Relay-Socket and Surface Mount, 5 Terminals	Sockets with Crimp- On Terminals	Sockets with Wire Leads

These relays handle the high starting (inrush) currents that often occur when turning on a vehicle. Also known as ISO relays, their blade terminals meet ISO 8092-1 dimensional standards to fit in road vehicles for easy maintenance and repair.

Relays with surge suppression coverage prevent damage to sensitive equipment by reducing the 300V to 500V spike that happens when you switch relays off.

Surface Mount—Relays for surface mounting have a tab for added security in high-vibration applications.

Partial—Relays with partial surge suppression coverage bring this spike down to 100V.

Full—Relays with full surge suppression coverage eliminate the voltage spike.

Dual Output—Relays with dual output let you control two separate loads or circuits independently. For example, in a car window, these relays could control it moving up and down.

Weatherproof Vehicle Relays


Relay-Socket Mount	Relay-Socket and Surface Mount	Sockets with Crimp- On Terminals	Sockets with Wire Leads

An extended housing shields the terminals on these relays from weather. They're also rated IP54—when they're plugged into the relay socket, they're sealed to keep splashing water, like rain, from getting inside. They handle high starting (inrush) currents that often occur when turning on a vehicle. To prevent damage to sensitive equipment, these relays will partially suppress a momentary surge in voltage when the relay switches off. They’ll take a voltage spike of 300V to 500V and bring it down to 100V.

Surface Mount—Relays for surface mounting have a tab for added security in high-vibration applications.

Solid State Vehicle Relays


	Sockets with Crimp- On Terminals	Sockets with Wire Leads

With no moving parts, these solid state relays require less maintenance and last longer, switch faster, and are quieter than mechanical relays. They can handle high starting (inrush) currents. The blade terminals meet ISO 8092-1 dimensions, ensuring they are compatible with the electrical connections in road vehicles you need to maintain or repair. Also known as ISO relays or automotive relays.
