It uses a 1\/4\" PT sensing port and supports multiple switching configurations, including hysteresis and window comparator modes, with an added peak\/bottom hold function for stable monitoring. The -27L variant provides an NPN open-collector output powered from a 12–24 VDC supply and can sink up to 80 mA, with typical wiring of Brown (+), Blue (−), and Black (output). Inside, the pressure sensor is SUS630, mounted in a PBT body with a PPO indicator panel and NBR seals for durability in industrial environments. This model is well-suited for vacuum-pump control and vacuum-system monitoring within manufacturing equipment, offering precise, repeatable switching at set vacuum thresholds and seamless integration with the ZSE5B family for consistent automation across systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"SMC","offers":[{"title":"New","offer_id":46260407861482,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-015.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/smc-corporation-zse5b-02-27l-vacuum-pressure-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
