MP Scale Rotary Encoders and Linear Scales
MP SCALE is a non-physical contact, ultra-precision position detector used for detecting linear or angular position utilizing the inductive coupling principle. The manufacture and sale of MP Scale was started with the technical cooperation of INDUCTOSYN Co. in U.S. since 1970.
MP Scale detects the amount of movement of a machine and outputs an analog signal. This signal is converted into a digital signal by an A/D converter and fed back to the NC system. Thus the machine can be controlled accurately by the fully closed-loop NC system based on the position feedback data from MP SCALE.
The control method which detects the last position (or angle) of the machine with the use of MP Scale detectors, and return detected data to NC equipment in order to move the machine to the target position (or angle).
These products are commonly called INDUCTOSYN scales and INDUCTOSYN rotary encoders.
MP Scale provides machines with stable and highly accurate position detection!
・It is necessary to prevent the intrusion of dust with air purge (compressed air).
・Maintenance is required against deterioration of bearings and springs, and wear of lip seals
⇒ Scale and machine have the same thermal expansion ≒ 11.0✕10-6K(m)
