Relay Automotive Procurement Notes

Verify the specific ordering suffix against official CIT documentation to confirm terminal style and mounting type. Ensure the selected variant matches the required coil voltage and contact configuration for the target application. Cross-reference part numbers with authorized distributors to confirm availability and authenticity before finalizing procurement plans.

Relay Automotive Selection Notes

Select this component based on the requirement for a 24VDC coil operation and a 40A SPST-NO contact rating. Consider the sealed design and wide operating temperature range (-40°C to 125°C) for suitability in harsh environments. Verify that the quick connect or PCB pin mounting option aligns with the system's mechanical constraints.

Relay Automotive Part Context

This model belongs to the A2 series of automotive relays manufactured by CIT Relay and Switch. The series is characterized by its robust switching capabilities and compact form factor, making it suitable for space-constrained installations in vehicles and industrial machinery requiring reliable high-current control.

Relay Automotive Replacement Considerations
