PANTRONISG-N27 series11-pole DIN plug

ISG-N27

The ISG-N27 adds alarm signaling to the configurable ISG platform. It provides adjustable sensitivity, selectable light/dark mode, four frequencies, relay and transistor outputs, plus an alarm output for power-limit monitoring in tough sensing applications.

Datasheet PDF Operating Guide PDF

Up to 70 m range Alarm output 3.5 / 3.8 / 4.0 / 4.4 kHz Light / dark selectable Relay + NPN/PNP IP40 housing

Key Features

Sensitivity adjustable with front potentiometer.
Selectable basic transmit level and light / dark switching.
Four selectable transmit frequencies.
Relay change-over and NPN / PNP transistor switching outputs.
Alarm output for power-limit or fault indication.
Designed for long-range use with Pantron through-beam pairs.

Best Fit Applications

Critical installations that need separate alarm indication.
Dusty or wet applications where optical reserve should be monitored.
Machine interfaces that need both relay and transistor outputs.
Installations where different transmit frequencies help prevent cross-talk.
