A2M1CSQ24VDC1.6

Relay Automotive Overview

The A2M1CSQ24VDC1.6 is a sealed automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a 24VDC coil voltage with a maximum of 31.2VDC and a power consumption of 1.6 watts. The unit utilizes an SPDT (Single Pole Double Throw) contact arrangement, designated as configuration 1C. It supports a maximum switching current of 40A at 14VDC and a maximum switching voltage of 75VDC. The contact material is AgSnO2, ensuring low initial contact resistance below 30 milliohms. The device measures 26.0 x 26.0 x 24.5 mm and includes PCB pin and quick connect mounting options.

Relay Automotive Feature Summary

• Sealed construction suitable for harsh automotive environments
• High switching capacity up to 40A for heavy loads
• Compact form factor with lightweight design
• Versatile mounting via PCB pins or quick connect terminals

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• High-current circuit switching in vehicles

Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required coil voltage and contact configuration. Confirm RoHS compliance status if environmental regulations apply to your assembly. Check manufacturing certifications such as QS-9000 or ISO-9002 if quality standards are mandated. Ensure the physical dimensions fit within the designated enclosure space. Validate that the 1.6W coil power rating aligns with the available driver circuit capacity.

Relay Automotive Selection Notes

Select this model when a 24VDC control signal is present in the system architecture. Choose the SPDT configuration if both normally open and normally closed paths are required for load management. Consider the 40A current rating for applications involving high-power accessories like lighting or motors. Verify that the quick connect or PCB pin termination suits the existing board layout or wiring harness design.

Relay Automotive Part Context

This component belongs to the CIT A2M series of automotive relays, which are characterized by their robust sealing and high current handling capabilities. The series is widely used in vehicle electrical networks where reliability under vibration and temperature fluctuations is critical. The A2M1CSQ variant specifically denotes the sealed, SPDT configuration with quick connect terminals.

Relay Automotive Replacement Considerations

Direct substitutes must match the 24VDC coil voltage, 1.6W power rating, and SPDT contact arrangement. Verify that alternative parts support the same 40A switching current and 75VDC maximum voltage. Ensure mechanical compatibility regarding the 26.0 x 26.0 x 24.5 mm footprint and terminal type.
