EX-20 Series Photoelectric Sensors
Ultra-compact Photoelectric Sensor
The EX-20 series reaches the pinnacle of sensor miniaturization. By fabricating the photodiode and the A/D conversion circuit on the same chip, SUNX has achieved one of the smallest built-in amplifier sensors in the world. With integrated sensitivity adjustment, the EX-20 series is great for use as an all-purpose sensor. 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.
