Explosionproof Strobe lights dSLB 20 series for Zone 1, 2, 21, 22 |
Robust optical signalling device for use in areas with explosive atmospheres in group II and zones 1 and 21 |
|
Application |
It is often necessary to use optical signals for warning, indicating and signalling purposes in areas with explosive atmospheres. The ExII strobe light dSLB 20 series offers these signalling possibilities. It is designed for continuous operation. The dSLB 20 series strobe light is activated by switching on the power supply and is available with various rated voltages. The sturdy housing conforms to protection degree IP 66/67 and can be installed both indoors and outdoors. |
|
Design |
The ExII strobe light consists of a small flameproof housing of aluminium containing the electronics and a glass cap of hardened borosilicate glass. The terminal enclosure is realised in the explosion protection mode "in creased safety". To built up a signalling combination please use the mounting plate, made by V4A, with integrated junction box from the accessories. |
