ACQ12VDC1.6R is a sealed SPST-NO automotive relay manufactured by CIT Relay and Switch. It features a non-latching coil rated for 12VDC with a current draw of 150 mA. The switch contacts support a maximum switching current of 50A at 75VDC, utilizing AgSnO2 contact material. Designed for robust automotive environments, the unit includes a metal bracket and shroud with quick connect termination style (0.250 inch).

Relay Automotive Feature Summary

• Sealed construction with metal bracket and shroud for environmental protection.
• High switching capacity up to 50A for demanding automotive loads.
• Quick connect termination style facilitates rapid PCB or harness installation.

Relay Automotive Applications

• Automotive lighting circuits
• Motor control applications
• General automotive accessory power distribution

Relay Automotive Procurement Notes

Verify the specific contact rating configuration against the datasheet, as some variants in this series are rated at 40A while others reach 50A. Confirm that the 12VDC coil voltage aligns with the system's electrical architecture. Ensure the quick connect pin dimensions match the target connector specifications to guarantee proper mechanical engagement and electrical continuity during operation.

Relay Automotive Selection Notes

Select this component when a high-current single-pole solution is required for automotive systems. The sealed design offers protection against moisture and dust compared to open relays. Consider the physical footprint and mounting requirements provided by the integrated metal bracket. Verify thermal management needs if operating continuously near the maximum current rating.

Relay Automotive Part Context

This part belongs to the A2 series of automotive relays from CIT Relay and Switch. The series is characterized by compact dimensions and high current handling capabilities suitable for vehicle electrical systems. The A2H variant specifically denotes the 50A contact rating configuration within the broader product family.

Relay Automotive Replacement Considerations

Compatible substitutes include the A2S1ASQ12VDC1.6 and A2M1USP12VDC1.6. Note that these alternatives may have different contact ratings (e.g., 40A) or terminal styles. Verify coil resistance and pinout compatibility before substitution to ensure circuit functionality remains intact.
