TXS2SA-L2-4.5V is an ultra high sensitivity 2 coil latching signal relay from the Panasonic TX-S series, featuring a nominal coil voltage of 4.5V DC and surface-mount terminal (SA type). It offers a 2 Form C contact arrangement with gold-clad twin crossbar contacts (Ag+Au clad) for high contact reliability, and achieves a nominal operating power of 70 mW for the 2 coil latching configuration. The relay features compact dimensions of 15.0 × 7.4 × 8.2 mm, a maximum switching power of 30 W DC with resistive load, and a maximum switching current of 1 A. With outstanding surge resistance (1,500 V surge breakdown voltage between open contacts), an operating temperature range of -40°C to +70°C, and RoHS compliance, this relay is well-suited for telecommunications, signal switching, and other applications requiring low power consumption and high contact reliability.
