ESPE safety light curtain is a safety device commonly used in industrial automation to detect the position and movement of people or objects in a specific area. Generally speaking, security grating can be divided into two main modes: linear scanning mode and cross-scanning mode.

1. Linear scanning mode:

Linear scanning security grating is the most common and widely used type. It consists of a transmitter, which emits an infrared beam, and a receiver, which receives and analyzes the state of the beam. In linear scanning mode, the beam is scanned in either a horizontal or vertical direction. When a person or object blocks the transmission path of the beam, the receiver senses the interruption signal and triggers safety protection measures, such as stopping the machine or issuing a warning signal. The advantage of linear scanning is its simplicity and reliability, which is suitable for most security detection needs.

2. Cross-scan method:

The cross-scanning safety grating is improved on the basis of the linear scanning mode. It consists of two linear scanning security gratings, one for horizontal scanning and the other for vertical scanning. By means of cross-scanning, higher detection accuracy and more flexible security area Settings can be obtained. When a person or object enters the protected area, the two gratings simultaneously detect the interrupt signal, thus triggering security measures more reliably. The cross-scanning method is usually used in situations with higher security requirements, such as applications that need to prevent dangerous objects from entering or prevent people from approaching dangerous areas.

In general, the linear scanning mode and the cross-scanning mode are the two common categories of security grating, which are widely used in industrial automation to achieve the security protection of personnel and equipment by detecting the interrupt signal of the beam. The choice depends on the specific application requirements and security standards.
