A2KM1ASP12VDC1.6D

Relay Automotive Overview

The A2KM1ASP12VDC1.6D is an ISO-sized automotive relay manufactured by CIT Relay and Switch, designed for demanding vehicle applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration capable of switching up to 120A at 12VDC. The unit utilizes a non-latching coil with a 12VDC rated voltage and quick-connect terminals measuring 0.250 inches (6.3mm). Constructed with sealed housing and internal blowout magnets, it supports DC motor and lamp control while ensuring reliable performance in harsh environments.

Relay Automotive Feature Summary

• High current switching capacity suitable for heavy loads
• Sealed construction for environmental protection
• Internal blowout magnets for arc suppression
• ISO standard form factor for easy integration

Relay Automotive Applications

• DC motor control systems
• Automotive lamp circuits
• General power management in vehicles
• Heavy-duty accessory control

Relay Automotive Procurement Notes

Verify the specific contact rating requirements against the datasheet, as high-current variants may have distinct thermal characteristics. Confirm terminal type compatibility with existing harnesses. Check RoHS compliance status if required for specific regional regulations. Ensure mounting space accommodates the ISO footprint dimensions.

Relay Automotive Selection Notes

Select this model when high current handling above standard automotive limits is necessary. Compare with lower-rated alternatives like the A2S1ASQ series if load currents are significantly lower. Consider the sealed design benefits over unsealed versions for exposed installations. Evaluate coil power consumption against available supply capacity.

Relay Automotive Part Context

This component belongs to the A2 series of automotive relays from CIT Relay and Switch. The series offers various contact configurations and current ratings tailored for vehicle electrical systems. The A2KM1ASP variant specifically addresses high-load applications requiring robust switching capabilities within a standardized ISO package size common in modern automotive designs.

Relay Automotive Replacement Considerations

Public confirmed substitute part numbers include A2KM1ASP12VDC1.6. Verify pinout and terminal orientation compatibility before substitution. Ensure the replacement maintains the same SPST-NO contact form and 12VDC coil specification.
