OPB990T51Z

Optical sensors are widely used in many different industries and applications due to their robustness and reliability. Photointerrupters are a type of optical sensor that use a beam of light to detect changes in the environment. The OPB990T51Z is a slot type logic output photointerrupter available from Optek Technology. This article will explore the application field and working principle of the OPB990T51Z.

The OPB990T51Z is a popular sensor for detecting the position and motion of an object or person. It is designed to detect a slot or gap in a surface or material, and can be used to detect the presence of an object, the movement of an object, or the absence of an object. The OPB990T51Z is commonly used in industrial applications for material level detection, absence detection, and speed/distance measurements.

The OPB990T51Z photointerrupter uses an infrared LED and phototransistor pair to detect the positioning of an object or surface. The phototransistor is connected to a logic output, which provides a digital output when the sensor is triggered. The OPB990T51Z is designed to operate at an operating voltage of 5V and can be triggered by a surface or object up to 10mm away from the sensor. This sensor has a strobe time of 100µs and a response time of 10ms.

The OPB990T51Z is designed to operate in challenging environmental conditions. The sensor has an operating temperature range of -25°C to +85°C and an insulation resistance of 100MΩ. The sensor also has a durable construction that is designed to withstand shock and vibration. The OPB990T51Z can be mounted directly onto the target surface, and is available in a variety of different package styles.

The OPB990T51Z is an ideal solution for applications requiring accurate and reliable position sensing. The logic output provides a reliable solution for detecting the presence or absence of an object or surface, and the durable construction allows the sensor to be used in challenging environments. The OPB990T51Z is an excellent choice for detecting the presence of objects or surfaces in industrial applications.
