Feedrate: 50-200 mm/min. Approach Direction: ±X, ±Y, +Z. Over Travel Protection Distance: X- ± 4mm/0.16 in, Y- ±4mm/ 0.16 in, Z- 2mm/ 0.08 in. Lifetime: > 3 million triggers. Trigger Force: XY- 0.3-0.5 N, Y- 2.7N. Application: theoretically it can work with MACH3, Mach4, Dynamotion, LiNUXCNC, UCCNC, Centroid CNC, or any other CNC control software Package Include: 3D touch probe x 1, cable x 1, allen wrench x 1, probe tip x 1, wire connector pack x 1 (to solve the lack of control board wiring ports and extend wire). Software RecommendationProbe Wizard or ProbeIt are recommended for Mach3, and GRBLGRU is recommended for GRBL. FAQs: Q1: Need to turn on the spindle speed? A1: Please do not, or it may cause measurement error. Q2: Why is the concentricity different when the probe is installed? A2: Because the low-accuracy spring collet can't guarantee 100% positive position. After each installation of the probe, even if the concentricity is adjusted to 10 μm, there will still be deviations when the probe is re-installed. So it is best to use a AAA /UP or higher accuracy ER spring collect (run-out tolerance <0.0002") for your chuck. It is recommended to use a high-precision gauge to check the concentricity after installing the chuck. Q3: i need a NC touch probe, what should i do?A3: we added the NPN-NC touch probe, you can buy the right wiring version for the machine now. Q4: Does this touch probe work for the non-conductive material like acrylic? A4: This is a mechanical probe, it identifies and transmits the signal by physical contact, do not worry about the conductivity of the material. Review: Pretty Good for the price. - I've had this for a year. normally closed version. It mounts in a 6mm collet. In my setup it's dead on in one direction and .0009" in the other. Z is dead on. Interfaces directly with tormach 1100mx. Red to +5, blk to gnd com, yellow to input pin on the 5 pin DIN connector. Review: Very repeatable. - The probe I received was the wrong type. Normally open instead of normally closed. desertcart and the seller refunded me. I was able to modify the PCB by adding a transitor and a bridge wire to convert it to normally closed. Normally closed means that if I forget to plug the probe, or a wire breaks, the CNC controller will think the probe is activated, stopping motion. Instead of the dangerous normally open, where the same scenario would let the machine continue its motion until possible destruction. The probe itself is very repeatable, to within 10μm. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CC5BFFZW | | Batteries Required? | No | | Best Sellers Rank | 235,397 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 73 in Edge Finders | | Customer Reviews | 4.8 4.8 out of 5 stars (9) | | Date First Available | 31 July 2023 | | Item Package Quantity | 1 | | Item Weight | 168 g | | Item model number | TR-0041_NC | | Manufacturer | PGFUN | | Package Dimensions | 12.19 x 7.19 x 7.19 cm; 168 g | | Part number | TR-0041_NC | ## Images ![DIY CNC 3D Digitizing Touch Probe Upgraded NPN-NC XYZ Axis Edge Finder Waterproof 3 Coordinate Measuring Sensor Kit with 6mm Shank - Image 1](https://m.media-amazon.com/images/I/517WnecYX0L.jpg) ![DIY CNC 3D Digitizing Touch Probe Upgraded NPN-NC XYZ Axis Edge Finder Waterproof 3 Coordinate Measuring Sensor Kit with 6mm Shank - Image 2](https://m.media-amazon.com/images/I/71Fd5WLXV4L.jpg) ![DIY CNC 3D Digitizing Touch Probe Upgraded NPN-NC XYZ Axis Edge Finder Waterproof 3 Coordinate Measuring Sensor Kit with 6mm Shank - Image 3](https://m.media-amazon.com/images/I/61i6l1aVSDL.jpg) ![DIY CNC 3D Digitizing Touch Probe Upgraded NPN-NC XYZ Axis Edge Finder Waterproof 3 Coordinate Measuring Sensor Kit with 6mm Shank - Image 4](https://m.media-amazon.com/images/I/61QZitXsN8L.jpg) ![DIY CNC 3D Digitizing Touch Probe Upgraded NPN-NC XYZ Axis Edge Finder Waterproof 3 Coordinate Measuring Sensor Kit with 6mm Shank - Image 5](https://m.media-amazon.com/images/I/7140xfnTiRL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pretty Good for the price. *by M***K on 30 January 2026* I've had this for a year. normally closed version. It mounts in a 6mm collet. In my setup it's dead on in one direction and .0009" in the other. Z is dead on. Interfaces directly with tormach 1100mx. Red to +5, blk to gnd com, yellow to input pin on the 5 pin DIN connector. ### ⭐⭐⭐⭐ Very repeatable. *by B***R on 10 February 2026* The probe I received was the wrong type. Normally open instead of normally closed. Amazon and the seller refunded me. I was able to modify the PCB by adding a transitor and a bridge wire to convert it to normally closed. Normally closed means that if I forget to plug the probe, or a wire breaks, the CNC controller will think the probe is activated, stopping motion. Instead of the dangerous normally open, where the same scenario would let the machine continue its motion until possible destruction. The probe itself is very repeatable, to within 10μm. ### ⭐⭐⭐⭐⭐ caution about the nonstandard cable that comes with the touch probe. *by E***I on 28 April 2025* The product appears to work well. It is apparent that it uses a nonstandard USB type C cable. I tried to make one from a USB type C cable. Power and ground wires were present, but the signal cable did not connect. I am now trying to make a new mail connector with a type USB C breakout board that contains all 24 connections. It would be nice if the seller also provided another custom cable as an available option. I have both a mill and a router that I wish to use it on. Whatever you do, do not try to use a standard USB type C cable. Without modifying it, you will most likely damage your equipment. ## 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 - ER11-6mm UP/AAA Grade Spring Collet .0002" Accuracy for PGFUN 3D Edge Finder CNC Touch Probe (1-Pack) --- ## 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/545611468-diy-cnc-3d-digitizing-touch-probe-upgraded-npn-nc-xyz](https://www.desertcart.tn/products/545611468-diy-cnc-3d-digitizing-touch-probe-upgraded-npn-nc-xyz) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-08*
