101 - 309 Totalising Revolution or Stroke Counter

Hengstler 101 - 309 small counters provide accurate mechanical recording for various revolution or stroke counting applications where continuous automated processes require a totalising readout.

Revolution counters are suited for continuous rotary movement and function bi-directionally. Stroke counters are for reciprocating motion within a limited degree of rotation; an internal spring returns the shaft to a start position, for example, on hand punch presses, photocopiers, or vending machines. Stroke counters count in one direction only.

Revolution and stroke counters are available with a non-resettable 4 or 5-digit display with a right or left rotary shaft. There are two types of shaft rotation, either BZ or BW.

• BZ shaft rotation, viewing the front display, the top of the rotary shaft is coming towards the observer.
• BW shaft rotation, viewing the front display, the top of the rotary shaft is going away from the observer.

Transmission ratios are 1:1 or 1:10, depending upon the version selected. Choose from a surface or flush-mounted counter or without housing.

Strike levers for the stroke counters are purchased separately.
