This variant is designed for external mounting, includes an emergency handle, and is specified for a right-hand door hinge, with the manufacturer article number 101176977. As part of the AZ 3350-STS30 family, it belongs to a line of door-handle actuators (01–08) that provide positive interlock on access doors of industrial equipment. In typical applications, the unit is installed on guarding doors for presses, conveyors, and other machinery where access must be physically blocked while hazards are present and only released when the door is safely closed. The door-handle system integrates mechanical latching with monitored electrical interlocks to ensure a controlled sequence: opening the door disengages the interlock and stops the machine, while closing and actuating the handle re-enables the safety circuit. The AZ 3350-STS30 family is documented across Schmersal’s product portals, reflecting its role in standardizing door-access safety across different door configurations. This specific 05 variant offers external mounting with an emergency handle, making it suitable for right-hinged exterior doors and simplifying retrofit on compatible machines that already use Schmersal AZ 3350 safety switches.\u003c\/p\u003e\u003c\/div\u003e","brand":"SCHMERSAL","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46283996430570,"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\/schmersal-az3350-sts30-05-door-handle-safety-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
