TE Connectivity – 30A PCB relay saves space in tight board layouts


The Potter & Brumfield T9G series from TE Connectivity (TE) is a 30A PCB-mount power relay.

The T9G is the smallest relay in its class, featuring a 30% smaller package and occupying a 13% smaller board area while keeping an industry-standard footprint.
The relay is available in versions with coil voltage ratings of 5V, 9V, 12V, 15V, 18V, 22V, 24V, 48V and 110V DC. The contact arrangement is either 1 Form A, 1 Form B or 1 Form C.

Isolation between the coil and contacts is high: the relay has a 4kV dielectric rating, and 8kV surge rating.

The T9G has both UL and VDE certifications, which means that it can be designed into applications intended for use anywhere in the world. Offering quick-connect terminations, it is user-friendly and easy to install.
