IO Signal Output NPN-NO: High-level signal output when powered, and turns to Low-level signal output when Triggered NPN-NC: Low-level signal output when powered, and turns to High-level signal output when Triggered Q & A (keep updating...) Q1: Why the accuracy not as advertised? A1: the accuracy is true, to reach high accuracy, please ensure everything is prepared, like adjusting the concentricity, and the parts/ tools that may affect the accuracy are more sensitive than the touch probe. Q2: Does this touch probe work for the non-conductive material like acrylic? A2: This is a mechanical probe, it identifies and transmits the signal by physical contact, do not worry about the conductivity of the material. Q3: why i can not measure the probe height by tool setter? A3: when it works with other tools, like tool setter, please ensure the sensitivity of the tool setter is higher than this edge finder (trigger force less than 1.6 N). Latest Update Q4: Can the concentricity be adjusted? A4: yes, there are 4 silver set screws on the sides for concentricity adjustment. Note 1 : Use the 0.001" Dial Indicator Adjusting the Concentricity (Not the 0.0001" Dial Indicator) Note 2: Let the Dial Indicator Point to the Ball Styuls of the Touch Probe, Not the Body of the Touch Probe. Q5: Why the probe tip isn’t perfectly straight with the body? A5: it may be caused due to violent shipping or over-triggering, you can correct it by adjusting the concentricity by the set screws. if the tip was bent, you need to replace the tip and then adjust the concentricity. 2 versions (NPN-NO & NPN-NC) of touch probe are available to choose The 3 pcs quick connector pack was equipped for wiring convenient Watch Out for the 4th Q&A on the Left/ Top to Properly Adjust the Concentricity.

It works flawlessly on my CNC machine, making edge-finding and digitizing super easy. The tungsten steel ball tip feels durable, and the build quality is excellent. The wiring was straightforward, and the response is fast and accurate. Overall, a great product for the price! ### ⭐⭐⭐⭐⭐ The ability to probe non-conducted materials is extremely important in my particular work *by R***C on March 15, 2026* One of the very few probes that can probe non-conductor materials worked great ### ⭐⭐⭐⭐ N.O. is V+ when static, 0V when triggered by the edge. *by V***Y on December 16, 2023* Their definition of NO / NC seems backwards to me. It seems like NO should be 0V at rest but it's not. Instead, at rest the yellow lead is high (12V or whatever your power supply is) and it goes low when triggered by an edge. Fortunately my CNC control has both a normal and an inverted probe input so I didn't have to exchange this. This NO probe would not work in this control's edge finder port as it requires trigger=high. Once wired correctly the probe works very well. I checked runout after placing in a standard ER20 Tormach TS tool holder and TIR of the probe tip was 0.0005 out of the box before making any adjustments. ## Frequently Bought Together - PGFUN DIY CNC Touch Probe XYZ Axis 3D Digitizing Edge Finder 3-Coordinate Measuring Sensor Kit with 6 mm Shank & 2.0 mm Tungsten Steel Ball Tip - Z Axis Automatic Tool Setter Modifying Kit for PGFUN CNC 3D Touch Probe Edge Finder Contactor --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/459226748-diy-cnc-touch-probe-xyz-axis-3d-digitizing-edge-finder](https://www.desertcart.co.uk/products/459226748-diy-cnc-touch-probe-xyz-axis-3d-digitizing-edge-finder) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
