A2HM1CSQ24VDC1.6R

Relay Automotive Overview

The A2HM1CSQ24VDC1.6R is a non-latching electromechanical relay from the CIT A2H series, designed for high-current switching applications. It features a 24VDC coil with a rated current of 75 mA and an SPDT (Form C) contact configuration. The device supports a maximum switching voltage of 75VDC and handles a contact rating of up to 50A. Constructed with AgSnO2 contacts, it offers low initial contact resistance below 30 milliohms. The unit measures 26.0 x 26.0 x 24.5 mm, providing a compact form factor suitable for PCB pin or quick connect mounting in automotive and industrial environments.

Relay Automotive Feature Summary

• SPDT contact arrangement enables single circuit control with common, normally open, and normally closed terminals
• High current capacity supports demanding loads up to 50 amperes at rated voltage
• Compact physical dimensions facilitate integration into space-constrained assemblies

Relay Automotive Applications

• Automotive electrical systems requiring regulated 24V supply control
• Industrial machinery utilizing standard 24VDC power sources
• Lamp accessories and lighting control circuits

Relay Automotive Procurement Notes

Verify the specific suffix 'R' against manufacturer documentation to confirm lead time or tape-and-reel packaging specifications. Ensure the 24VDC coil voltage aligns with system power rails. Confirm that the 50A contact rating meets peak load requirements without exceeding thermal limits during continuous operation.

Relay Automotive Selection Notes

Select this model when a single pole double throw configuration is required for 24VDC systems. The 50A rating exceeds standard automotive relay capabilities, making it suitable for heavy-duty loads. Consider the physical size constraints and verify that PCB pin or quick-connect mounting options fit the assembly design.
