Product description: Potentiometric Linear Transducer SPR18

The displacement sensors of series SPR18 are used in industrial applications, which require a compact linear transducer with spring-suspended probe tip, long lifespan, high accuracy, rear and front guided push rod with measuring length from 25 to 100 mm.

The compact and robust linear potentiometers of the series SPR18 are designed for industrial applications. The housing profile made of anodized aluminium corresponds to the usual industrial dimension with 18x18 mm. The transducer has a stainless steel ball in the probe tip, for example for scanning profiles or for monitoring distances. In the displacement sensor series SPR18, the mechanical detection of linear movement is done by a rear and front guided push rod. The potentiometric distance measurement is carried out with a high-resolution conductive plastic resistive element. The compact displacement encoder has a very long lifetime and high accuracy due to its good linearity. Since the potentiometric measuring principle delivers absolute values and requires no electronic conversion, the position feedback signal is true power on without delay, temperature stable and robust against EMC influences. Customization on the cable (length, finishing with plug) or on the push rod (length, thread, flat ...) are available on request. The SPR18 is available with both plug and cable connection.
