Pair of outdoor photocells Positionable 30°,for connection via BlueBus Nice EPMOB Safe: D type device according to specification EN12453 which allows to pick-up obstacles on the optical axis between transmitter (TX) and receiver (RX). Using the fototest function it is possible to achieve class 2 safety fault according to specification EN 954-1. Cutting-edge technologies: antiglare circuit which eliminates possible sunlight interference. Practical: Positionable 30° angle (Mod. EPMOB). The positionable versions allow for the compensation of centering gaps up to 30°. The models EPM, EPMO, EPMA and EPMAO provide for 2 range levels. Resistant and vandal-proof: ABS body resistant to weather conditions. Nice BlueBUS technology: all models are available with the BlueBUS system, which allows an easy connection to the control unit of all devices with only two wires, by simply connecting them in parallel and selecting the jumpers for addressing according to the needed function. The system acquires automatically the devices connected to the BlueBus network. Automatic synchronization between multiple photocell pairs in order to avoid other possible interferences between the devices. IB interface: allows the connection of photocells with Nice BlueBUS technology to control units having terminals for traditional contacts.
