EGE Elektronik Sensor with Integrated Amplifier Productseries SN 450 GA-3M

Description

The EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450-GA-3M is the professional choice for automated facilities utilizing NPN-logic control architectures. By integrating the signal processing electronics directly into the sensor head, EGE has eliminated the need for external amplifiers or rack-mounted modules. The “GA” designation identifies its NPN switching output, while the “3M” suffix indicates a factory-fitted 3-meter cable, allowing for longer wire runs from the process line to the control box.

Features

Integrated Evaluation Amplifier: Built-in electronics process all signals internally, reducing control cabinet space and wiring complexity.
NPN Switching Output (GA): Optimized for direct connection to NPN-input PLCs and sinking-logic industrial controllers.
Extended 3-Meter Cable: Factory-sealed fixed cable provides extra reach for larger machinery or remote installation points.

Applications

Pump Dry-Run Protection: Instantly detects the loss of fluid to protect high-value pumps from cavitation and overheating.
Cooling System Monitoring: Verifying water flow in welding robots, induction furnaces, and power electronics.
Remote Installation: The 3-meter cable allows for mounting on large machines where standard 2-meter cables fall short.
