Rotary encoder, magnetic type, completely isolated, non-contact.
MRE-5049 Makome Research Institute
Magnetic type, complete separation, non-contact (up to 10mm) rotation angle detection!! Rotary encoder
This product was born from our company's linear encoder detection technology. It detects the magnetic field of the N and S poles and outputs the rotational movement as pulses. By using a two-pole magnet, a detection distance (the gap between the sensor and the magnetic body) of 8mm ± 2mm is achieved. Eccentricity is allowed up to Φ1mm (±0.5mm). Due to the absence of mechanical connections, it is resistant to vibration and shock, making it suitable for use in rotating parts of robotic arms and construction machinery without coupling. Additionally, due to the lack of resistance, it can also be applied to tension control for films and paper. Please consult us regarding the shape of the magnetic body and the number of pulses per rotation. Sister product: Rotary Potentiometer We also have the MRP-5026 with a voltage output of 1-5V and a current output of 4-20mA. *Linear sensor, linear rotary sensor We also have evaluation samples available, so please feel free to contact us.
