Sleeve sensor

The "Sleeve Sensor" from Makome Research Institute consists of a metal tube sleeve of the object being detected and a probe that contains a position detection coil. It is an absolute type displacement measurement device that outputs the relative position as a direct current voltage. Since the "sleeve" (metal tube) and the "probe" (rod-shaped detection coil) are non-contact, the influence of dirt and vibration on the measurement is greatly reduced.

Non-contact linear displacement sensor MP-620 Absolute output

Non-contact linear displacement sensor that is resistant to vibrations and shock waves, ideal for position detection in linear devices such as air cylinders!

"MP-620 Series" Linear Displacement Sensor Utilizing multiple uniquely developed detection elements called "saturable coils," it detects the relative position to the detection body (magnet) non-contactly and provides linear output (voltage/current). Since each detection element captures the positional changes of the detection body (magnet), disturbances in output due to vibration or shock are almost nonexistent. The sensor part and the detection body are completely separated (8mm ± 2mm), preventing the generation of wear particles from contact. It is also suitable for absolute position detection of magnets embedded in oil pneumatic cylinders, etc. (Absolute). Ideal for measuring displacement in robotic arms and similar applications. 【Main Features】 ■ Power supply voltage DC +24V ■ Output MP-620 (voltage output 1-5V) MP-621 (current output 4-20mA) ■ Effective length 100mm to 800mm * Please consult for lengths over 800mm (maximum support up to 1600mm) ■ Repetition accuracy within 0.1mm ■ Capable of detecting various magnets compared to our conventional linear displacement sensors * Adjustments may be necessary. ■ Compared to our sleeve sensors, it has very little dead space and is compact. * There is also a small type MP-4731 with a 15mm stroke.

Linear displacement sensor (sleeve sensor) completely non-contact

Outputs relative position with DC voltage, a robust and highly durable absolute type, currently active in 2-wheel motorcycle racing! (Custom order available)

The detection body consists of two components: a "sleeve" and a "probe" for 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, and this change is converted into voltage output (the relative position of the sleeve and probe is output as a displacement amount in a voltage range of 1-5V). Since the sleeve and probe have a completely non-contact structure, there is no deformation or failure due to friction. We also accept various customizations such as mounting brackets and connectors. Please feel free to consult us. 【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 waterproof performance ■ Power supply voltage: DC 10-30V *For more details, please download the catalog or contact us.

Linear Non-contact Displacement Sensor ET Series: Makome Laboratory

Outputs relative position with DC voltage, featuring a robust, non-contact, and highly durable absolute type. Customizable and currently active in top-tier motorcycle racing!!

The detection body consists of two components: a "sleeve" and a "probe" at the detection part. 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, which are converted into voltage output (the relative position of the sleeve and probe is output as a displacement amount in a voltage 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: integrated detector 'ET-850' and 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 mounting, shape, etc. An image of a differential transformer (LVDT) reversed. *For more details, please download the catalog or contact us.
