A3KM1ASQ24VDC1.6

Relay Automotive Overview

The A3KM1ASQ24VDC1.6 is an automotive relay manufactured by CIT Relay and Switch, featuring a single-pole single-throw normally open (SPST-NO) contact configuration. It operates with a 24VDC coil voltage and supports a maximum switching current of 80A at 14VDC. The device utilizes quick-connect terminals for mounting and includes an integrated suppression diode. Key electrical parameters include a coil resistance of 360 Ohms, a coil power consumption of 1.6W, and a maximum switching voltage of 75VDC. The unit is designed for chassis installation and complies with RoHS standards.

Relay Automotive Feature Summary

• High current switching capacity up to 80A for demanding automotive loads
• Integrated suppression diode for inductive load protection
• Sealed construction suitable for harsh automotive environments
• Quick-connect terminal interface for simplified assembly

Relay Automotive Applications

• Automotive lighting circuits
• Heater and blower motor control
• Fuel pump activation
• Accessory power distribution

Relay Automotive Procurement Notes

Verify the specific suffix '1.6' against the manufacturer's latest datasheet to confirm the exact coil resistance and pinout configuration. Ensure the application voltage matches the 24VDC rating and that the load current does not exceed the 80A limit. Confirm RoHS compliance requirements if applicable to your supply chain standards. Cross-reference the package style to ensure compatibility with existing PCB or harness connectors.

Relay Automotive Selection Notes

Select this component when high-current switching is required in a compact automotive form factor. The SPST-NO configuration provides simple on/off control for single-circuit loads. Consider the 75VDC maximum switching voltage to ensure compatibility with system transients. The sealed design offers protection against moisture and dust, making it suitable for under-hood or exterior vehicle applications where durability is critical.

Relay Automotive Part Context

This part belongs to the CIT A3M series of automotive relays, which are characterized by high current handling capabilities. The series is designed to meet stringent automotive industry standards for reliability and performance. The A3KM1ASQ variant specifically denotes the SPST-NO configuration with quick-connect terminals and a standard 24VDC coil drive requirement within the broader Maxi relay family.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT Automotive Relays with identical 80A SPST-NO specifications and 24VDC coil ratings. Verify mechanical dimensions and terminal spacing to ensure fitment. Alternative manufacturers offering equivalent automotive-grade relays must match the 75VDC switching voltage and 80A current limits. Check for compatible suppression diode integration in replacement parts.
