Panasonic Signal Relay Distributor | TQ Series Relays

BeiLuo supplies genuine Panasonic signal relays, the small, sealed relays that switch low-level signals in instrumentation, communications, security and medical equipment. A signal relay must switch a tiny current reliably without distorting it, so the contact material and the thermal electromotive force matter as much as the switching capacity. The Panasonic TQ series is a low-profile relay only about 5 mm high, with a 2 Form C (DPDT) contact arrangement and gold-clad contacts that keep the contact resistance stable over the life of the product. It is available in single-side-stable and latching versions, in through-hole and surface-mount terminals, and with nominal coil voltages from 1.5 V to 48 V, so a designer can match the coil to the available logic supply. The sealed construction allows automatic board cleaning and protects the contacts in a humid or dusty environment, and the low thermal electromotive force, about 5 microvolts for the through-hole version and 2 microvolts for the surface-mount version, makes the relay suitable for precision measurement where a thermal voltage would corrupt the signal. Typical uses include test and measurement, data communication, security systems and medical instruments, and the surface-mount version suits a compact automated assembly. BeiLuo holds mainstream TQ ratings in stock and ships every relay with an import declaration, a certificate of origin and a RoHS file, and our FAE team helps with the coil, contact and terminal selection for the application.
