The **M6SWVS-H6-R/Q** is a high-precision, industrial-grade mechanical limit switch, typically manufactured by **Metrol**. It is widely used in CNC machines, robotics, and semiconductor manufacturing for positioning and touch-sensing applications. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the M6 series, here are the primary electronic and physical specifications: | Feature | Specification | | :--- | :--- | | **Contact Type** | Normally Closed (NC) - Standard for safety circuits | | **Repeatability** | 0.001 mm (1 micron) | | **Output Signal** | Contact Point (Switching) | | **Pre-travel** | 0.3 mm to 0.5 mm (typical) | | **Contact Life** | 10 million operations | | **Protection Rating** | IP67 (Waterproof and Oil-resistant) | | **Housing Material** | Stainless Steel | --- ### 2. Breakdown of the Model Name The alphanumeric code describes the specific configuration of the part: * **M6**: Refers to the outer diameter of the switch body (Metric 6mm thread). * **S**: Indicates a "Slim" or "Small" form factor. * **W**: Represents "Waterproof" (IP67) capability, suitable for environments with coolant. * **VS**: Specifies the stroke type or internal mechanism (Varied Stroke/Precision). * **H6**: Often refers to the contact tip shape or the cable exit direction. * **R/Q**: Indicates specific connector types or cable variants (e.g., Robot cable or Quick-disconnect). --- ### 3. Electronic Characteristics Unlike standard microswitches, the M6SWVS series is designed for **low-current signals**. 1. **Switching Voltage:** Typically rated for 5V to 24V DC. 2. **Current Rating:** Usually very low (around 10mA). It is not designed to drive a load directly; it should be connected to a PLC (Programmable Logic Controller) or a CNC Controller input. 3. **No Hysteresis:** Because it uses a high-precision mechanical contact rather than an inductive sensor, there is virtually no "dead zone" between the trigger point and the reset point. --- ### 4. Common Applications * **Tool Length Offsetting:** Measuring the length of drill bits or end mills in CNC machines. * **Origin Positioning:** Setting the "Home" position for high-accuracy axes. * **Thickness Measurement:** Detecting the height of a workpiece in an automated assembly line. ---
