LJ18A3-8-Z/BX M18 8mm sensing DC 6-36V NPN NO cylinder inductive proximity sensor switch

From the shop's description

This Tube Type Inductive Proximity Sensor Detection Switch NPN DC6-36V 4mm Normally Open switch LJ18A3-8-Z/BX is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. When the proximity switch is close to some target object, it will send out control signal. When the metal approaches near-proximity switch sensing area, an Edy Current is induced in metal. Which in turn disturbs the magnetic field produced by the Inductive Proximity Sensor. This change is sensed by the sensor. This inductive proximity switches can be non-contact, no pressure, no spark, quickly issued the electrical command. Accurately reflect the position and the stroke movement mechanism. Positioning accuracy, operating frequency, service life. Easy to install and suitable for harsh environments. This 4mm proximity sensor can detect a variety of metals, miniature size, long life, low price, shielded type installation, anti-interference ability, 1mm detection distance, using for precise positioning of molds, precision machine tools, and robots. Features of LJ18A3-8-Z/BX : Red LED checks the state of the proximity sensor High repeated positioning accuracy High switching frequency Wide voltage range Outer (Theard) Diameter: M18 Antivibration, dust, water and oil prevention Reverse power protection, short circuit protection, directly connecting with PLC Can replace small switches and limit switches Package Includes : 1 x DC 6-36V M18 Inductive 8mm NPN-NO Proximity Sensor Switch Model number LJ18A3-8 series External dimensions M18x1x68 Installation type Non-shielded Detection distance 8mm, 15mm, 20mm Setting distance 6.4 mm Supply voltage 6-36Vdc; 90-250Vac, 36Vac, 380Vac, 50/60Hz Output current DC type: 300mA max; AC Type: 400mA Standard detected object Mild steel (18x18x1mm) Sensing object Magnetic metals (if it is not magnetic metals, the sensing distance would decrease) Response frequency 500Hz Matched mounting bracket M18 90° bending mounting bracket, M18 straight mounting bracket Output indication Red LED Short-circuit protection No Reverse connection protection Yes Insulation resistance 50MΩ min (between charging part and housing) Dielectric strength 1000Vac, 1min (between charging part and housing) IP Rating IP65 Operating temperature -25 to 70 ℃ (13 to 158 ℉) Cable length 1.2m, PVC cable Material Case: Brass-nickel plated; Sensing surface: ABS Alias name LJ18A3-8 series cylinder inductive proximity switches
