The unit features a die-cast aluminium enclosure with a sheet aluminium cover and an IP65 protection rating to VDE 0470 T1, making it suitable for dirty or wet production environments. It provides three cable entries (M20 x 1.5) and a spacious DIN EN 50013–compliant terminal area to simplify wiring and branching in complex control circuits. The SN2-U1 AH actuator is a lever option whose position can be adjusted in 90° increments, with graduated adjustment and a selection of actuators to fit a wide range of applications. The switch uses a galvanically isolated changeover contact (Zb) in SPDT configuration, commonly offered as 1 NC\/1 NO (with other contact configurations available in the SN2 family). Electrical data for related SN2-U1Z AHS variants show a rated insulation voltage up to 400 V AC and a current rating around 10 A, with AC-15 operation at 240 V \/ 3 A; exact ratings depend on the specific sub-model, so the 603-3135-012 variant should be consulted in its datasheet for precise figures. The SN2 line is designed to accommodate slow-action or snap-action contacts and can be configured with different contact-count options (1 NC\/1 NO or 2 NC), enabling it to suit end-of-travel sensing, machine safety interlocks, and other position-detection roles in conveyors, tooling, and other automated equipment. \u003c\/p\u003e\u003c\/div\u003e","brand":"BERNSTEIN","offers":[{"title":"New","offer_id":51676941779246,"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_ac5fef39-71b5-4c1f-b749-9703520939ed.jpg?v=1769555548","url":"https:\/\/plgautomation.com\/products\/bernstein-603-3135-012-limit-switch-sn2-u1-ah","provider":"PLG Automation ","version":"1.0","type":"link"}
