Frequently Asked Questions
Q: Is this relay socket compatible with standard 40A automotive SPDT relays?
A: Yes. This PCB relay socket is designed to accept standard 4-pin and 5-pin SPDT automotive relays rated up to 40 amps, making it compatible with most common automotive relay types used in cars, motorcycles, and other motor vehicles.
Q: Can this socket handle high-temperature environments like under the hood of a car?
A: Absolutely. The heat-stabilized thermoplastic housing is rated for continuous use at up to 130°C, making it well-suited for installation in engine bays and other high-temperature automotive environments.
Q: What is the difference between the 4-pin and 5-pin versions?
A: A 4-pin relay socket is used with SPST (Single Pole Single Throw) relays that have one switched circuit, while a 5-pin socket accommodates SPDT (Single Pole Double Throw) relays that can switch between two circuits (normally open and normally closed). Choose the version that matches your relay type.
