Safety light curtains
Safety light curtains are a common type of industrial safety equipment used to protect people and equipment from hazardous areas. The way the gratings emit through determines how they detect the presence of objects or people. In this article, we will introduce two common safety light barrier beam methods: through beam and diffuse reflection, and analyze their characteristics and applications.
Safety light curtainsFirst, the through-beam safety grating is a kind ofTransmitter and receivercomposed of optoelectronic devices, they are installed on both sides of the danger zone. The transmitter emits a beam of light onto the receiver, forming a ray of light. When an object or person enters between the rays, the beam is blocked, triggering an alarm or stopping the operation of the device. The advantages of through-beam safety light curtains are that they are easy to install, suitable for large areas and require high occlusion. The more popular model on the market is the ESN series of safety light curtains, which is the case.
Second, the diffuse reflective safety grating is to connect the transmitter and receiverIntegrated in the same unit, the transmitter transmits the beam to the area to be monitored, while the receiver receives the returned beam. When the beam is obscured by an object or person, the receiver triggers an alarm. The advantages of the diffuse safety light curtains are that they are easy to install, are suitable for use in space-constrained locations and do not rely on precise alignment of the beam position.
IIIThrough-beam and diffuse safety light curtains need to be considered for use when they are being used. Through-beam safety light curtains are suitable for situations where an entire area needs to be monitored, such as large machinery, entrances and exits, etc. However, through-beam safety light curtains place high demands on the installation location and occlusions, requiring greater care during installation and maintenance.
Fourth, in contrast, the diffuse reflection safety light curtain is more suitable for smaller areas and limited spaces. It does not require precise alignment on both sides, saving time in installation and adjustment. However, since the degree of reflection of the beam on the surface of an object can be affected by the surface properties, a diffuse reflective safety light barrier is usedThe adaptability of the light needs to be considered.
There are two main types of through-beam emission modes of safety grating: through-beam and diffuse reflection. The through-beam type is suitable for large areas and occasions where the cross-beam position is accurately located, while the diffuse type is suitable for smaller areas and places where space is limited. When choosing a safety light curtain, it needs to be based on the actual application requirements and site conditionsThe characteristics and advantages of the two receiving methods are comprehensively considered to ensure safety in the industrial production process. In the future, as technology advances, the way safety light curtains receive may be further innovated and more options will be provided to meet the needs of different industrial environments.
