It accepts a wide control-supply range of 10.8–264 V DC or 21.6–264 V AC and provides a SPDT relay output with normally open and normally closed contacts via screw-terminal connections. The unit supports light- or dark-switching sensing and offers adjustable sensitivity to suit varying beam strength, part reflectivity, and environmental conditions. Built in a plastic rectangular housing, the PMT20RI carries an IP67 rating for dust and water ingress protection, making it suitable for harsh industrial environments. In operation as the receiver in a through-beam arrangement, it relies on a modulated infrared beam to minimize ambient-light interference, delivering reliable object-detection performance across factory conveyors, machinery gaps, and guarding applications. This model emphasizes long-range detection with a compact form factor, combining wide voltage compatibility, a robust enclosure, and a versatile output to support a range of automation tasks. \u003c\/p\u003e\u003c\/div\u003e","brand":"CARLO","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677696459054,"sku":null,"price":174.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f362fd70-cf08-422f-b05c-4098d88fbefe.jpg?v=1769566592","url":"https:\/\/plgautomation.com\/products\/carlo-gavazzi-pmt20ri-photoelectric-switch-through-beam","provider":"PLG Automation ","version":"1.0","type":"link"}
