OPB365L51

Introduction

The OPB365L51 is a slot type, transistor output, photointerrupter device specially designed for applications which require high precision non-contact sensing. It is a mainstay among optical sensors in industry, providing highly reliable and robust non-contact sensing for a wide range of applications.

Application Field and Working Principle

The OPB365L51 is used in a wide variety of applications, including measuring proximity, rotation, position, and speed. It uses an infrared LED and a receiver to sense the presence of an object in its sensing range. The LED and receiver are housed in a separate package and connected to a single circuit board. When an object enters the sensing range, the infrared light emitted by the LED is blocked, causing a decrease in the current flow through the receiver. The receiver then sends a signal to the external circuit, activating a switch or triggering some other action.

Design and Features

The OPB365L51 is designed for efficient operation in harsh environments. It is constructed of a durable thermoplastic and features a wide viewing angle and high resolution. It is resistant to vibration and EMC interference, and has a wide operating range. The device is designed to work with either 3V or 5V power supplies, and is available with either an NPN or PNP output signal configuration. Additionally, the OPB365L51 features an integrated photodiode, allowing it to detect IR radiation from both internal and external sources.

Benefits

The main benefits of the OPB365L51 are its non-contact sensing, high accuracy, and wide operating range. Additionally, it is easy to install and requires minimal external components. The OPB365L51 is also extremely reliable, making it suitable for industrial applications.
