The EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450-A4-GRS is the authoritative choice for modern automated facilities requiring rapid installation and flexible switching capabilities.
The EGE Elektronik Sensors with Integrated Amplifier Productseries SN 450-A4-GRS is the authoritative choice for modern automated facilities requiring rapid installation and flexible switching capabilities. The “GRS” designation identifies the specific hardware configuration: a potential-free relay stage (GR) paired with a standardized M12 connector (S). This setup allows for quick-disconnect maintenance, significantly reducing downtime compared to fixed-cable models.
EGE-Elektronik Spezial-Sensoren GmbH has been developing and manufacturing special purpose sensors for automation applications since 1976. The company serves leading international producers from a wide range of industries. Its product portfolio includes flow controllers, infrared, opto and ultrasonic sensors, capacitive proximity switches, light barriers and inductive proximity switches. EGE also provides sensors for highly sensitive applications, e. g. hazardous areas. The development department`s highly qualified staff cooperates closely with all customers, ensuring continuous product updates and enhancement.
EGE has been a pioneer in the field of flow controller and an innovator and decisive participant in the development of today's globally utilized thermal flow controllers. The in-house EMC and test laboratories ensure that all inspections and tests required for permits and conformity certificates are carried out quickly and reliably. Product quality is guaranteed with a continuously monitored quality management system in accordance with EN ISO 9001:2000.
