Enabling switch Accept-B with handle ZB2
The B-COMMAND enabling switch ZB2 is a 3-stage (Off-On-Off) enabling switch, which can be ideally used as an enabling switch in the hazardous area. The housing of the ZB2 was developed especially for permanent 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 wiring options. The redundant contact configuration fulfils safety category 4.
Optionally, the enabling switch ZB2 can be equipped with an emergency stop mushroom button with two NC contacts. Furthermore, we also offer the enabling switch ZB2 with extra push buttons or key switches. For mounting we offer an optional wall bracket.
For optimum operating convenience, the actuating force from position 2 to 3 is absolutely identical for both centric and eccentric pressure: even switching with only one finger at the outer end is reliably possible.
In addition, the B-COMMAND enabling switch ZB2 can be equipped with an auxiliary contact (normally closed contact), which can be used for additional ones. Besides the standard color yellow, we can also supply the enabling switch ZB2 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.
If you have any questions about our enabling switch ZB2, we are always available by phone, e-mail or live chat.
The functionality of our enabling switches is 3-step or based on 3 positions. The working contacts are actuated in the middle position. For this purpose we have implemented a clearly perceptible pressure point on the design side. In case of 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 thus the system would be stopped. The 2nd stage must therefore be actively operated and held. It is mainly used when setting up or maintaining machines or robots within danger zones.
