PANTRONISG-A113Transistor output

ISG-A113

The ISG-A113 is a single-channel automatic infrared amplifier for harsh industrial environments. It uses automatic transmit-power adjustment, a 2-step basic transmit level, light switching behavior, and an NPN / PNP transistor switching output. An additional PNP alarm output is included for status monitoring.

Key Features

Detection range up to 50 m in through-beam applications with compatible transmitter / receiver pairs.
Automatic transmit power adjustment for stable operation in contamination-heavy environments.
Basic transmit level selectable between low1 and low2.
Light switching behavior with 25 ms reaction time.
Switching output uses a transistor stage with NPN / PNP option.
Separate PNP alarm output for system status indication.

Best Fit Applications

Industrial gates, doors, and machine guarding where long-range optical sensing is needed.
Timber, paper, food, and wash environments with dirt, fog, spray, or dust.
Panels that require transistor-level output rather than relay switching.
Retrofits where DIN-plug connection and compact enclosure depth are preferred.
