GEMÜ 1231Electrical position indicator ATEX
Features• Position feedback via 2-wire proximity switch (NAMUR)• Adjustable switch point tolerances via threaded spindle• Can be fitted to GEMÜ valves or third-party actuators• Explosion protection for zone 1 and 21
DescriptionThe GEMÜ 1231 electrical position indicator is suitable for mounting to pneumatically operated linear actuators. The positionof the valve spindle is reliably electronically detected and reported via proximity switches through play-free and non-positivemounting. GEMÜ 1231 has been designed specially for valves with a stroke of 2 to 20 mm .
Technical specifications• Ambient temperature: -20 to 60 °C• Stroke: 2 to 20 mm• Switch type: 2-wire proximity switch• Protection class: IP 65• Electrical connection type: M16 cable gland | M12 connector

GEMÜ CONEXOThe interaction of valve components that are equipped with RFID chips and an associated IT infrastructure actively increaseprocess reliability.
Thanks to serialization, every valve and every relevant valve component such as the body, actuator or diaphragm, and evenautomation components, can be clearly traced and read using the CONEXO pen RFID reader. The CONEXO app, which can beinstalled on mobile devices, not only facilitates and improves the "installation qualification" process, but also makes the main-tenance process much more transparent and easier to document. The app actively guides the maintenance technician throughthe maintenance schedule and directly provides him with all the information assigned to the valve, such as test reports, testingdocumentation and maintenance histories. The CONEXO portal acts as a central element, helping to collect, manage and pro-cess all data.
