A2KM1CSP12VDC1.6

Relay Automotive Overview

The A2KM1CSP12VDC1.6 is an ISO-sized automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a 12VDC coil with a maximum operating voltage of 15.6VDC and consumes 1.6 watts of power. The relay utilizes a Single Pole Double Throw (SPDT) contact arrangement, providing robust switching capabilities up to 120A at 14VDC. Constructed with AgSnO2 contact material, it ensures low initial contact resistance below 30 milliohms. The unit supports quick connect mounting and is certified under QS-9000 and ISO-9002 standards, making it suitable for demanding automotive environments.

Relay Automotive Procurement Notes

Verify the specific contact configuration and coil voltage requirements against the target application circuit before procurement. Confirm that the 120A rating aligns with the load characteristics and that the ISO package dimensions fit the designated PCB or harness layout. Ensure compatibility with the system's thermal management needs given the high current handling capability.

Relay Automotive Selection Notes

Select this component when a high-current SPDT switching solution is required within an ISO-standard footprint. The 12VDC coil specification suits standard automotive electrical systems. Consider the 120A capacity for heavy-duty loads such as fans or pumps. Verify that the quick connect mounting style matches the existing wiring infrastructure and that the internal magnet protection meets the arc suppression requirements of the controlled circuit.

Relay Automotive Part Context

This part belongs to the CIT Relay and Switch automotive series, characterized by compact ISO sizing and high reliability. The product line is engineered for harsh automotive environments, featuring certifications like QS-9000 and ISO-9002. These relays are widely used in vehicle electrical architectures where space efficiency and high current handling are critical design constraints.

Relay Automotive Replacement Considerations

Direct substitutes must match the ISO pinout, 12VDC coil voltage, SPDT configuration, and 120A current rating. Verify that alternative components offer equivalent contact resistance and switching voltage limits. Ensure the replacement maintains the same mounting style and physical dimensions for seamless integration.
