A2KM1ACQ24VDC1.6

Relay Automotive Overview

The A2KM1ACQ24VDC1.6 is an automotive relay from the CIT Relay and Switch A2K series, designed for chassis mounting applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a maximum switching capacity of 40 amperes. The coil operates at 24 volts DC with a current draw of 66.7 mA and a power consumption of 1.6 watts. The unit utilizes quick-connect terminals measuring 0.250 inches (6.3 mm) for electrical connections. It is rated for a wide operating temperature range from -40°C to 125°C, ensuring reliability in demanding automotive environments.

Relay Automotive Feature Summary

• High current switching capability up to 40A for robust load handling
• Compact design offering small size and light weight for efficient space utilization
• Sealed construction provides protection against environmental contaminants
• Compatible with standard quick-connect terminal interfaces for simplified wiring

Relay Automotive Applications

• Automotive electrical systems
• Agriculture machinery control circuits
• Industrial equipment relay modules

Relay Automotive Procurement Notes

Verify the specific coil voltage rating of 24VDC and the SPST-NO contact form factor to ensure compatibility with the target circuit design. Confirm that the chassis mount style and quick-connect terminal dimensions align with the available panel or board space. Check for RoHS compliance requirements if the application mandates restricted substance standards. Ensure the operating temperature range meets the environmental conditions of the intended installation site.

Relay Automotive Selection Notes

Select this component when a high-current automotive relay is required for 24VDC control circuits. The 40A rating supports heavy loads such as motors, heaters, or lighting arrays. Consider the physical dimensions and chassis mount requirement during mechanical design. Compare against other A2 series variants if different contact forms or coil voltages are needed. Verify terminal type compatibility with existing harness connectors before finalizing the selection.

Relay Automotive Part Context

This part belongs to the A2 series of automotive relays manufactured by CIT Relay and Switch. The series is characterized by its sealed construction and high switching capacity, making it suitable for harsh environments. The A2K sub-series specifically denotes the 24VDC coil variant within this family. These relays are commonly used in vehicle and industrial applications where reliable high-current switching is essential.

Relay Automotive Replacement Considerations

Direct substitutes within the same series include models with identical coil voltage and contact form but potentially different terminal styles or base configurations. Variants such as A2F1ASPP24VDC1.6 offer similar performance with PCB pin mounting options instead of chassis mount. Ensure any replacement maintains the 40A switching capacity and 24VDC coil specification to preserve circuit functionality.
