GEMÜ 1235Electrical position indicator

Features• Communication and programming interface IO-Link• Adjustable switch point tolerances• Speed-AP function for fast mounting and initialisation• High visibility position indicator by LED• Can be fitted to GEMÜ valves or third-party actuators• On-site or remote end position programming via programming

input

DescriptionThe GEMÜ 1235 electrical position indicator is suitable for mounting to pneumatically operated linear actuators. Secure connec-tion to valve spindle means reliable feedback signal. Intelligent microprocessor controlled functions make commissioning andsupport during operation easier. The current position of the valve is displayed via high visibility LEDs and fed back via electricalsignals. The GEMÜ 1235 has been specially designed for valves with a stroke of 2,0 to 74,4 mm.

Technical specifications• Ambient temperature: -10 to 70 °C• Stroke: 2,0 to 74,4 mm• Communication modes: 24 V | 24 V with IO-Link |• Protection class: IP 67
