A2K1CSP48VDC1.6

Relay Automotive Overview

The A2K1CSP48VDC1.6 is an automotive relay manufactured by CIT Relay and Switch, designed for chassis mounting applications. It features a Single Pole Double Throw (SPDT) contact arrangement, classified as Form C. The coil operates at a rated voltage of 48 VDC with a maximum limit of 31.2 VDC, consuming 1.6W of power. The coil resistance is specified at 90 ohms with a tolerance of +/- 10%. The switch contacts support a maximum switching current of 40A at 75VDC, with a maximum switching power of 630W. Contact material is AgSnO2, ensuring initial contact resistance below 30 milliohms.

Relay Automotive Feature Summary

• High switching capacity up to 40A for robust load handling
• Compact design with small size and light weight characteristics
• Versatile mounting options including PCB pin and quick connect interfaces

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• Chassis-mounted circuit protection

Relay Automotive Procurement Notes

Verify the specific contact configuration matches the required SPDT (Form C) application. Confirm that the 48VDC coil voltage aligns with the system's power supply capabilities. Ensure the mechanical dimensions fit the designated chassis mounting space. Check for RoHS compliance requirements if environmental regulations apply to the final assembly.

Relay Automotive Selection Notes

Select this component when a high-current SPDT switching solution is needed in automotive environments. The 40A rating suits heavy loads compared to standard relays. The 48VDC coil specification requires compatible control circuits. Consider the chassis mount style for vibration-resistant installations typical in vehicle under-hood or interior panels.

Relay Automotive Part Context

This part belongs to the CIT automotive relay series, characterized by large switching capacities and compact form factors. These relays are certified under QS-9000 and ISO-9002 standards, indicating adherence to quality management systems for automotive components. The series supports various coil voltages and contact arrangements to meet diverse vehicle electrical demands.

Relay Automotive Replacement Considerations

Direct substitutes must match the SPDT (Form C) configuration, 48VDC coil voltage, and 40A current rating. Verify physical footprint compatibility for chassis mounting. Cross-reference with other CIT models like A2M1USP12VDC1.6 only if voltage and contact type differences are acceptable.
