STA 1 Series

Our STA 1 operator is optimal for spring-balanced sectional doors. This is ensured by a gear unit developed specifically for this application with a rolled worm shaft and a bronze worm wheel, as well as a special motor that provides a great deal of power in a very tight space. The design of the operators is extremely compact, the housing very slim. The cable sets for connecting the motor and controller feature plug-in connectors. The operators from the STA-I series are available with a standard hollow shaft and, on request, with a special hollow shaft, for example with a diameter of 30.0 mm, 31.75 mm, 35.0 mm. The limit switch is activated by an absolute encoder.
