Smart security products

Safety products

Safety products are in the process of mechanical safety design, installation, and transformation to meet the standards. It plays a very important role. Many people misuse other sensors as safety products. It is known that accidents that have not been able to be prevented are often caused by non-safety products.

safety certificate

The understanding of safety products on hardware is completely different from that of ordinary sensor certification. Therefore, products with regulated safety product certification may be used with confidence.

We can also customize intelligent security products for you, or special security function products you want.

Sensor

Cooperative robot is originally a tool for human interaction and safety, but because people are still worried about the risk of strong collision between human and robot in the field operation, the speed of robot is generally lowered to reduce the collision risk, but this will reduce the efficiency of robot. After the safety warning box is installed, when people enter the preset 2 meters range, they will immediately send a signal to slow down the robot, thus reducing the risk of strong collision. When people leave the early warning range, the robot will immediately return to normal speed, greatly improving efficiency and reducing safety risks.

It plays a very important role, and many people mistake other sensors for safety products, only to know that accidents that have not been eliminated are often caused by unsafe products.security certificateThe understanding of safety products in hardware is completely different from that of ordinary sensor authentication. Therefore, products with regulated safety product certification may be safe to use.We can also tailor smart security products for you, or products with special security functions you want.

Safety Controller

Safety relay / safety controllert is used to build modules of safety circuit systems for many different devices, and can be matched with suitable safety product modules according to the number of safety products and input points.Used in many types of equipmentCertification standards: ISO 13849-1, ISO 13849-2, ISO 62061, IEC 61508 1-7, IEC 60204-1, IEC 60664-1, IEC 61326-1, IEC 61326-1, IEC 61326-3-1, IEC 60947-1, IEC 60947-5-1, IEC 61000-6-2, IEC 61000-6-4 As the most important part of safety loop, safety controller/safety PLC has been recognized by more and more people, but in the process of use, there are still many users who are confused about the differences between safety relay and ordinary relay, so I would like to share them with you here. As we all know, we must remember three words in the concept of safety design:(1) Redundancy (2) Difference (3) Self-detectionHow to construct the safety loop with the reliability above PLd, the safety controller must become an important link. The safety loop consists of safety input, safety control and safety output subsystems, and the safety control including safety relay, safety controller, safety PLC, etc. realizes the safety control function. Designers match different safety controllers to achieve the reliability level of the safety loop according to the number of products at the input end.
