EGE Elektronik Sensor Air Flow Sensors Productseries LNZ 450 GR-S

Description

The EGE Elektronik LNZ 450 GR-S is the authoritative choice for industrial facilities that require the robustness of 230V AC power combined with the modern convenience of modular connectivity. The “GR” designation indicates a semiconductor switching output designed for AC control loops, while the “-S” suffix signifies an M12 plug-in interface. This modularity is a key advantage for high-uptime environments, as it allows for immediate sensor replacement without the need to disconnect hard-wired cables.
