The TXS2SA-12V is a surface-mount relay featuring 2 Form C contacts and a nominal coil voltage of 12V DC with 50 mW nominal operating power. This compact relay measures 15.0 mm (L) × 7.4 mm (W) × 8.2 mm (H) and achieves high contact reliability through gold-clad twin crossbar contacts, low-gas formation materials, and mold sealing of the coil section. The relay exhibits outstanding electrical performance with a maximum switching capacity of 1 A at 30 V DC (resistive load), maximum switching voltage of 110 V DC, initial contact resistance of 100 mO maximum, and exceptional surge resistance of 1,500 V (10×160 µs per FCC Part 68) and 2,500 V (2×10 µs per Telcordia). With a nominal operating current of 4.2 mA, coil resistance of 2,880 O, and low thermal electromotive force of approximately 0.3 µV, this relay is ideal for communications, measurement, security, home appliances, audio/visual equipment, and medical device applications requiring reliable switching in space-constrained designs.
