Featuring 0.001mm positioning accuracy, a durable dustproof and waterproof housing, and a reliable DC24V 20mA output, it ensures precise tool length setting, wear detection, and breakage alerts. Its robust construction and smart alarm system make it an essential upgrade for professional CNC operators seeking flawless performance and reduced downtime. ## Description RATTMMOTOR Normally Closed Mach3 CNC Automatic Tool Sensor | Gauge Changer CNC Z Axis Probe Tool Touch Sensor Setter Setting 4 Wires for CNC Router Engraver Machine: desertcart.com: Industrial & Scientific ## Features - 【Description】The tool setting instrument is a special tool setting instrument for the engraving machine machining center machine. The output signal of the tool setting instrument is received by the numerical control system and then the tool length setting, tool wear detection and tool breakage are detected by the program control. In the case of no vibration and malfunction, the thermal deformation of the machine can be corrected according to the rated voltage and current and the specified speed. - 【Parameter】This is a normally closed 4-wire high-precision tool setting instrument with a stroke of 5mm. The positioning accuracy is 0.001mm, the contact life is up to 3 million times, the contact force is 1.5N, and the contact rating: DC24V 20mA. - 【Material】The housing material of this tool setter is made of 4S grinding grade material. The bottom magnet design can be directly connected to the machine and firmly adsorbed to the body. The contact material is made of super hard alloy, the design is exquisite and the installation is simple. - 【Feature-1】This tool setting instrument is designed with dustproof and waterproof structure, which can still have strong durability under the condition of coolant and iron filings. It does not need a built-in amplifier and will not be caused deviations by the location temperature and power supply voltage fluctuations of the tool setting instrument, which can be directly input to the NC program. - 【Feature-2】The tool setter will send out an alarm signal in time when it is over-travel to avoid other troubles caused by equipment operation. Moreover, the tool setter has strong anti-interference. The protruding sharp corner of the tool directly touches the tool tip related to the machining size, detects its value and size, and outputs the signal. It has higher accuracy than the average value obtained by converting the amount of light and electricity. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08LK93NTC | | Brand Name | RATTMMOTOR | | Current Rating | 20 milliamps | | Customer Reviews | 3.6 3.6 out of 5 stars (35) | | Global Trade Identification Number | 00713721466467 | | Item Dimensions | 5.91 x 2.76 x 4.33 inches | | Item Highlight | Gauge Changer CNC Z Axis Probe Tool Touch Sensor Setter Setting 4 Wires for CNC Router Engraver Machine | | Item Weight | 0.45 kg | | Manufacturer | RTM | | Material Type | Aluminum | | Maximum Supply Voltage | 24 volts_of_direct_current | | Measurement Accuracy | 0.0001% | | Model | H:65 | | Mounting Type | Surface Mount | | Number of Items | 1 | | Number of Packs | 1 | | Output Type | Push-Pull | | Part Number | H:65 | | Sensing Distance | 5 millimeters | | Style Name | Modern | | UPC | 713721466467 619191755172 769135849716 | | Unit Count | 1 Count | | Upper Temperature Rating | 100 °C | ## Product Details - **Brand:** RATTMMOTOR - **Item Weight:** 0.45 kg - **Item dimensions L x W x H:** 5.91 x 2.76 x 4.33 inches - **Material:** Aluminum - **Style:** Modern ## Images ![RATTMMOTOR Normally Closed Mach3 CNC Automatic Tool Sensor - Image 1](https://m.media-amazon.com/images/I/41mZj2+fbAL.jpg) ![RATTMMOTOR Normally Closed Mach3 CNC Automatic Tool Sensor - Image 2](https://m.media-amazon.com/images/I/51gOO8B-aAL.jpg) ![RATTMMOTOR Normally Closed Mach3 CNC Automatic Tool Sensor - Image 3](https://m.media-amazon.com/images/I/415t-dx7r+L.jpg) ![RATTMMOTOR Normally Closed Mach3 CNC Automatic Tool Sensor - Image 4](https://m.media-amazon.com/images/I/51m-IXTF2vL.jpg) ![RATTMMOTOR Normally Closed Mach3 CNC Automatic Tool Sensor - Image 5](https://m.media-amazon.com/images/I/51skbV5Aa6L.jpg) ## Frequently Bought Together - RATTMMOTOR Normally Open Mach3 CNC Automatic Tool Sensor Gauge Changer CNC Z Axis Probe Tool Touch Sensor Setter Setting 4 Wires for CNC Router Engraver Machine - 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 --- ## 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.nl/products/255990065-rattmmotor-normally-closed-mach3-cnc-automatic-tool-sensor](https://www.desertcart.nl/products/255990065-rattmmotor-normally-closed-mach3-cnc-automatic-tool-sensor) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-09-18*
