A3K1ASP12VDC1.6R

Relay Automotive Overview

The A3K1ASP12VDC1.6R is a Maxi automotive relay manufactured by CIT Relay and Switch, designed for high-current applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a rated current of 80A and a maximum switching voltage of 145VDC. The coil operates at 12VDC with a resistance of 90 Ohms and consumes 1.6W of power. This non-latching relay includes an integrated resistor and utilizes silver tin oxide contacts for durability.

Relay Automotive Feature Summary

• High current capacity of 80A for robust power control
• Integrated resistor for circuit protection and stability
• Sealed construction suitable for demanding environments

Relay Automotive Applications

• Automotive power distribution systems
• Heavy-duty vehicle electrical circuits
• Industrial motor control applications

Relay Automotive Procurement Notes

Verify the specific part number suffix to ensure the inclusion of the integrated resistor, as configurations may vary within the series. Confirm that the 12VDC coil voltage matches the system requirements. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the mounting style aligns with the available socket or PCB layout.

Relay Automotive Selection Notes

Select this component when high current handling up to 80A is required in a compact form factor. The integrated resistor simplifies circuit design by reducing external component count. Verify that the 12VDC coil voltage is compatible with the control logic. Consider the sealed nature of the relay for protection against moisture and dust in harsh operating conditions.

Relay Automotive Part Context

This model belongs to the Maxi relay series from CIT Relay and Switch, known for rugged performance in automotive and industrial sectors. The A3K1ASP12VDC1.6R variant specifically addresses high-load switching needs with a non-latching mechanism. It represents a reliable solution for managing significant electrical loads in vehicles and machinery where space and efficiency are critical constraints.

Relay Automotive Replacement Considerations

Direct substitutes include other Maxi series relays with identical pinouts and ratings, such as the A3K1CSQ12VDC1.6R for SPDT configurations. Ensure any replacement maintains the 80A rating and 12VDC coil specifications. Verify that the integrated resistor feature is present if circuit compatibility depends on it.
