It provides a plunger actuation control with a 2 NC\/1 NO contact configuration, housed in a compact aluminum die-cast enclosure measuring 108 x 40 x 42 mm. The unit carries an IP65 rating for dust and water protection, operates over a wide -30 to 80°C range, and uses a wiring chamber for field connections. The primary housing material is aluminum die-cast, and the device features Cat 4 safety category and a SIL CL 3 safety rating, aligning with safety system requirements when properly interfaced with a compatible controller. Mechanical life is specified at 1 million operations, reflecting suitability for recurring actuation in industrial environments. Banner lists this model as obsolete, and advises contacting Banner for information about a suitable replacement. As part of the SI-LM40 series, the SI-LM40PBF is designed for interlocking and position-monitoring tasks such as guarding doors or guards on machinery, where a compact, integrated switch-and-actuator assembly helps simplify installation and wiring while supporting standard safety interlock architectures.\u003c\/p\u003e\u003c\/div\u003e","brand":"BANNER","offers":[{"title":"New","offer_id":51676523233582,"sku":null,"price":246.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_21b05fbf-e978-4dfe-924c-385a5b555a1f.jpg?v=1769551494","url":"https:\/\/plgautomation.com\/products\/banner-engineering-si-lm40pbf-safety-limit-switch-actuator-plunger","provider":"PLG Automation ","version":"1.0","type":"link"}
