MAGNETIC ACTUATION

The counter is actuated by a magnetic field. With suitable magnets it is possible

to achieve actuating distances of up to 50 mm. The direction of approach of the

actuating magnet is not critical. When choosing a counter, it is important to

observe the correct polarity of the actuator (see Figure).

ACTUATING MAGNETS

We supply suitable magnets for actua-

ting this counter.

For mounting the magnet via its center

hole only screws made of non-magnetic

material may be used.
