Linear Displacement Sensor (Sleeve Sensor): Makome Laboratory
Sleeve Sensor ET Series
Outputs relative position with DC voltage, robust and highly durable absolute type, custom shape for detecting suspension stroke in racing bikes.
The detection body consists of two components: the "sleeve" and the "probe" of the detection part. A high-frequency magnetic field is generated on the probe side, creating electromagnetic induction coupling between the sleeve and the probe. When the sleeve displaces relative to the probe, changes occur in the electromagnetic induction coupling, which are converted into voltage and output (the relative position of the sleeve and probe is output as a displacement amount in the range of 1-5V). Since the sleeve and probe have a completely non-contact structure, there is no deformation or failure due to friction. 【Main Features】 ■ Two models available: the integrated detector 'ET-850' and the separated type 'ET-851A' ■ The probe is made of stainless steel, ensuring both robustness and durability ■ The protective structure complies with IP-67, providing high dust and water resistance ■ Power supply voltage DC10-30V *For more details, please download the catalog or contact us.
Inquire About This Product
basic information
The "sleeve" (metal tube) and "probe" (rod-shaped detection coil) are non-contact, which greatly reduces the impact of dirt and vibrations on measurements. Additionally, there is no deformation or failure due to wear, and installation can be easily performed. ○ ET-850 is a standard sensor that integrates a probe with a built-in coil and a detector with a circuit. ○ ET-851A has a probe with a built-in coil that is exposed to heat and pressure, but the detector is separate, so the circuit is not affected by this heat and pressure. *For more details, please download the catalog or contact us.
