Measuring wheel OKIII - 400M - metrologically verifiable CMI

Wheels are supplied with accuracy:
100 mm (OKIII-400x/1z - 1 tooth per turn)
10 mm (OKIII-400x - 10 teeth per turn)
2 mm (OKIII-400x/50z - 50 teeth per turn)
1 mm (OKIII-400x/100z - 100 teeth per turn)
- or upon request - to order

The number of impulses per 1 rotation of the wheel is 32, 64-8192, 40, 80, 100, 162, 200, 320, 400, 500, 800, 1000, 2000
Wheels with an accuracy of 100 - 2 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 2 mm (1 mm, on request - to order) are already equipped with a magneto-electric sensor and can therefore be connected to both NPN (sink) and PNP (source) circuits without the need for further changes.
< br> Measuring wheels OKIII-400, i.e. with a circumference of 400 mm, are produced not only with a basic coating of the wheel with white rubber. Type OC is available with a stainless steel wheel with diagonal radiating (transverse radiating can also be made on request).
The sealable wheel marked M can be used in the assembly as a fixed, metrologically verifiable gauge. The basic model without verification 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 designs can be supplied (see above).

The measuring wheel OKIII-400 with this circuit is produced in the following versions:
- OK III 400 - wheel surface coated with white rubber - basic version - offered as a separate product
- OK III 400 M - metrological (sealable), wheel surface coated with white rubber
- OK III 400 OC - stainless steel wheel with a diagonally grooved surface - offered as a separate product
- OK III 400 M OC - metrological gauge (sealable), stainless steel wheel with diagonally grooved surface
