Length measuring wheel OKIII - 200
The measuring wheel OK - III is used for measuring the lengths of flat or strip materials. The circumference of this wheel is 200 mm and it is always coated with white rubber. It works in cooperation not only with the LUCA unit, LUCA 2 and LUCA T.

Wheels are supplied with accuracy:
100 mm (OKIII-200x/1z - 1 tooth per turn)
10 mm (OKIII-200x - 10 teeth per turn)
1 mm (OKIII-200x/50z - 50 teeth per turn)
- or as desired - to order
Custom number of pulses per 1 turn of the wheel are 32, 64-8192, 40, 80, 100, 162, 200, 320, 400, 500, 800, 1000, 2000<
Wheels with an accuracy of 100 - 1 mm are made with an optoelectric design of the sensor and their output is therefore NPN (sink). In the event that you need to connect the NPN wheel to a counter other than LUCA (NPN), e.g. to a regular PLC (PNP), you will need to use resistors for each of the channels (Pull up connection).
Wheels with a higher accuracy than 1 mm (0.5 mm, on request - to order) are already equipped with a magneto-electric sensor and can therefore be connected to NPN (sink) and PNP (source) circuits without the need for further changes.
Measuring wheels OK - III, i.e. with a circumference of 200 mm, are produced only with a white rubber covering of the wheel.
A sealable wheel marked M, which can be used in the assembly as a fixed, metrologically verifiable measuring device, is offered as a separate product.
The wheel is housed in a pair of ball bearings. In the standard version, the axis of the wheel is attached to a hinged metal arm 160 mm long. An electronic evaluation circuit is built into the measuring wheel, which generates two phase-shifted sequences of pulses when the wheel rotates. From them, the measured distance and direction of rotation of the wheel can be evaluated. In the standard version, one pulse edge corresponds to 10 mm (wheel without resolution marking). Different resolutions can be supplied (see above).
