3-position enabling switch Zustimmtaster Handgriff / Enabling Switch Handheld B-COMMAND

AC/DC

The B-COMMAND enabling switch ZA5 is a three-stage (OFF-ON-OFF) enabling switch, which is ideal for installation on input devices such as our pendant station series Lady. The enabling switch ZA5 has an installation dimension of Ø16mm. It is mounted by a lock nut, which is also used to secure the anti-rotation protection. The two working contacts are change-over contacts, which offer the customer several wiring options. The redundant contact configuration meets safety category four. For optimum operating comfort, the actuation force from position 2 to 3 for centric and eccentric pressure is absolutely identical. The B-COMMAND enabling switches ZA5 are available with or without rubber caps. In addition to the standard rubber cap color yellow, the enabling switch ZA3 is also available with grey or black rubber cap. To enable the use of B-COMMAND enabling switches in the automotive industry, our enabling switches are also available in silicone-free material. 3-Stage Operation Enabling Switches (IEC 60947-5-8) The function of our enabling switches is 3-stage or based on 3 positions. The working contacts are actuated in the middle position. For this purpose, we have implemented a clearly noticeable pressure point on the design side. In the event of panic / injury, the operator would either press firmly (3rd stage) or release the handle (1st stage). Both times the working contacts would be deactivated and the system would be stopped. The 2nd stage must therefore be actively operated and held. It is mainly used for setting up or maintaining machines or robots within hazardous areas.
