ISG-A Series

Pantron’s ISG-A family is designed for applications that require reliable switching performance with automatically maintained sensitivity. The series continuously compensates for contamination, mounting drift, and other process disturbances, helping maintain dependable detection in harsh service conditions. Selected teach-in versions also support object differentiation based on transparency, making the range suitable for more challenging detection tasks.

Series Overview

The ISG-A lineup provides a broad set of single-channel amplifier options for OEM equipment, access systems, and contamination-heavy machine environments. Across the range, users can select relay or transistor output versions, add test-input capability where required, and step up to timer-equipped models for applications that benefit from switching delay. Higher-function variants add light/dark switching, dual transmit frequencies, and multi-level automatic setting to support more robust performance in variable operating conditions.

Functional Overview

Model Auto Levels Relay Output Transistor Output Alarm Output Switching Delay Test Input Teach Function

ISG-A114 2-level
ISG-A123 4-level NPN / PNP
ISG-A124 4-level
ISG-A133 4-level NPN / PNP
ISG-A134 4-level
ISG-A143 4-level NPN / PNP
ISG-A144 4-level

All ISG-A models provide two transmit frequencies and light/dark switching selection. 4-level automatic models adjust sensitivity across a wider operating range for more demanding environments.
