Enabling Switch Accept-B with Handle Bar ZB1

The B-COMMAND enabling switch ZB1 is a 3-stage (off/on/off) enabling switch which can ideally be used as an enabling switch in hazardous areas. The housing of the ZB1 was specially developed for long-term use and impresses with its ergonomic housing shape.

The 2 working contacts of the integrated enabling switch are changeover contacts, which offer the customer several possibilities for wiring. The redundant contact configuration fulfils safety category 4.

In addition to the actual enabling switch, a pushbutton or an emergency stop switch can be mounted at the top of the housing. For mounting, we offer an optional wall bracket. The cable entry is made from below by means of a spiral cable gland.

For optimum operating convenience, the actuating force from position 2 to 3 for the centric and eccentric pressure is absolutely identical: even switching with just one finger at the outer end is reliably possible.

In addition, the B-COMMAND enabling switch ZB1 can be equipped with an auxiliary contact (break contact), which can be used for monitoring purposes. In addition to the standard colour yellow, we can also supply the enabling switch ZB1 with a grey or black rubber cap. For applications in the automotive sector, our enabling switch rubber caps are also available in silicone-free material.

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 in the design. In the event of a panic action / 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 actuated and held. It is mainly used when setting up or servicing machines or robots within hazardous areas.
