Optical Sensors, Photointerrupters, and Slot Types are common applications in a variety of automation, experimentation, and industrial applications. The OPB841W55Z is an optical outputs transistor photointerrupter. This device provides an electrical output signal when an object passes through the slot. The OPB841W55Z is a standard type of photo interrupter and has a low package height and low cost. It is used in positioning, presence detection, presence sensing, monitoring, and infrared control applications.

The OPB841W55Z consists of an LED emitting infrared light and an integrated phototransistor receiving and detecting the emitted light. An opaque object passing through the slot interrupts the emitted infrared light, which is then detected by the phototransistor and converted to an electrical output signal. The presence of a light-blocking object will activate the electrical output signal normally; conversely, the absence of a light-blocking object will deactivate the electrical output signal.

The OPB841W55Z has a high level of accuracy and sensitivity, and it is designed to detect objects between 7mm and 15mm in size. The device is offered in two sensing methods – reflective and transmissive. The reflective method requires a reflective body, such as a label, to be mounted on the target object, which is then detected by the LED and receiver. In the transmissive mode, the target is detected directly by the transmitter and receiver, and no additional reflectors or transducers are needed for detection.

The OPB841W55Z has a high-speed response time of up to 1ms. It can detect a target through a slot with dimensions as small as 0.6mm in width and 0.5mm in height. It has a wide operating temperature range of -20°C to +85°C and is available in a range of mountable packages, including surface-mount and through-hole packages.

The OPB841W55Z is an efficient, durable, and reliable optical photointerrupter suitable for a variety of applications. It has a fast response time and high accuracy, and its compact size is ideal for tight spaces. The device can detect a variety of targets, including paper, labels, objects, and liquids. It is suitable for detection in a variety of automated systems and devices, including conveyors, robots, and positioning systems.

In conclusion, the OPB841W55Z is a reliable and efficient optical photointerrupter suitable for many applications. It can detect a variety of targets and has a fast response time. Its features make it ideal for a wide range of applications from automation, experimentation, and industrial applications to positioning, presence detection, and infrared control.
