Even though the sensor is extremely small, the sensing distance is not compromised. Up to a 2m detection distance is possible with the thrubeam type, 200mm with the retro-reflective type, and 160mm for the diffuse reflective type. A visible red beam spot allows for easy confirmation of alignment. Also, the LED used in the EX-20 series provides a high-power, narrow beam that can produce a spot as small as 1mm in diameter. This is great for the detection of small objects such as chip components or wires. The mounting options available include a front sensing type as well as a side sensing type. Each type has two, metal reinforced M3 mounting holes for stable sensor placement. All types are available as either Light ON or Dark ON and PNP or NPN. Output Output Emitting Max. Range Max.

Further, the sensing range is the possible setting range for the reflector. The sensor Setting range of the reflector can detect an object less than 30 mm 1.181 inaway. However, if the reflector is set 100 mm 3.937 in or less away, the sensing object should be opaque. Notes: 4) In case of using this product at a sensing range of 50 mm 1.969 in or less, take care that the sensitivity adjustment range becomes extremely narrow. Sensor Reflector Reflector
