TXS2SA-9V is a single-side stable electromagnetic relay designed for low-power switching applications with a nominal coil voltage of 9V DC. The relay achieves ultra-high sensitivity at 50 mW nominal operating power through a highly efficient polar magnetic circuit with seesaw balance mechanism, delivering a minimum operating power of 32 mW. It features 2 Form C contacts with gold-clad twin crossbar contacts for high contact reliability, maximum initial contact resistance of 100 mO, and a nominal switching capacity of 30V DC at 1A resistive load. The compact surface-mount design measures 15.0 mm × 7.4 mm × 8.2 mm, with outstanding surge resistance rated at 1,500V (10×160 µs) between open contacts per FCC Part 68. This relay is ideal for telecommunications, automotive control systems, and low-power switching applications requiring high reliability and compact form factor.
