The CTM variant features an aluminum housing for hazardous-area mounting, is IP66\/67 rated, and is compatible with an ExBox to enable safe installation in Ex environments; it delivers 50 Nm torque and roughly 90° rotation to position dampers and quarter-turn valves in process lines. Control options include three-position operation with position feedback via 0–10 V DC or 4–20 mA signals, and integrated auxiliary switches that report end-of-travel positions; the spring-return mechanism engages when power is removed, ensuring fail-safe closure. ATEX and IECEx certification per directive 2014\/34\/EU for zones 1, 2, 21, 22, along with Schischek’s ExMax documentation, supports use in chemical plants, refineries, and offshore installations that require explosion-protected actuation of dampers and valves. \u003c\/p\u003e\u003c\/div\u003e","brand":"SCHISCHEK","offers":[{"title":"New","offer_id":46284012454122,"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-021.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schischek-gmbh-emax-50-sf-ctm-dc-positioner-atex","provider":"GTG Hardware","version":"1.0","type":"link"}
