PN SI-108 Dual
Dual Wire ESD Wrist Strap and Coil Cord Assembly
United's SI-108 Dual Conductor Wrist Strap Assembly is designed to interface with dual wire, resistance style constant monitors. The wrist strap is easily adjustable, lays flat on the technician's wrist (for optimum performance) and is manufactured from a highly robust, easy care polyester fabric suffused with silver nitride conductive threads for 360 degree conductivity.
Where Dual Wire ESD Wrist Straps are used:
It's EASY to generate a static charge. Static electricity is often generated by the contact and separation of the technician's clothes against their skin or their shoes contacting and separating against flooring as they walk. When static discharges to something of a lower electrical resistance it can devastate micro electronics, munitions and more. A person's skin is moderately conductive allowing the static charge to flow around the human body but to eliminate this charge the skin needs to be continually grounded.
To monitor the grounding efficiency of the skin many clients use a resistance style constant monitor. Many constant monitors rely on a dual path of conductivity. A very small electrical charge is sent through one ground path, across the users skin and is measured for the appropriate resistance via the second conductive pathway and the constant monitor. Should this resistance become compromised the alarm feature of the monitor alerts the technician immediately.
Our ESD SI-108 Dual Wrist Strap feature a conductive strap that makes 360 degree contact with the user's wrist while our heavy duty wrist strap coil cord and hardware insures the static charge is grounded in a fast, efficient and RELIABLE manor.
