The lightweight explosion-proof industrial telephone dA24 is designed for potentially explosive areas. It can be used as an extension telephone and terminal device as well as for multi-frequency or pulse dialing. If the ambient noise is louder, you have the option of switching on an integrated hearing amplifier. An infinitely adjustable holder secures the receiver in the event of shocks. The robust 16-part keyboard is also available with illuminated keys. Upon request, we can supply you with the dA24 with up to two special keys that you can assign additional functions to.
