Photoelectric Proximity Switch WTR2-P521 without solenoid valve, dark switching

Sensor, logic, and valve (solenoid valve/engine actuation) product variants available in a single housing or as individual units.
Housing design adapted to suit roller conveyor modules
Precise background suppression with photoelectric proximity sensors with long, adjustable sensing range of 300 mm to 900 mm.
Integrated logic ensures controlled flow of goods on conveyor systems, e.g. single feed, block feed, single release, or block release
Electrical output for motor actuation or integrated solenoid valve
Modular structure (with or without solenoid valve or motor actuation, with or without logic)

Your benefits

All-in-one solution: sensor + logic + valve in one housing
Space-saving and protected mounting, integration below conveying level
Reliable detection of the transported products and containers without the addition of reflectors
The ideal standalone solution, saving on cabling, simplifying control, and permitting clearly structured, modular expansion of conveyor systems
Controlled flow of goods with starting/stopping within a conveyor belt - easy and reliable
Very high availability of the conveyor systems thanks to controlled flow of materials - and therefore reduced costs
Flexible process engineering through modularity
