Type 4/PLe

These single beam safety devices are operated in combination with the MSI-TRM monitoring device. Together with this, they form type 4 electro-sensitive protective equipment for applications up to PL e. Thanks to their compact dimensions and designs with cubic or cylindrical housings, they are easy to integrate. The operating range is up to 70 m. By alternating the use of red light and infrared light models, faults caused by mutual interference can be avoided.
