Safety grating is a kind of infrared safety protection device. The light emitting device and the light receiver are installed on both sides, and the internal digital program control is carried out by single-chip microcomputer and microprocessor, so that the infrared transceiver unit forms an infrared light curtain warning barrier in the state of high-speed scanning. When people and objects enter the light curtain barrier area, the control system quickly converts the output level signal to control the brake control loop of the machine or the alarm device of other equipment. Realize machine emergency stop or safety alarm; When people and objects leave the curtain warning area, the load automatically closes normally, so as to achieve the purpose of safety protection. Automatic packaging safety grating, choose IPu, good quality, industry recognized brand. The working principle of the safety grating: The safety grating is composed of two parts: the light emitting device and the light receiving device. The light emitting infrared light is received by the light receiver, forming a protective light screen network, when there is an object into the protective net or is blocked, through the internal control line, the light receiver circuit immediately respond, that is, output a signal to the machine, so that the machine stops running or safety alarm, better protect the operator's personal safety. Safe production, you need a reliable security product; Choose IP to give you better protection. Safety grating selection guide: Step 1: Match the product type according to the use scenario and demand; Step 2: Select the height you want to protect. Step 3: Select the protection part (the choice of optical axis spacing); Step 4: Select the output type you want to match.
