A2K1CSQ48VDC1.6D

Relay Automotive Overview

The A2K1CSQ48VDC1.6D is a sealed automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications in vehicle electrical systems. It features an SPDT (Form C) contact arrangement with a coil voltage of 48 VDC. The unit supports quick connect mounting and socketable installation. Key electrical parameters include a maximum switching current of 60 A, a maximum switching voltage of 110 VDC, and a coil resistance of 1.44 kOhms. The coil power consumption is rated at 1.6 W.

Relay Automotive Feature Summary

• SPDT contact configuration providing single pole double throw switching capability
• Sealed construction suitable for demanding automotive environments
• Socketable design allowing for easy replacement and maintenance

Relay Automotive Applications

• Automotive electrical systems
• High-current circuit control
• Vehicle accessory power management

Relay Automotive Procurement Notes

Verify the specific ordering suffix to confirm the inclusion of internal components such as diodes or resistors, as these variations affect functionality. Ensure the 48 VDC coil voltage matches the target system requirements. Confirm that the 60 A current rating and 110 VDC voltage limit are sufficient for the intended load. Check compatibility with standard relay sockets if socketed installation is planned.

Relay Automotive Selection Notes

Select this component when a 48 VDC control signal is available and a changeover contact is required. The 60 A capacity suits heavy loads where smaller relays would fail. Consider the physical dimensions and terminal type for PCB or harness integration. Verify thermal dissipation needs given the 1.6 W coil power in enclosed spaces.
