This Capacitive Proximity Sensor Switch is engineered to detect a wide array of materials including glass, plastic, water, oil, and wood. It’s the essential choice for Non-Metallic Level Control, object counting, and automated sorting in complex industrial environments.\u003c\/li\u003e\n\u003cli\u003ePrecision PNP Normally Open (NO) Logic: Reliable signaling for your PLC or controller. Operating on a DC 10-30V range with a 300mA output, the PNP normally open 3-wire configuration ensures a clean, fast response. Each unit features a high-visibility LED indicator that provides immediate visual confirmation when a target is within the detection zone.\u003c\/li\u003e\n\u003cli\u003e10mm Adjustable Sensing Distance: Tailor the sensitivity to your specific material. Unlike fixed sensors, the LJC18A3-B-Z features a built-in potentiometer on the rear. This allows you to fine-tune the 10mm Detecting Distance to compensate for different dielectric constants, ensuring stable triggering even for low-density objects.\u003c\/li\u003e\n\u003cli\u003eRugged M18 Industrial Housing: Built for durability in harsh conditions. Protected by an impact-resistant shell, this M18 sensor is designed to withstand vibration and dust. It is widely used as a limit switch in CNC machinery and as an upgraded 3D Printer Bed Leveling sensor for glass or PEI print surfaces.\u003c\/li\u003e\n\u003cli\u003eStable 3-Wire Interference Resistance: Minimize downtime. The high-quality internal circuitry is optimized to resist electromagnetic interference (EMI), preventing false triggers in noisy electrical environments. Whether it’s for a DIY garage project or an industrial assembly line, Wengart delivers the precision your Normally Open 300mA circuits require.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe Smart Choice for Intelligent Non-Contact SensingTraditional inductive sensors fail when it comes to non-metallic materials. The Wengart Capacitive Proximity Sensor Switch LJC18A3-B-Z bridges that gap. By utilizing advanced capacitance technology, this M18 sized switch allows you to detect everything from the water level in a PVC pipe to the presence of a cardboard box on a conveyor belt. It provides a Stable and Reliable sensing solution for both DC 10-30V industrial systems and hobbyist electronics.Fine-Tuning for Professional Accuracy One size does not fit all in automation. That’s why our PNP Normally Open sensor includes an adjustable sensitivity dial. By simply turning the rear potentiometer, you can optimize the 10mm Detecting Distance for the specific dielectric constant of your target material. This feature is critical for 3D Printer enthusiasts who need to calibrate their auto-leveling systems for different bed materials, ensuring a perfect first layer every time.Technical SpecificationsModel: LJC18A3-B-Z\/BYModel: LJC18A3-B-Z\/BYDetection Type: Capacitive (Detects Non-Metallic \u0026amp; Metallic)Detection Type: Capacitive (Detects Non-Metallic \u0026amp; Metallic)Output Type: PNP Normal\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43338750623953,"sku":"BW-B0C4XBNJZF","price":14.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/belmontwarehouse.com\/products\/wengart-ljc18a3-b-z-capacitive-proximity-sensor-switch-m18-pnp-normally-open-no-dc-10-30v-300ma-10mm-adjustable-sensing-distance-for-non-metallic-level-control-3d-printer-bed-leveling","provider":"Belmont Warehouse","version":"1.0","type":"link"}
