1)500bar Pressure Resistant 2)IP68 Protection, Water-Proof and Oil-Proof 3)Full Steel Housing with M12 & M14 diameter 4)CE, UL, RoHS Spool Position Sensor for Hydraulic Directional Valve Relief Valve SENSONG offers integral spool position sensor for selected hydraulic valves. They are known for proven reliability in the field and are a cost-effective way to add sensing capability to a hydraulic control valve circuit. This sensing element is compatible with two-position, on/off solenoid hydraulic relief valves or Hydraulic Directional Valve. It can be specified with both normally open and normally closed valve models. Advantages of inductive proximity sensor 1. Using self-developed special IC improve anti-jamming performance 2. Built-in power reverse connection protection circuit (DC3 wire) 3. Long life, high reliability, economic and simple operation 4. Yellow / Red LED can confirm the proximity switch working state 5. IP67 degree of protection (IEC) specifications 6. Widely used alternative micro switch and the limit switch Housing Size Φ39x96mm Sensing Distance & Mounting 11mm (Flush) Housing Material Nickel plated steel With LED Yes Operating Voltage 10-30VDC Ripple
