This document introduces the features of a solenoid valve, including rated voltage, rated current, coil power and coil resistance.
The TX Automotive Relay series offers single‑coil (TX1) and twin‑coil (TX2) designs for bi‑directional control of automobile motors. Features include high‑power miniature construction, 30 A switching capacity, and a sealed case suitable for immersion cleaning.
Technical specifications cover coil resistance, contact arrangement (DPDT, Form C), rated load, switching current, dielectric strength, operating temperature, vibration and shock resistance, and mechanical life. Ordering details list part numbers, coil ratings, contact materials, and terminal configurations.
