Product Details

The 240 Series Anti Static Wrist Strap provides premium, reliable Electrostatic Discharge (ESD) protection for personnel working with sensitive electronic components. Engineered for both comfort and performance, this adjustable wrist strap ensures static electricity is safely and continuously channeled away from your body to ground.

Key Features

  • Superior Conductivity: Hypoallergenic, silver-suffused nylon threading is woven throughout the fabric band to capture static directly from the skin’s surface at a highly conductive rate.

  • Surgical-Grade Contact: Features a curved, surgical-grade stainless steel backplate that contours comfortably to the wrist, maximizing skin contact while minimizing irritation.

  • Secure Connection: Equipped with a standard 4mm stud snap on the wristband, providing a secure and reliable attachment point for your grounding coil cord.

  • Comfortable & Adjustable: The elastic fabric band easily adjusts to fit a wide range of wrist sizes snugly and comfortably for all-day wear.

Pro Tip for Optimal Performance: For maximum ESD protection, ensure that the wristband has direct contact with the skin. Do not allow clothing, such as an ESD smock sleeve, to get between the strap and your wrist.

Coil Cord

On the outside, the cord is made of polished polyurethane (PU) that is static dissipative.

On the inside, the encapsulated 1 meg ohm resistor ensures that electrons are transferred through the cord to ground at a static dissipative rate.

Static electrons collected off your body by the wrist strap are transferred to ground by attaching the coil cord to grounding:

a wrist strap ground, or a common point ground.

Alternatively, you can clip the coil cord to a metal railing with the included alligator clip (which slides over the plug).

1 Meg Ohm Resistor

A 1 Meg Ohm Resistor is built into the coil cord to slow down an electrostatic discharge event (ESD) from a highly charged ungrounded surface from discharging instantaneously through the coil cord.

Typically a 1 Meg Ohm Resistor slows down an electrostatic discharge (ESD) a few more milliseconds than if it were not present.
