Schreiber SM48 Series Inductive Slot Sensor | 20mm Accuracy
- Manufacturer: Schreiber Messtechnik
- Category: Displacement, Amplified LVDTs, SENSORS, LVDT Sensors
He inductive slot sensor The Schreiber SM48 series is a specialized transducer designed for precise positioning by detecting the movement of a metal fin. With a 22 mm slot spacing and a 20 mm measuring stroke, this device uses a dual-coil facing system that detects changes in magnetic coupling without physical contact. It is the preferred technical solution for the positioning of machine tables and transport carts where absolute reliability is required under conditions of intense vibration.
This inductive transducer It incorporates all the conditioning electronics in its robust black anodized aluminum housing, allowing for direct integration without the need for external amplifiers. Thanks to its protection IP66 and its ability to withstand shocks of up to 20g SRS, the SM48 allows Read the position of metal fins with PLC with an accuracy of 0.5%, maintaining a minimum thermal drift (< 0.01%/ºC). Consult with our technical department for the ideal fin design for your application.
