Introduction to the Photosensor Blog! 'Photosensor Blog'

Introduction to the Photosensor Blog! 'Photosensor Blog'

Starting with the basic structure and types, we provide a wealth of content including alternative examples from other sensors, application cases, and customization examples!

★The launch of the 'Photosensor Blog' that answers everyone's "want to know"★ You can view it from the link below! Photosensors are quietly active behind the scenes around you. Most people have probably never even seen one. And that's understandable, as photosensors are very shy... They are working hard in the shadows, making significant contributions. In the 'Photosensor Blog' by Shin-Etsu Electronics, we focus on these unsung heroes, the photosensors, and deliver information that answers your "want to know"! 【A glimpse of the blog】 ■ Beginner's section (basic structure, types, application examples, etc.) ■ Case studies (Can it detect a 0.3mm fine wire? Achieving a 95% weight reduction? etc.) ■ Featured products (Reflective photosensors capable of color discrimination with high resolution) *The case studies mentioned are included in the 'Photosensor Problem-Solving Case Collection Vol.1', which can be viewed via the "PDF Download" link below.

[Material] Beginner's Edition: Introduction to Photo Sensors

[Material] Beginner's Edition: Introduction to Photo Sensors

Introducing the basic structure of photo sensors, as well as the types of photo sensors!

A "photo sensor" is an electronic component that detects light emitted from a light source and converts it into a signal. It reads the changes in the signal caused by an object obstructing the light path (the path of light) and makes a judgment based on that. Using light for detection offers a significant advantage of non-contact detection of the target. On the other hand, it also has the disadvantage of being difficult to use in environments with stray light, making it a behind-the-scenes presence that is often used in many places around us but not easily noticed. This document provides a clear explanation of the basic structure of photo sensors, the types of photo sensors, their characteristics by type, and application examples. [Contents] ■ Basic structure of photo sensors ■ Types of photo sensors ■ Characteristics by type and application examples ■ The option of customization *For more details, please refer to the PDF document or feel free to contact us.

A photoreflector that uses an infrared light-emitting diode on the emitting side and a modulated phototransistor light-receiving element on the receiving side.

The KR3610 reflective photo sensor with light modulation type is a dustproof photo reflector that uses an infrared light-emitting diode on the emitting side and a modulated photo IC light-receiving element on the receiving side. Its dustproof structure makes it easy to remove paper dust and allows for the detection of materials with low reflectivity, such as black paper and OHP film. Due to its light modulation method, it is resistant to noise from ambient light and other disturbances. It has a wide detection range and is a low-cost option. It is suitable for applications such as paper detection in copiers, printers, and various automatic machines for object passage detection. For more details, please contact us or refer to the catalog.
