The encoder is used to convert linear displacements of key machine components into electrical signals containing information about the value and direction of the displacement.
The encoder is intended to use in particular heavy conditions. It is protected against products of technological processes and mechanical actions.
Encoder consists of metal based magnetic band MP, reading head and profile rail PS with protective band. The length of magnetic band could be up to 50 m (MP500 up to 20 m).
Encoder could be supplied with external zero signal actuator (magnet), which allows usage one of many reference marks made on magnetic band. Zero signal actuator is not necessary if the magnetic band with reference marks made according customer requirements (MP200Z) is used. The reading head has LED, which indicates the reference mark passage through head. In encoder PCMT the compressed air (P = 600 kPa) is blowed into case of head to clean the rail surface from small fragments.
Two versions of output signals are available:
• – PCMT-F – Square-wave signals, with integrated subdividing electronics for interpolation.
• – PCMT-AV – Sinusoidal signals, with amplitude approx. 1 Vpp, which require external subdividing electronics.
