The Static Wrist Band is a low cost static strap that is perfect for single or low use situations.
Anytime anyone, including guests, are near your sensitive, expensive, electronics, you need them to be static aware and static safe. However, that doesn’t mean that they need a production quality static wrist band. The Limited Life Static Wrist band is a low cost disposable static wrist band that is perfect for handing out to guests, or anyone, who will be working around your electronics for a short period of time.
An anti-static wrist band (properly grounded) should be worn at all times when handling exposed electronics circuitry and components. By wearing this strap, any static charge built-up on the wearer will be dissipated to ground (through a protective 1 Meg Ohm resistor). This ensures that the wearer will be at ground potential and no damage can occur to the electronics.
For optimum protection, a wrist strap should be used in conjunction with a properly grounded anti-static mat .
A static factoid
Did you know that when you feel that tell-tale "ZAP" of static discharge, that your body is discharging over 2,000 volts? Below this voltage, a discharge still occurs, but it is not normally felt by most people. Of course when dealing with low-voltage electronics, even 50 volts is enough to cause permanent damage so you should always ground yourself with a wrist strap. Remember: just because you don't feel the 'zap' doesn't mean you weren't charged to dangerous levels.
