Multiplex Photoelectric Detection for Industrial Automation
A photoelectric amplifier processes signals from separate emitter and receiver sensor heads and converts the detected beam condition into an electrical switching signal for industrial control equipment. Through-beam sensing provides long detection distances and dependable object detection, while locating the amplifier separately allows adjustments and diagnostics to remain accessible within the control system.
The Carlo Gavazzi S142CRXA230 adds a microprocessor-controlled multiplex system that allows master/slave operation with high immunity to interference from neighbouring optical channels. Automatic or manual emitter regulation, self-diagnostics, alignment assistance and an SPDT relay output make it particularly suitable for installations requiring multiple reliable through-beam detection points.
Typical Applications
- Long-range through-beam object detection.
- Multiple adjacent photoelectric sensing channels.
- Industrial conveyor and material handling systems.
- Packaging and production machinery.
- Warehouse and logistics automation.
- Automated manufacturing and assembly equipment.
- Presence and position monitoring.
- Industrial machine-control and automation systems.
