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

Description

The EGE Elektronik LN 450 GSP-K is the authoritative choice for machine builders and engineers who require a “set-and-forget” airflow monitoring solution. The “GSP” designation signifies a standard 24V DC operating voltage with a PNP transistor output, making it plug-and-play compatible with almost all industrial PLC systems. The “-K” suffix indicates the integrated fixed cable, which provides a high-integrity, tamper-proof connection that is ideal for permanent mounting where a plug-in connector might be unnecessary or prone to unauthorized removal.

Features

PNP Switching Output (GSP): Designed for direct, high-speed communication with 24V DC industrial controllers.
Integrated Fixed Cable (-K): 2-meter factory-sealed cable ensures a robust, hermetic connection with an IP 67 rating.
Space-Saving Design: A compact form factor allows for installation in tight spaces where larger LNZ models cannot fit.

Applications

Control Cabinet Monitoring: Protecting critical electronics by verifying the operation of 24V DC cooling fans.
Heater Safety Interlocks: Preventing heating elements from activating unless sufficient airflow is detected.
Small Exhaust Ducts: Monitoring airflow in laboratory fume hoods or soldering stations.
