Need a reliable sensor for your automation projects? This Woljay capacitive proximity sensor is a workhorse. It's the LJC12A3-5-Z/BX model, a 3-wire DC type (wires are black, brown, blue) with NPN normally open (NO) output. Runs on 6-36V DC and can handle up to 300mA current. The detecting distance is 5mm, and the sensor itself has a 12mm diameter cylindrical shape. Perfect for non-contact detection of objects—think counting, positioning, limit switching, or speed monitoring in machinery, packaging, or light industrial setups. It's widely used because it's durable and accurate. Just wire it up according to the color code, mount it, and it's ready to go. Helps improve efficiency and automation in your projects. A must-have for DIYers, engineers, or small workshops. Check your voltage and wiring before installing. Solid performance at a good price.
