A2K1CSP48VDC1.6R

Relay Automotive Overview

The A2K1CSP48VDC1.6R is an ISO-sized automotive relay manufactured by CIT Relay and Switch. It features a single pole double throw (SPDT) contact arrangement, designated as Form C. The coil operates at a rated voltage of 48VDC with a maximum limit of 31.2VDC for the specific variant context, though standard ISO coils typically align with system voltages. The unit supports switching up to 110VDC and handles high currents suitable for DC motor and lamp control applications.

Relay Automotive Feature Summary

• ISO sized automotive relay form factor
• Internal blowout magnets for arc suppression
• Capable of switching up to 110VDC
• Suitable for DC motor and lamp control

Relay Automotive Applications

• Automotive DC motor control circuits
• Automotive lamp accessory control
• High current switching in vehicle electrical systems

Relay Automotive Procurement Notes

Verify the exact coil voltage rating against the specific datasheet revision, as 48VDC variants may have distinct electrical tolerances compared to standard 12V or 24V units. Confirm the contact arrangement matches the required SPDT configuration for the target circuit design. Ensure the chassis mount style fits the available PCB or panel space within the vehicle application.

Relay Automotive Selection Notes

Select this component when an ISO footprint is required for high-voltage switching up to 110VDC. The internal blowout magnets make it suitable for inductive loads like motors. Verify that the 48VDC coil supply is available in the system architecture before integrating into the harness design.

Relay Automotive Part Context

This part belongs to the CIT A2 series of automotive relays, designed to meet ISO standards for size and mounting. The 'CSP' suffix indicates the specific contact and pin configuration. These relays are engineered for harsh automotive environments, providing reliable switching for accessories and power distribution modules.

Relay Automotive Replacement Considerations

Cross-reference with other ISO Form C relays from manufacturers such as Omron, TE Connectivity, or Panasonic. Ensure the replacement maintains the same coil voltage, current rating, and physical dimensions to fit existing board layouts without modification.
