Rotary potentiometer, magnetic type, complete separation, non-contact.
MRP-5026 Makome Research Institute
Magnetic type, complete separation, non-contact (up to 10 mm) rotation angle detection!! Rotary potentiometer.
This product was born from our company's linear encoder detection technology. It detects the magnetic fields of the N and S poles and outputs the rotational movement amount in analog form. By using a two-pole magnet, a detection distance (the gap between the sensor and the magnetic body) of 8mm ± 2mm is achieved. It allows for eccentricity within Φ1mm (±0.5mm). Due to the lack of mechanical connections, it is resistant to vibrations and shocks, making it suitable for use in rotating parts of robotic arms and construction machinery without coupling. Additionally, due to the absence of resistance, it can also be applied to tension control for films and paper. Please consult us regarding changes to the shape of the magnetic body. Sister product: Rotary encoder We also have the MRE-5049 with transistor AB phase output. *Linear sensor, linear rotary sensor We have evaluation samples available, so please feel free to contact us.
