A fundamental principle of ESD control is to ground conductors, including people at ESD protected workstations. Wrist straps are the first line of defense against ESD - they are:
- the most common personnel grounding device used and
- required to be used if the operator is sitting.

Dual-wire wrist straps offer a reduced risk of damaging ESD sensitive devices in critical applications. For maximum benefits use dual-wire wrist straps together with dual-wire continuous monitors. Advantages of using dual-wire wrist straps:
1. Eliminate intermittent failures
2. Extend lifespan of wrist strap

An important feature of dual-wire wrist straps is that even if one conductor is severed, the operator has reliable path-to-ground with the other wire. The continuous monitor used with the wrist strap will alarm. However, the operator will still be grounded by the other wire. So there is a significantly reduced risk of damaging the product if the operator happens to be handling an ESD sensitive component when the wrist strap fails.

Jewel® MagSnap Dual-Wire Wrist Straps
create a magnetic connection between the wristband and coil cord. This allows for a more consistent disengagement force compared to standard 4mm designs. The 3.5mm mono plug is compatible with SCS and other brand continuous monitors. The MagSnap revolutionary design provides consistent retention and release performance. Jewel® MagSnap Dual-Wire Wrist Straps are supplied with a comfortable, adjustable wristband which is made of silver suffused monofilament conductive interior. The wristband reliably removes generated static charges and is hypo-allergenic. It is also adjustable meaning only one item has to be stocked that can be fitted to almost all people. The locking clasp protects wearers from electrical hazards and provides many years of product life.
