It supports a wide DC voltage range (6-36V) and delivers a fast 100Hz response frequency. Designed for industrial automation, it offers silent, reliable, and precise non-contact detection with a robust NPN normally open output, making it ideal for advanced control systems. ## Description It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal. As it is capacitive type proximity switch, its detecting object target is not limited to only conductor, but also liquid and even powder things, like plastic, water, glass, oil, etc. It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect. Product Name : Capacitive Proximity Switch;Switch Appearance Type : Cylinder Type Theory : Capacitance Sensor;Output Type : NPN NO(Normal Open);Diameter of Head : 18mm;Detecting Distance : 1-10mm Detecting Object : Metal or Nonmetal Material;Supply Voltage : DC 6-36V;Current Output : 300mA;Response Frequency : 100Hz Size : 7.5 x 4cm/3'' x 1.6'' (L*Max. Dia);Material : Plastic, Alloy Review: Miss conception but works great! - Output 300ma made my head scratch, Normally open and had 12 volts on lead and when closed dropped to zero. seemed reverse. Plus it said output is 300ma. I figured it out, I have a 12volt relay with 25ma trigger coil. I put 12volts lead to + side of coil and then negative goes to output lead and it works great. The proximity sensor is designed to be the ground point not the source for relays. just reverse your concept of powering the relay. All is working very well. Sensitivity is excellent as well. I can get upto 3/4" on very capacitive devices now. Review: Works great on my Modded Monoprice Select Mini V2 - Tried the BL touch style, ended up returning it due to terrible inconsistent sensing. Got one of these and a BAT85 diode (killed a board without one. A 20$ lesson). I have had some of the best 1st layers ever with this thing, even with a 4mm glass bed. I modded my printer to be super quiet. The BL Touch style probes make soooo much noise when you have a quiet printer. These sensors are completely quiet. They do have a long sensing distance, but you get the best accuracy if you set it as low as possible. ## Features - Special attention: After the switch is installed, the sensing distance needs to be adjusted, otherwise, there will be no response when the switch is turned on.There are two friends recently. The reaction product does not work, First note: our products are 100 % tested before they leave the factory. Solution: 1. Turn Switch control sensing distance behind the product; 2 .Send us an email and we will send you a new one. - Product Name : Capacitive Proximity Switch; Model : LJC18A3-H-Z/BX;Wire Type : DC 3 Wire Type (Brown, Black, Blue);Theory : Capacitance Sensor; Output Type : NPN NO(Normal Open);Diameter of Head : 16mm; Thread Diameter:18mm; Detecting Distance : 1-10mm - Operating Temperature : -25 to +65 Celsius (Non-freezing Condition);Size : 7.5 x 3cm / 3"x 1.2"(L*Max.

Or do I need an intermediate relay?** A: You will need a relay. It will not provide enough current to run a motor. **Q: Only works when I touch the metal body of the switch, then the light comes on and sensor works. Is it defective?** A: Check your ground and make sure the power supply is on a separate circuit from all other devices and not on common ground. This Prox switch is sensitive to electronic noise interference. **Q: Is it waterproof?** A: Maybe but I don't suggest using near liquids ## Customer Reviews ### ⭐⭐⭐⭐⭐ Miss conception but works great! *by S***N on March 22, 2021* Output 300ma made my head scratch, Normally open and had 12 volts on lead and when closed dropped to zero. seemed reverse.

Tried it on a 3d printer and I could not get it to work accurately for the Z axis. Problem was that it was not repeatable. I am using this at 24 v and it works well for my Y position. ## Frequently Bought Together - Taiss LJC18A3-H-Z/BX Proximity Switch 1-10mm Sensor Switch Capacitance Proximity Sensor Switch NPN NO（Normally Open） DC 6-36V 300mA M18 3-Wire - Twidec/M12 Approach Sensor Inductive Proximity Switch PNP NO DC 6-36V, 4mm Detecting Distance LJ12A3-4-Z/BY - Taiss 2PCS LJ12A3-4-Z/BX Proximity Switch 3D Printer Inductive Proximity Sensor Detection Switch NPN NO DC6-36V 4mm Normally Open --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/47094247-taiss-ljc18a3-h-z-bx-proximity-switch-1-10mm-sensor](https://www.desertcart.tn/products/47094247-taiss-ljc18a3-h-z-bx-proximity-switch-1-10mm-sensor) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-09*
