Wide-Slot Photoelectric Sensor

Product Introduction

Wide-Slot Photoelectric Sensor is a high-performance and high-stability photoelectric detection device designed for industrial automation, logistics sorting, packaging machinery and other fields. The sensor adopts a wide groove structure design, suitable for detecting large sizes or irregular shapes. It has the characteristics of high sensitivity, strong anti-interference ability, and convenient installation. It can be widely used in various complex industrial environments.

 

Features

Wide groove design: suitable for detecting large size or special-shaped objects, improving detection flexibility.

High sensitivity: Use high-quality photoelectric components to ensure accurate detection and fast response speed (≤1ms).

Multiple detection modes: support for surfing, reflective and diffuse reflection detection, adapting to different application scenarios.

Strong anti-interference ability: built-in filtering circuit effectively suppresses electromagnetic interference (EMI) and optical interference.

IP67 protection level: dust-proof and waterproof, suitable for harsh industrial environments (such as dust, moisture, etc.).

Various output methods: NPN, PNP, relay or analog output (4-20mA / 0-10V), compatible with PLC, microcontroller and other control systems.

Easy installation and maintenance: Modular design, supports quick plug-in and unplugging, and reduces downtime.

 

Product structure and working principle

Structural Design

Wide-Slot Photoelectric Sensor mainly consists of the following parts:

Emitter: Use infrared LED or laser light source to emit detection beams.

Receiver: a high-sensitivity photoelectric receiver that detects light signals blocked or reflected by objects.

Wide groove structure: open groove design, easy for large-sized objects to pass through the detection area.

Signal processing circuit: Integrated amplification, filtering and logic control to ensure stable output.

Housing material: high-strength ABS engineering plastic or metal housing (optional), impact-resistant and corrosion-resistant.

 

How it works

The sensor is based on photoelectric detection technology, and its main working modes include:

Through-Beam

The transmitting end and the receiving end are installed separately, and the light beam is blocked when the object passes through, triggering the signal output.

Suitable for long-distance detection (up to 5-10m), with strong anti-interference ability.

Retroreflective

The transmitting end and the receiving end are integrated in the same module to reflect the light beam through the mirror.

When an object enters the detection area, the reflected light is blocked or weakened, and the sensor outputs a signal.

Diffuse

Directly detect light reflected by objects without mirrors.

Suitable for short-distance detection (0-1m), easy to install.
