Position-sensing, position-indicating solid-state, tie-rod-mounted limit switch for hydraulic cylinders detects a polarity change in standard steel tubes as the magnetic piston moves through the cylinder. Two LEDs (yellow and red) indicate whether magnet is inside or outside of the switch target zone. It is designed for use on 1.5 to 4-in. bore series 2H, 3L, and 2A cylinders. It is available in PNP and NPN outputs.
