Optical Sensors - Photointerrupters - Slot Type - Transistor Output

OPB870N11 is a slot type transistor output optical sensor that is capable of sensing objects through an on/off output signal. The device provides a fast and accurate detection of varied objects, which moves at speeds up to 500 metres per minute. Built with an extremely small optical slot, it is suitable for detecting extremely small objects. This sensor is best fitted for applications that require extremely fast response time or for applications with high speed objects.

Working Principle

The OPB870N11 is designed to operate along a simple principle. When light passes through the slot, a photocoupler and a phototransistor are triggered, resulting in a transistor output signal. If the slot is closed, the transistor output is switched off, and when the slot is open, the transistor output is switched on. This high speed switching signal is suitable for controlling robots or other type of automated machinery.

Features

The OPB870N11 provides an extremely fast switching speed, with a maximum response frequency of 30kHz. It has an IR LED output signal that emits an infrared signal of 700nm. The wide operational temperature range, from -40 C to +85 C, makes it suitable for a wide range of application conditions. The miniature size of the device allows it to be conveniently mounted in tight spaces or into small machines. The device also features a high immunity against EMI and ESD for reliable operation.

Applications and Benefits

The OPB870N11 can be used in a wide range of motion control and robotic applications. It is commonly used for accurately measuring distance and for detecting objects passing through a slot. This type of sensor is often used in automated equipment such as robots and machine tools. It is ideal for applications that require a high speed response time, such as process control, robotic welding and pick-and-place operations. Additionally, the sensor is used in medical technologies, automotive applications and semiconductor production.

The OPB870N11 is a reliable and high speed optical sensor that is suitable for a wide range of applications. Its small size, fast response time and high accuracy makes it an ideal solution for process automation, robotic welding, and distance measuring.
