The device outputs quadrature signals with an index (A, B, Z) for high-resolution position and speed measurement, enabling reliable closed-loop control when paired with BEI's or compatible servo and PLC systems; the SM18 variant indicates the specific wiring\/connector configuration used for this model, which is part of BEI's XH20 family known for high resolution and compact form factors. With 600 PPR resolution and optical sensing, this encoder provides fine-grained feedback for precise motor control, making it suitable for CNC machining, robotics, conveyors, and other applications where accurate incremental position data is essential, while 28-volt operation and the 3\/8-inch shaft support straightforward integration into a wide range of industrial motion systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"BEI","offers":[{"title":"New","offer_id":51676829253934,"sku":null,"price":616.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_81055476-b75d-4660-892c-1d6f75053bf9.jpg?v=1769553997","url":"https:\/\/plgautomation.com\/products\/bei-sensors-xh20db-37-ss-600-abzc-28v-sm18-rotary-encoder","provider":"PLG Automation ","version":"1.0","type":"link"}
