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.

Utilizing our original technology of saturable coils, we offer a fundamentally simple magnetic detection element technology that provides high precision and long-term stability even under adverse conditions. We have received strong support from a wide range of industries, including unmanned transport carts, industrial equipment, labor-saving machines, material handling, machine tools, injection molding machines, civil engineering and construction robots, food machinery, industrial machinery, nuclear facilities, and ships. We also excel in sensors for motorsports such as F1 and Moto GP, tilt meters for construction machinery, and magnetic sensors used for ultra-high precision measurements in scientific fields. Some of our products are also used in applications like multi-story parking and golf cart guidance sensors. All of our products are developed and manufactured 100% in Japan, with over 80% of our product lineup being custom-made based on individual customer requests. We have many custom options available, including waterproof, explosion-proof, heat-resistant, water-resistant, and radiation-resistant specifications. If you have any issues related to sensing or measurement, please feel free to consult us. IoT Platform: Our sales and technical staff are fully committed to addressing everything from minor customizations of existing products to proposing new detection principles. You can also rely on us for assistance with improvements. Our standard products come with a reassuring 3-year warranty. Location: Ina, Nagano Prefecture. Published on Ipros Monozukuri.
