EGE Elektronik Sensor Amplifiers Productseries SKM 420 GA

Description

The EGE Elektronik SKM 420 GA is the authoritative choice for high-speed industrial monitoring. By separating the rugged sensor probe from the evaluation logic, the SKM 420 GA allows you to mount the sensing head in extreme process conditions while keeping the sensitive calibration electronics safe and accessible within a control cabinet. The “GA” designation identifies this unit’s focus on electronic switching. Unlike relay-based amplifiers, the GA model utilizes a transistor output, providing a wear-free interface that can handle millions of switching cycles. This makes it the ideal partner for high-speed PLC inputs and applications where mechanical contact failure could lead to costly downtime.
