Upgrade your measurement setup with the HEXEH 200mm Aluminum Polyurethane Encoder Wheel! This kit includes two main pieces: a sturdy encoder mounting bracket and a durable 200mm diameter encoder wheel. The wheel is made from aluminum alloy and features a polyurethane tread, offering a good balance of strength and grip. It has a 6mm inner hole and a circumference of 200mm, making it ideal for precise velocity and position measurement when paired with a compatible rotary encoder (like E6B2 OVW TRD types). The mounting bracket is designed to fit encoders with a 20mm diameter and 38-40mm flange size commonly found on the market. The optical axis includes an M8 screw hole, allowing you to extend the shaft length if needed for your specific application. Both the bracket and wheel are built for longevity, with a compact yet robust structure that provides strong support. The overall size of the bracket is about 14x9.4x4.8 cm (5.51x3.70x1.88 inches). This set is versatile – use it in industrial automation, robotics, CNC machinery, or DIY projects where accurate linear measurement is key. The package contains: 1 encoder mounting bracket, 3 fixing screws, 2 locking screws, and 1 encoder wheel. Note: Other encoder components are not included. Colors might vary slightly due to monitors, and sizes have a small allowable error. Need help? HEXEH provides technical support; just email them, and they usually reply within 24 hours.
