A2F1ACQ24VDC1.6R

Relay Automotive Overview

The A2F1ACQ24VDC1.6R is an automotive electromechanical relay manufactured by CIT Relay and Switch. It features a single-pole single-throw normally open (SPST-NO) contact arrangement rated for 40A at 14VDC. The coil operates on a 24VDC supply with a maximum switching voltage of 75VDC and a maximum switching power of 630W. Key electrical parameters include a coil resistance of 360 Ohms, a pull-in voltage of 16.8VDC, and a release voltage of 2.4VDC. The unit utilizes quick-connect terminals measuring 0.250 inches (6.3mm) and is designed for chassis mounting.

Relay Automotive Feature Summary

• High current switching capacity suitable for demanding automotive loads
• Sealed construction to protect against environmental factors
• Standardized quick-connect terminal interface for simplified assembly

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power distribution
• Industrial control systems requiring high-current switching

Relay Automotive Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm if it denotes a specific tape-and-reel packaging format or a minor mechanical variation compared to the standard non-R variant. Ensure the procurement source provides the original datasheet from CIT Relay and Switch to validate the exact coil resistance and contact rating specifications before finalizing orders.

Relay Automotive Selection Notes

Select this component when a 24VDC control signal is required to switch up to 40A in automotive applications. The SPST-NO configuration is ideal for simple on/off control of high-power loads. Consider the chassis mount style and quick-connect terminals for compatibility with existing harness designs and panel layouts.

Relay Automotive Part Context

This part belongs to the CIT A2 series of automotive relays, which are widely used in vehicle electrical systems. The series is characterized by robust sealing and high current handling capabilities. The A2F1ACQ24VDC1.6R specifically adapts the standard A2 form factor for 24-volt operation, maintaining compatibility with common automotive fuse footprints and mounting standards.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A2 series relays with identical coil voltage and contact ratings, such as the A2S1ASQ24VDC1.6. Verify that any replacement maintains the same SPST-NO contact arrangement, 40A current rating, and 24VDC coil specification to ensure functional equivalence.
