Feature: 1. MAIN APPLICATIONS: Hall sensor is suitable for pneumatic, hydraulic, cylinder and piston position determination, can also be used for limit closure 2. ADVANTAGES COMPARED WITH INDUCTIVE SENSORS: Inductive proximity sensor switch can be installed in metal, and can be installed closely side by side, can be detected through metal 3. USING NOTE: The distance is affected by the strength of the magnetic field and the approach direction of the detected object. Note the choice of magnetic field polarity S or N pole 4. WORKING PRINCIPLE: When the magnetic wood plaque approach, produce Hall effect, amplified and output switching signal 5. 5PCS IN TOTAL: The package contain a total of 5pcs inductive proximity sensor switch, enough for you to replace and use, very convenient Specification: Item Type: Inductive Proximity Sensor Switch Control Output: ≤100mA Induction Distance: Approx. 10mm / 0.39in Power Supply Voltage: DC5-30V Rated Current: 50MA Response Frequency: ≥2KHz Working Environment Temperature: -20℃~80℃. Package List: 5 x Inductive Proximity Sensor Switch
