Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's catalog to confirm terminal style and coil specifications. Ensure the selected variant matches the required mounting type and contact arrangement for the target application. Cross-reference the part number with official distributor databases to confirm availability and compliance status.

Relay Automotive Selection Notes

Select this component based on the 24VDC coil requirement and the need for a 40A SPST-NO contact rating. Consider the operating temperature range and sealing requirements for the installation environment. Verify that the quick connect or PCB pin mounting options align with the system's mechanical constraints.

Relay Automotive Part Context

This model belongs to the CIT A Series automotive relays, designed for high-current switching in vehicle applications. The series offers various coil voltages and contact configurations to support diverse automotive and industrial needs.
