Relay Automotive Procurement Notes

Verify the specific part number against official CIT documentation to confirm the 50A rating, as datasheets may vary between 40A and 50A specifications. Ensure the 24VDC coil voltage matches the target circuit requirements. Check for RoHS compliance status if environmental regulations apply to the assembly. Confirm the presence of internal blowout magnets if arc suppression is required for inductive loads.

Relay Automotive Selection Notes

Select this component when a compact SPDT relay is needed for 24VDC automotive environments. The 50A switching capacity supports heavy loads such as headlights or starter circuits. Consider the available mounting styles for PCB integration or harness connections. Evaluate the coil power consumption against available supply current to ensure stable operation without excessive heat generation.

Relay Automotive Part Context

This model belongs to the CIT automotive relay family, designed for robust performance in vehicle electrical architectures. It shares physical dimensions and mounting standards with other ISO-sized relays, facilitating direct replacement in existing designs. The series emphasizes reliability under vibration and thermal stress typical of automotive applications.

Relay Automotive Replacement Considerations

Compatible substitutes include models with identical SPDT contact forms and 24VDC coil ratings. Verify that alternative parts support the required 50A switching current and 75VDC maximum voltage. Ensure mechanical footprint compatibility for PCB or panel mounting.

Relay Automotive FAQ

What is the contact arrangement for this relay?

The A2H1CSP24VDC1.6D uses an SPDT (Single Pole Double Throw) contact arrangement, also known as Form C.

Does this relay have a latching mechanism?

No, the A2H1CSP24VDC1.6D is a non-latching relay, meaning it returns to its default state when de-energized.
