## **Description**
## **Part selection key**
The Carlo Gavazzi PAM03 amplification module can operate alone, controlling 3 MOF... sensor sets. Up to 10 amplifiers can also be connected automatically in a master/slave setup via the built-in communication port sharing power and controlling up to 30 MOF... sensor sets. All connected MOF... sensors are multiplexed, eliminating crosstalk.
Due to their signal strength, the combination of MOF... sensor sets and PAM03 amplifiers are
suitable for environments with high amounts of dust or fog like automatic industrial doors, stone crushing conveyors, wood working machinery, car washes or other applications where a photoelectric sensor must work despite a build-up of dust and dirt or sense through fog, vapor or similar visibility hindrances.
The Carlo Gavazzi photoelectric PAM03 amplifiers are available in a plastic (PC/ABS) IP20 approved housing material.
