Product Overview
The R. STAHL 8602/3 series actuators are designed for extreme conditions, offering robust performance. They are suitable for use in ambient temperatures ranging from -60 °C to +70 °C, while maintaining an IP66 degree of protection in accordance with EN 60529. A single axial actuator from the 8602/3 series can operate up to four contact elements from the 8082 series. The integrated coding option for key switches and rotary switches allows for easy adjustment of "latching/spring return" and "key not removable" functions without additional accessories. A range of accessories, including label holders and locking devices, is available.
This product is [Explosion Protected] rated.
