It features a solenoid-driven lock with 24 V ac\/dc voltage and a contact configuration of 2 NC and 1 NO plus 1 NC monitor contact, enabling gate monitoring and interlock logic that prevents machine restart if the guard is not securely closed. The compact body measures 170 x 43 x 45 mm with a thermoplastic housing, and it carries an IP67 rating for protection against dust and immersion in water. It operates from -25 to 70 °C and supports safety integrity requirements up to Cat 4, PL e, and SIL CL 3, with an extraction force of 1500 N to resist door opening forces. Electrical ratings include a rated operating current of 4.4 VA and a monitored lock function that helps prevent unintended re-energization due to wiring or switch faults. The SI-LS42DMI belongs to Banner's SI-LS locking interlock family and is designed for integration with Banner safety modules in two-channel safety circuits for gate guarding and machine safety systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676522742062,"sku":null,"price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_7f468174-8ee5-4e3f-9a96-36e8f45acd67.jpg?v=1769551494","url":"https:\/\/plgautomation.com\/products\/banner-engineering-si-ls42dmi-safety-interlock-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
