Configuration and Construction of Automotive Relays

  • From a safety perspective, the use of the automotive relay requires manufacturers of automobiles and automotive equipment to confirm specifications and conduct evaluation tests. Therefore, these products are for sale to automotive manufacturers and automotive component manufactures only.
  • Please inquire with manufacturers of automobiles and automotive equipment about the specifications of automotive relay mounted in vehicle bodies and equipment.
  • Please understand that safety considerations prevent us from receiving inquiries from or dealing with private customers.

1. Protective Construction

1. Flux-Tight

The relay is constructed so that flux will not enter inside the relay during automatic soldering. However, cleaning is not possible.

2. Sealed

Construction is designed to prevent seeping of flux when soldering and cleaning fluid when cleaning.
