For contactless object detection in your industrial equipment, go for this photoelectric sensor from OMRON. Its retroreflective design means it emits a beam to a reflector and, if the beam is broken, the unit notifies a controller. This makes it an essential part of an automated system. Thanks to the sensor's relay output function, you can use it to switch electrical loads powering motors, lights and alarms. ABS housing gives it resistance to impact and wear. As it consumes just 2W of power during operation, this is an energy-efficient workmate.

• Comes with a mounting bracket for quick and easy assembly
• Lightweight at 160g so it puts minimal strain on your equipment
• Withstands a wide operating temperature range of -25°C to +55°C
• Supply Voltage 12 to 240 Vdc or 24 to 240 Vac
• IP66 rating indicates it's dustproof and resistant to high-pressure water jets

• Military equipment
• Assembly lines
• Storage facilities and warehouses

The unit has a sensing range of 4m, so it's ideal for use in large-scale setups.

This photoelectric sensor is a reliable option, thanks to its MSR (mirror surface rejection) function. This uses polarised light to reduce incorrect detection and keep your system running smoothly.
