4. Handling notes

4.1 Toothed wheel
LENORD
another toothed wheel please note the following:
• Optimum measuring results will be achieved with involute tooth form
and modules 0.3 or 0.5.
• Mechanical inaccuracies concerning the tooth period, the tooth shape
and the concentricity have a negative effect on the measuring
accuracy.
• A mounted reference mark (see next section) must not exceed the
addendum circle of the toothed wheel.
• If the toothed wheel shows an eccentricity the probe must be
adjusted in such a way that the gap tolerance is maintained in case of
the smallest distance to the toothed wheel (see section 4.2).

Type code 244 Y ... indicates a customer-specific version. Deviations from
the type code above and/or the technical specifications are possible.
Mechanical impacts and the like onto the measuring surface of the MiniCoder can
permanently damage the probe!
Because of the very small gap between the probe's front end surface and the
target (toothed wheel) a build-up of metallic particles in this range may lead to the
destruction of the MiniCoder or to measuring inaccuracies. In case that this
situation may occur, please provide adequate cleaning mechanisms (e.g. a
collection magnet for ferromagnetic chips).
+ manufactures customised toothed wheels. If you use
BAUER
Do not use the toothed wheel for driving any components but only for measuring
purposes; the teeth must not wear out!
