Optical Sensors are widely used in many fields including automation, robotics, industrial machinery, medical device and consumer electronics. Among these, Photointerrupters with their logic output are preferred type for sensing the objects close to the slot gap of the sensor. OPB461L11 is an example of this type of sensors.

The OPB461L11 from Omron is an optical slot-type, logic output photointerrupter. It is designed for easy object detection in a wide range of applications from industrial to consumer products. The sensor has a very low profile and is suitable for applications requiring low space. It is also suitable for reflow soldering, making it ideal for use in automated assembly lines. The sensor has a very sensitive and reliable operation even with micro distance sensing.

The OPB461L11 utilizes an LED and a high sensitivity phototransistor to detect the object through a slot gap. The logic output of the sensor (low: ON, high: OFF) allows it to be integrated into variety of controllers either directly or by using a level shifting circuit. The incident angle of the light emitted by the LED and the reflected light reaching the phototransistor are widely adjustable by using respective lens. That way, the sensor can be adjusted to detect object in various shape, size and color.

The optimum detection distance of the OPB461L11 is 0.6 mm. It is a PBT (polybutylene terephtalate) package type device capable of withstanding 100 C maximum junction temperature, 500 V maximum surge voltage and 400 V ESD (electrostatic discharge) resistance. The operating temperature range of the OPB461L11 is 0 - 65 C.

Thanks to its adjustable slot gap, unique light source, and highly sensitive phototransistor, the OPB461L11 is a reliable and highly accurate sensor that is suitable for applications that require precise object recognition. Its small size and low profile makes it suitable for detecting small objects in limited spaces or embedded applications. It can be used in many applications such as conveyors, automated assembly lines, counting machines, and for sensing presence of an object.

The OPB461L11 is an optical sensor designed to detect the objects across its slot gap with its very sensitive and reliable output. Its adjustable slot gap and lens allows the sensor to detect different shapes, sizes and color. Its low profile and PBT package makes it ideal for applications requiring small form factor and embedded solutions. It is also suitable for use in conveyors, automated assembly lines, counting machines, and for sensing presence of an object.
