DURAKOOL DG82 Series 12V DC 40A SPST Automotive Relay

The DURAKOOL DG82 Series Automotive Relay is a robust and cost-effective solution for high-current switching applications in 12V DC systems. Designed with a compact micro plug-in or PCB mounting footprint, this relay offers exceptional reliability and performance in demanding automotive and industrial environments.

Featuring a single-pole, double-throw (SPDT) contact arrangement, it provides flexible switching options for controlling auxiliary circuits, lighting, motors, and other high-load devices. The contacts are made from durable silver tin oxide indium oxide (AgSnOInO) material, ensuring long life and stable performance even under frequent switching cycles.

A key advantage is its impressive current handling: rated for 40A continuous current and capable of managing up to 120A inrush current, making it suitable for starting motors and inductive loads. The relay is sealed to IP67 standards, offering excellent protection against dust and temporary immersion in water, which is critical for under-bonnet or exposed locations.

Electrical specifications include a 12V DC nominal coil voltage with a 97-ohm coil resistance. It features quick-connect flat blade terminals for easy wiring and a diode across the coil for suppression of voltage spikes, protecting sensitive control electronics. The relay operates reliably across an extreme ambient temperature range from -40°C to +125°C.

With typical operating and release times of 9ms and 7ms respectively, it provides swift and responsive control. Its compact dimensions of 23.5mm x 15.7mm x 26.0mm (L x W x H) allow for installation in space-constrained applications.

This durable relay is an essential component for automotive electricians, vehicle modifiers, and industrial control system builders seeking a dependable, high-capacity switching device.
