Sirius Act is a line of 22-mm IEC pushbuttons, indicator lights and selector switches. Four designs and various options are available for combining actuator and indicator, material, color, type of front ring and lighting. The pushbuttons use a snap-on concept for installation, and installation can be completed with one hand for the actuator, holder and contact block. Visible installation markers and indicators on the components help to reduce the risk of incorrect installation. The devices are IP69K-rated and can be cleaned with a high-pressure jet at high temperatures. The product line provides flexible communication, allowing connection to AS-I, IO-Link and Profinet.
