A2K1ACQ12VDC1.6D

Relay Automotive Overview

The A2K1ACQ12VDC1.6D is an automotive relay manufactured by CIT Relay and Switch, designed for high-current applications. It features a single-pole double-throw (SPDT) contact configuration capable of switching up to 120A. The device operates with a 12VDC coil voltage and includes an integrated diode for protection against inductive kickback. Constructed as a sealed unit, it utilizes quick-connect terminals for mounting and is rated for operation within a temperature range of -40°C to 125°C.

Relay Automotive Feature Summary

• High current switching capacity of 120A
• Integrated flyback diode for coil protection
• Sealed construction for environmental resistance
• Quick-connect terminal interface

Relay Automotive Applications

• Automotive electrical systems
• Heavy-duty lighting circuits
• Industrial motor control
• Power distribution units

Relay Automotive Procurement Notes

Verify the specific contact arrangement and coil specifications against the official datasheet before procurement. Confirm that the integrated diode polarity matches the circuit design requirements. Ensure the quick-connect terminal dimensions are compatible with the intended harness or PCB layout. Check for any updated regulatory compliance certifications required for the target market.

Relay Automotive Selection Notes

Select this component when a high-current SPDT switching solution is required in space-constrained environments. The sealed design makes it suitable for harsh conditions where moisture or dust exposure is a concern. The integrated diode simplifies circuit design by eliminating the need for external suppression components. Ensure the operating voltage aligns with the 12VDC coil specification.

Relay Automotive Part Context

This part belongs to the A2 series of automotive relays from CIT Relay and Switch. The series is characterized by compact dimensions and robust performance for vehicle and industrial use. The 'D' suffix typically indicates the inclusion of a protective diode across the coil terminals. This model represents a high-current variant within the lineup, distinguishing it from lower-rated counterparts.

Relay Automotive Replacement Considerations

Direct substitutes must match the 120A rating, SPDT configuration, and 12VDC coil voltage. Verify that replacement parts also include an integrated diode if the original circuit relies on it. Ensure physical dimensions and terminal types are compatible with existing mounting structures.
