Feature:1. [High Accuracy Durable] The proximity switch is of brass and resin, with high accuracy, fast frequency response, strong anti interference ability.2. [Vibration Resistance] The inner cavity of the switch is filled with resin and it is fully enclosed, which is vibration resistance and corrosion resistance.3. [Waterproof Oil Proof] The inductive proximity sensor detection switch also has the characteristic of water resistance, oil resistance and durability.4. [Multifunctional Use] This detecting distance approach sensor can be used to detect objects in various environment, to control the switches.5. [Widely Used] This capacitive proximity switches can not only detect metal, but also detect paper, plastic, water, oil, alcohol, flour, etc.Specification:Item Type: Proximity SwitchMaterial: Brass, ResinRated Working Voltage: AC90-250VBEM12-02-AB Output Mode: AC NC (Normally Closed)BEM12-02-AK Output Mode: AC NO (Normally Open)Installation Method: Non EmbeddedThread Diameter: Approx. 12mm / 0.47inDetection Object: Metal, Paper, Plastic, Water, Oil, Alcohol, Flour, etc.Operating Temperature: -25~70Storage Temperature: -45~80Humidity: <90%Purpose: To Detect Objects in Various Environments, to Control the on and off of Switches.Package List:1 xProximity Switch2 x Gasket2 x NutNote:It is strictly forbidden to power on and wire.
