Battery powered LCD electronic counter special
CH
Series
Data sheet
Our
CH Series electronic LCD counters have a small panel footprint
and are powered by a lithium battery. They
have a 7-digit LCD display, a push button reset, and accept a
wide range of inputs. Their reset function can be disabled if
desired.
These self-powered LCD counters are designed for applications
where no external power is available, as replacements for electromechanical
counters, event counting and part counting. Some typical applications
include: Amusement machines, dispensing machines, ticket machines,
copiers, printers, utility meters and portable equipment. |

Sensor wiring examples for the CH series counters
|
CH-7N with a magnetic sensor - no power required. Model CH-7N increments one count every time the magnet comes into the operating distance of the sensors.
|
|
CH-7P with a PNP output proximity sensor. The CH-7P increments one count every time a target actuates the sensors. |
