TE Connectivity has launched a power
PCB relay for heating, ventilation, and air conditioning (HVAC) and other
industrial control applications. The new relay operating at 30 A is part of the
Potter & Brumfield T9G series; it boasts quick-connect terminations, and
that makes the relay user-friendly and easy to install.


claims that its new PCB relay offers 30% smaller package size and 13%
less PCB floor space than competing products.
That, in turn, allows manufacturers to add more components on PCBs without having
to compromise on relay performance.

PCB relay also complies with the IEC 61810-1 standard to reinforce
insulation amid an increase in distance between coil and contacts. Furthermore, it features a rating of 4
kV between coil and contact to provide better galvanic isolation.

Next, to ensure that surge
resistance can withstand voltage, the T9G series relays have an 8-kV
rating and thus can provide a higher degree of circuit protection. The relays
also use a 900-mW coil that facilitates a 10% power reduction as compared to the
conventional 1-W power PCB relays.
