Connectivity and sensors solutions provider, TE Connectivity (TE), has introduced its new Battery Disconnect Relay 12V (BDR 12V) for automotive high-current applications. The product extends TE's range of high-current (HC) relays that can be used in automotive and industrial applications.

With the BDR 12V relay, TE offers a bi-stable high-current relay specifically for higher current switching. Designed for the increasing number of relay applications with particularly high-power requirements, the Battery Disconnect Relay 12V enables a continuous current of 200A at 85°C.

Jens Waldmueller, Product Manager at TE, said: “Considering that vehicle components have to be smaller and lighter with the same or higher performance, we have succeeded in developing a high-current relay with an outstanding performance-to-space and weight ratio.

“The 50x50x26mm dimensions and weight of 125g enable significant space and weight-saving. Automotive manufacturers who design in the BDR 12V can expect to save up to 20% of space within the battery management module compared to earlier product generations.”

Peak current capability of up to 3,000A and a maximum shock load of up to 150g ensure safe power switching, enabling use in harsh environments.

In addition, vehicle battery disconnection, typical applications of the BDR 12V also include powerful electric heating elements and the switching of motors and pumps. The high current relay is also suitable for start-stop applications.
