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.
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.
