Amperite L-WIG-WIRE relays, such as the LW-121, are miniature, all-welded pc board-mounting relays commonly used to control applications such as remote sensing, instrumentation, motor control, and telecommunications. These relays utilize an arc-resistant, low profile, Wound International (WIG) form and feature high-melting temperature wire. As the relay is all-welded, they can be used in environments with extreme vibration, shock, or temperature changes. The LW-121 is rated for 10A, 250VAC and 125/250VDC operation and is UL approved.
