When it comes to safety light curtains, we all know that it is a protective device applied to some high-risk equipment. However, with the continuous development of Chinese science and technology, the style of mechanical equipment is constantly emerging, which has led to the installation of safety gratings in some equipment The location is very tricky and requires special customization to install it, which greatly increases the cost.
The small and exquisite safety light curtain can greatly reduce this situation. It can be simply modified according to the requirements of the equipment, so that it can meet the installation requirements of many mechanical equipment.
Dadi QB series of compact safety gratings have small appearance, high precision, and strong signal transmission and reception capabilities. The control principle is that the light signal emitted by the transmitter is directly received by the light receiver to form a protective light curtain. The light receiver monitors the on-off state of the light curtain, and processes the on-off signal of the light curtain through the internal circuit to directly output low-frequency (on-off) signals. Light time) or high power frequency (light time), connected to the PLC or alarm circuit through the transmission line to achieve equipment stop or safety alarm.
