Relay Automotive Procurement Notes

Verify that the specific suffix 'R' denotes the inclusion of the internal resistor, as this affects coil resistance values compared to non-resistor variants. Confirm the requirement for the metal bracket and shroud assembly matches the mechanical mounting constraints of the target application. Ensure the 12VDC coil voltage aligns with the vehicle's electrical architecture.

Relay Automotive Selection Notes

Select this model when a sealed relay with a built-in resistor is required for 12VDC automotive circuits. The SPDT configuration allows for versatile switching between normally open and normally closed states. The quick connect pins facilitate rapid assembly without soldering. Consider the physical dimensions and bracket requirements for enclosure space limitations.

Relay Automotive Part Context

This component belongs to the CIT Mini ISO automotive relay family. It shares form factor similarities with other A2 series relays but is distinguished by its sealed design and integrated resistor. The part number indicates the SPDT contact arrangement, 12VDC coil, and specific termination style.

Relay Automotive Replacement Considerations

Compatible substitutes include the A2S1CSQ12VDC1.6R and A2M1USP12VDC1.6. Verify that replacement parts maintain the same sealed status, coil power rating, and contact current capacity to ensure functional equivalence in the existing circuit.

Relay Automotive FAQ

What is the function of the internal resistor in this relay?

The internal resistor limits the coil current to achieve the specified 1.6W power rating at 12VDC, eliminating the need for external current-limiting components.

Does the metal bracket serve only a mounting purpose?

No, the metal bracket also acts as a shroud, providing a sealed environment to protect the internal contacts from moisture and contaminants.
