Linear Non-contact Displacement Sensor ET Series: Makome Laboratory
Sleeve Sensor ET Series
Outputs relative position with DC voltage, robust and non-contact, boasting high durability, absolute type, custom-made, actively used in motorcycle racing!!
The detection system consists of two components: the "sleeve" of the detected object and the "probe" of the detection unit. A high-frequency magnetic field is generated on the probe side, creating electromagnetic induction coupling with the sleeve. When the sleeve displaces relative to the probe, changes occur in the electromagnetic induction coupling, and this change is converted into voltage for 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: DC 10-30V Custom options available for installation and shape, etc. *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 significantly 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 since the detector is separate, the circuit is not affected by this heat and pressure. *For more details, please download the catalog or contact us.
