Powered from 10–30 V DC, the receiver provides bipolar outputs (1 NPN and 1 PNP), with a 2 m (6.5 ft) pre-wired cable to connect directly to common PLC inputs and control modules, enabling straightforward integration without external adapters. In this opposed, through-beam configuration, the emitter delivers the infrared beam (around 880 nm) to the receiver, and any interruption in that beam signals the presence or absence of a target within the 3 m sensing zone. The SM31R is ideal for compact object detection on conveyors, packaging lines, and machinery where a small, robust through-beam receiver can provide decisive, contactless sensing signals.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"New","offer_id":51676507570478,"sku":null,"price":68.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9e91d27f-7999-448c-a85e-2d7c9c8153a5.jpg?v=1769551493","url":"https:\/\/plgautomation.com\/products\/banner-engineering-sm31r-photoelectric-mini-beam-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
