A2K1CSP24VDC1.6D

Relay Automotive Overview

The A2K1CSP24VDC1.6D is an ISO-sized automotive relay manufactured by CIT Relay and Switch, designed for through-hole mounting. It features a non-latching coil with a rated voltage of 24VDC and a coil resistance of 360 ohms. The switch contact configuration is SPDT (1 Form C), capable of handling up to 40A at 14VDC or 30A at 14VDC for normally closed operations. Maximum switching power reaches 630W at 75VDC, with initial contact resistance under 30 milliohms. Operating temperature ranges from -40°C to 125°C.

Relay Automotive Feature Summary

• Incorporates internal blowout magnets to enhance arc suppression during high-current switching operations.
• Features a sealed construction suitable for demanding automotive environments and lamp control applications.
• Supports both PCB pin and quick connect mounting options for flexible integration.

Relay Automotive Applications

• Automotive DC motor control circuits
• Vehicle lamp accessory management systems
• General purpose industrial switching requiring high current capacity

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure correct coil voltage and contact configuration. Confirm that the required package type matches the available through-hole or quick-connect variants. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the supplier provides valid traceability documentation for automotive-grade components.

Relay Automotive Selection Notes

Select this component when designing circuits requiring high current switching capabilities within standard ISO relay footprints. The SPDT configuration offers versatility for both normally open and normally closed logic requirements. Consider the thermal operating range and magnetic blowout features for reliability in harsh automotive electrical environments compared to lower-rated general-purpose relays.

Relay Automotive Part Context

This model belongs to the A2K series of automotive relays from CIT Relay and Switch. The series is characterized by robust construction and high switching capacity, specifically tailored for vehicle electrical systems. It complements other series like J118 and A3K, offering distinct form factors and current ratings for diverse automotive and industrial applications.

Relay Automotive Replacement Considerations

Direct substitutes include models within the same A2K series with identical coil voltages and contact forms. Verify mechanical footprint compatibility before replacing. Cross-reference with CIT's official substitution guide to ensure equivalent electrical performance and mounting specifications are maintained.
