Introduction: In an Atex zone it is important to detect objects in a safe way, for example on a conveyor. Customers now often choose to keep running the conveyors continuously in an Atex environment. By applying certified sensors, which carry out a presence detection (in an Atex zone), this is no longer required. This increases the lifespan, decreases the power consumption and reduces the maintenance costs.
In this case, a BX04 area sensor is the perfect solution. Due to the high switching frequency, this lightcurtain, with a range of 2 meters, is capable to detect presence and count passing objects. The sensors are usable for: Ex zones 1, 2, 21, and 22. If the distances are bigger, Ex lasers could be applied to solve this. For example the SP LAM 50 Ex d and the SP LAM 300 Ex d. These lasers have robust stainless steel housing and are suited for Atex zones: 1, 2, 21 and 22.
