EGE Elektronik Sensor Air Flow Sensors Productseries LNZ 450 GSP-K

Description

The EGE Elektronik LNZ 450 GSP-K is the authoritative choice for permanent industrial installations where a high degree of environmental protection is required. The “GSP” designation indicates a 24V DC operating voltage with a PNP transistor output, allowing for direct integration into PLC control loops. The “-K” suffix signifies a factory-connected fixed cable, which offers a superior hermetic seal compared to plug-in versions—ideal for environments with high humidity or where tampering must be prevented.
