The OPB420BZ optical sensos is a crystal-controlled slot type photointerrupter with a transistor output design. It is designed to provide accurate and reliable high-frequency switching performance in a wide range of environmental conditions. It can easily detect the passage of small objects, such as small coins, and has a very high sensitivity range to detect even very faint objects.

The OPB420BZ optical sensors are manufactured to meet the stringent precision requirements of the most demanding applications. It is suitable for replacing mechanical sensors in harsh environments, including humidity, temperature and dust. The design of this photointerrupter ensures maximum reliability and performance in a variety of applications.

The OPB420BZ optical sensos consists of an infrared emitting diode and an NPN silicon phototransistor mounted in an epoxy-snap-to-hold package. The phototransistor output changes with the variation of incident infrared light level, which is affected by the passage of the object through the slot pattern. The NPN type output is low when the slot pattern is not blocked, and high when the slot is blocked. This ensures a very fast response time of up to 10kHz. The device is very small, measuring 20 x 11.8 x 9.2mm

The optical sensos can work in a wide range of environmental conditions, such as temperature, humidity and dust. It has high reliability and long service lifetimes. The OPB420BZ features a wide operating voltage range, a low power consumption and a very low trigger voltage, making it very efficient for many applications. Its wide operating temperature range also makes it suitable for tough industrial settings.

The OPB420BZ optical sensos is ideal for applications where quick, accurate and reliable switching performance is needed. It is suitable for use in optical equipment, pick-and-place machines, sorting systems, door, lock, and window control systems, optical sensing systems, security systems, and other applications where low power consumption, small size, and reliability are important factors.

In summary, the OPB420BZ Optical Sensors is a crystal-controlled slot type photointerrupter with transistor output design. It offers very fast response time, a low trigger voltage, low power consumption, a wide operating voltage range, and a long service lifetime. It is very small, lightweight, and reliable, while providing accurate and reliable high-frequency switching performance in a wide range of environmental conditions. It is ideal for use in a variety of optical sensing, security, and industrial applications.
