The SA642 was discontinued on 30.09.2023.
In certain applications, the touchMATRIX® devices DX350 or IX350 can be used as a substitute.
The variant SA642 corresponds in all functions as well as the design of the device type SA640. It is used as a universally programmable frequency or difference display with 2 incremental encoder inputs for recording two speeds, lead times, speed ratios or rotational speed differences.
The SA642 also has 2 front-side thumbwheel switches for fast and direct specification of limit values for the switching function of the transistor or relay outputs.
