There are various safety light curtains on the market today. The parameters related to the selection are the resolution. We all know that the resolution is calculated in millimeters mm. The common safety light curtain spacing is 5mm, 10mm, 15mm, 20mm, 40mm. , 60mm. At this time, the distance between the two optical axis points of the safety light curtain.
    Because of the different resolutions, the safety light curtains are also referred to as fingers and palms, arm and body protection types to represent the most appropriate application, but this intuitive classification is often perceived as a false perception. Many designers believe that the type of light curtain can be directly selected according to the human body part that causes damage from the source of danger, but such selection method often does not meet the requirements of the standard.

      According to the European standard ENISO1385, the minimum distance of the safety light curtain from the dangerous source should be introduced into the formula and calculated as the parameters of the resolution of the light curtain, the installation method, and the stop response time of the system. Vertical installation, horizontal installation and installation with tilt angle have different formulas. Only considering the resolution of the light curtain, the positioning method, the stop response time and the distance from the dangerous source are the correct methods to meet the standard.

      For example, some equipment light curtains choose the palm protection type according to the speed matching method. Once the light curtain is limited from the dangerous source, or the system stops responding for too long, you should consider increasing the light curtain resolution to meet the European ENISO13855.
