The ZA642 was discontinued on 30.09.2023.
In certain applications, the touchMATRIX® devices DX350 or IX350 can be used as a substitute.
The ZA642 dual-channel universal counter designed for limit frequencies up to 1 MHz features a 6-decade LED display as well as a scalable analogue output for selective operation with voltage or current. Thanks to its highly programmable operating modes (batch counting, forward / back counting, difference, event, cumulative count or length and position detection), the device is predestined even for the most demanding counting requirements on a wide range of machines and systems.
In contrast to the ZA640, this version has 2 additional pre-selection switches on the front, which can be used for the comfortable and direct presetting of limit values.
