EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450-A4-GSP-S is the authoritative choice for facilities requiring rapid installation and high-reliability flow sensing.
EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450-A4-GSP-S is the authoritative choice for facilities requiring rapid installation and high-reliability flow sensing. The “GSP” designation indicates the PNP switching output (sourcing logic), which is the standard for most modern European PLCs. The “S” suffix highlights the inclusion of a standardized M12 connector, allowing for quick-disconnect maintenance and tool-free sensor replacement.
