A2HM1CSQ24VDC1.6

Relay Automotive Overview

The A2HM1CSQ24VDC1.6 is an automotive relay from the CIT Relay and Switch A2H series, designed for high-current switching applications. It features a SPDT (1 Form C) contact arrangement with a maximum switching current of 50A at 75VDC. The coil operates at 24VDC with a resistance of 360 Ohms and consumes 1.6W of power. Key electrical parameters include a must-operate voltage of 15.6 VDC and a must-release voltage of 2.4 VDC. The device supports chassis mounting and utilizes quick connect terminals.

Relay Automotive Feature Summary

• High switching capacity up to 50A
• SPDT contact configuration for versatile circuit control
• Sealed construction suitable for automotive environments

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories
• Industrial control circuits requiring high current switching

Relay Automotive Procurement Notes

Verify the specific suffix 'D' in the part number against official CIT documentation to confirm any distinct manufacturing or packaging variations. Ensure compatibility with 24VDC control circuits and validate that the 50A rating aligns with the load requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a SPDT configuration is required for loads up to 50A in automotive or industrial settings. The 24VDC coil voltage makes it suitable for standard heavy-duty vehicle electrical architectures. Consider the chassis mount style and quick-connect terminals for ease of integration into existing relay bases or harnesses.

Relay Automotive Part Context

This relay belongs to the A2H series, which is characterized by large switching capacities and compact dimensions. The series is certified under QS-9000 and ISO-9002 standards, indicating adherence to strict quality management systems for automotive components. The design emphasizes reliability in harsh operating conditions typical of vehicle applications.

Relay Automotive Replacement Considerations

Direct substitutes within the same series include variants with different coil voltages such as A2HM1CSQ12VDC1.6 or A2HM1CSQ6VDC1.6. For identical specifications, ensure the replacement maintains the SPDT form factor and 50A current rating. Cross-reference with distributor databases for exact pinout and mechanical dimension compatibility.
