PANTRONISG-A133Transistor output

ISG-A133

The ISG-A133 extends the configurable A123 platform by adding adjustable switching-on and switching-off delay from 0 to 10 seconds. It retains automatic transmit power adjustment, test input, selectable transmit level, selectable switching behavior, and transistor NPN / PNP output.

Key Features

Automatic transmit power adjustment for stable sensing in dirty environments.
Adjustable switching-on and switching-off delay from 0 to 10 seconds.
4-step basic transmit level selection.
Selectable light / dark switching and selectable transmit frequency.
NPN / PNP transistor switching output with separate PNP alarm output.
Test / reset input for system checks.

Best Fit Applications

Installations that need deliberate time delays to stabilize process transitions.
Harsh industrial machinery with contamination, spray, dust, or signal fluctuation.
Panels where transistor outputs and adjustable timing are preferred.
General-purpose long-range light barrier applications with configurable behavior.

This model was created from Pantron catalog pages 26-29 within the ISG-series automatic amplifier family. It shares the same through-beam range table and enclosure format as its paired companion model, ISG-A134.
