TX-S Series Relays

The TX-S Series Signal Relays provide different signal switching circuits by using twin crossbar contacts which ensure high switching reliability. The contacts also come standard with gold plating to reduce the potential of oxidation and silver-palladium (AgPd) for use in low level load analog circuits. Available as a 2FormC contact arrangement, this series offers single side stable as well as either single or double coil latching drive types. The TX-S Series Signal Relays also features surface mount or through-hole terminals and coil voltages which range from 1.5 up to 48V DC.

The TX-S Series Signal Relays feature a high sensitivity coil with a nominal operating power of only 50mW ideal for low power consumption applications. The TX-S Series Relay also has a low thermal electromotive force of approximately 0.3µV.
