Z20 provides a rugged cost effective quality panel mounting instrument. This small, compact unit has an 8 mm high, red LED display and provides a convenient, precise and easily readable indication of position. Using the dust-tight keypad (and external signal if required) the display can be reset or preset a datum value. The standard unit evaluates conventional, incremental square waves (Channels A,B and Z) of optical rotary encoders and also the magnetic ELGO measuring systems LMIX, EMIX, MIX, PMIX and FMIX (if ordered with measuring system index M or N).

The special version Z20-005 (see image) is already equipped with a connector to the magnetic sensor ELGO-MS20.60. The translator circuit is already integrated in the indicator unit. For correct measuring, a magnetic tape with 5 mm pole distance is necessary (e.g. ELGO MB20.50). The gap between sensor and tape must be 0.1... 0.8 mm.
