The ESD wrist strap is made of soft elastic conductive band, coiled PU or PVC cord, 1Mega ohms resistor and a grounding clip for secure connection. It provides a simple method for dissipating user-generated static electricity, to help protect sensitive electronic equipment from damage during assembly, repair, and transport.The corded wrist strap is the most basic and widely used essential product in the production line of anti-static equipment. It is not only very convenient in erection and operation, but also the most affordable in price. Its principle is to discharge the static electricity on the human body to the ground through the wrist strap and ground wire. Therefore, the wrist strap must be in contact with the skin during use, and the ground wire must also be directly grounded, and ensure that the ground wire is unobstructed to play the maximum effect.
