Interfacing with the LS8000-3

Connecting Material Present Switches

This section shows how to connect a commonly used Material Present detector.

Single Switch Configuration

The D10 is a make/break optical switch. When connecting one optical switch, it should be aligned with the LS8000-3's measurement spot. This configuration can be used in order to more precisely detect the edge of the material. The fiber optic elements are much smaller than the LS8000-3 spot size, so repeatability is improved by more consistent edge detection.

The switch can be configured for either Light Operate or Dark Operate. When in Light Operate mode, the switch will output a voltage high when there is not an object blocking the beam, and when in Dark Operate mode, the switch will output a voltage high when there is an object blocking the beam. Also, the switch should be configured for Super High Speed (SHS) mode in order to minimize latency.
