The new SLB 240/440 range of safety light barriers have built-in analysis and impressively small dimensions. This means the SLB 240/440 with cable connection and dimensions of WHL 28x32x72 mm or with connector socket (WHL 28x32x91 mm) can easily be built into very confined spaces and can be mounted quickly and easily even where space is short. Both models have a range of 15 metres, while the SLB 440-H can achieve a range of up to 75 metres.
The single beam safety light barriers are particularly useful for securing smaller hazard areas, such as machines with small openings or slots, in paper printing machines, for example: This provides reliable protection for the operating personnel, as every interruption to the light beam triggers a signal which safely switches off the potentially hazardous machine movement.
All SLB light barriers have safe semiconductor outputs (2 x PNP) and can be included directly into the safety circuit, even without external safety evaluation. In accordance with IEC 61496, the new product range complies with the requirements for all Type 2 or Type 4 applications. They are then used for process protection, for example in high-shelf warehouses, where deviations from pre-defined positions are detected by means of object recognition and height recording, thus preventing collisions and damage.
The SLB 440-H version, which can monitor access areas of up to 75 metres, is also fitted with an optional built-in heater so can be used in very low temperatures (down to -30°C). This means it can be used outside, for example in the wood or cement industry, in gravel pits or in docks.
