Safety gratings are also photoelectric safety protection devices (safety protectors, punch protectors, infrared safety protection devices, etc.). Generally speaking, safety gratings exist in pairs, which are divided into transmitting ends and receiving ends. Line synchronization optical synchronization mode is adopted, and safety gratings exist in pairs. It is composed of a set of transmitters and receivers, the transmitter will transmit a set of infrared beams, and the receiver will include many light sensors. If the object is between the transmitter and the receiver, the receiver does not receive a complete signal and will send a stop signal to the monitoring device.

According to the provisions of the international standard IEC61496, relevant requirements are put forward for the design, structure, and testing of the fourth and second levels, respectively, to ensure the relevant functions of safe products. The main features of the secondary light curtain are: low cost, single CPU processor, dual safety channel output, to meet the safety requirements in the way of periodic self-check, a fault may lead to the loss of the safety function, but it can be detected in the next cycle Out, the technology used is a periodic self-checking single loop. The main features of the four-level safety light curtain are the use of dual CPU processors, dual safety channel output, reliable control of the four-level control, and superior performance. Using guaranteed safety devices and technologies, a failure will not lead to the loss of the safety function, the safety function will always exist, and the real-time self-detection double loop. Secondary safety light curtains are generally used in small, mild, or moderately hazardous situations and protective devices are used in hazardous areas. It can also be used in general automated production equipment, robot workbenches, etc. Class 4 light curtains are generally used in severely dangerous or high-risk equipment and occasions, or places clearly required by local regulations. Safety light curtains and safety grating are generally different names for the same product, so the second-level safety light curtain can also be called the second-level safety grating, and the fourth-level safety light curtain can also be called the fourth-level safety grating.

Safety grating is an advanced technology to protect workers around various dangerous machinery and equipment. Compared with traditional safety measures, such as mechanical fences, sliding doors, pullback restrictions, etc., safety gratings are more accessible, more flexible, and reduce operator fatigue. By reasonably reducing the need for physical protection, safety light grids simplify those routine tasks such as installation, maintenance, and repair of equipment.

G-TEK Sensor safety light curtain sensor LSA is mainly used in mechanical finishing to protect the safety of operators.

Product features at a glance:

1. The unique structural design ensures that there is no blind spot in the entire protection area;

2. Dual-channel OSSD output function, which can be cross-monitored with each other;

3. With self-diagnosis function, it can detect the failure circuit module of the light curtain. and issue an alarm signal;

4. With interlock reset, external test, and EDM function, strengthen the output monitoring ability;

5. Adopt optical communication synchronization, simplify the electrical connection and make the operation easier;

6. Meet the requirements of Type 4, SIL3 and PLe safety level, and can be used for the protection of various parts of the body;

7. Waterproof design to meet outdoor applications.

Safety light curtains are also photoelectric safety protection devices (safety protectors, punch protectors, infrared safety protection devices, etc.). In modern factories, people and machines work together on some potentially dangerous mechanical equipment, such as stamping machinery, Shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, automatic transmission and handling equipment, hazardous areas (toxic, high pressure, high temperature, etc.) are likely to cause personal injury to operators.
