ISG-N127 Infrared Photoelectric Amplifier

Manufacturer: Pantron Instruments, GmbH
Category: Infrared Photoelectric Amplifiers

Pantron amplifiers operate with modulated infrared light which provides high immunity to ambient light. The electronic circuit is designed to detect only those signals with the correct frequency and phase relation. This almost completely excludes interference from other barriers.
