Jewel® MagSnap Wrist Straps meet or exceed the requirements of ANSI/ESD S20.20 and
ANSI/ESD S1.1 including section 5.4 Breakaway Force “With the ground cord connected to
the cuff in a normal manner, a force of ≥ .45 kg (1 lb) but ≤ 2.3 kg (5 lb) applied to the ground
cord, in the normal disconnect direction, shall be required to separate the ground cord from
the cuff.”
Per ANSI/ESD S20.20 Paragraph 6.2.2.1. Personnel Grounding Requirements “All personnel
shall be bonded or electrically connected to ground or contrived ground when handling ESD
sensitive items. When personnel are seated at ESD protective workstations, they shall be
connected to the common point ground via a wrist strap system.”
“At first glance, the ground cord appears to be a relatively simple assembly. However, the
design requirements are considerable, given the wide range of user applications and the
durability requirements of constant tugging, flexing, and dragging over the edge of workstation
tops and equipment chassis.”
(ESD Handbook TR20.20 paragraph 5.3.2.2.2 Wrist Strap Ground Cord)
NOTE: Complete wrist strap kits include an alligator clip. Wrist strap kits include an alligator
clip for occasions when a grounded banana jack is not available. However, “Wrist strap
ground cords must be connected to a groundable point or an equipotential bonding point. Do
not connect to a snap on a dissipative mat unless it is the groundable point for the mat. Do not
clip a wirst strap to the edge of a dissipative mat.” (ESD Handbook TR20.20 section 5.3.2.7)
ESD Handbook TR 20.20 paragraph 5.3.2.4.4 Test Frequency “Because wrist straps have a
finite life, it is important to develop a test frequency that will guarantee integrity of the system.
Typical test programs recommend that wrist straps that are used daily should be tested daily.
However, if the products that are being produced are of such value that knowledge of a
continuous, reliable ground is needed, and then continuous monitoring should be considered
or even required”
Continuous Monitors pay for themselves improving quality, productivity, eliminating wrist strap
daily testing and test result logging. Per ESD-S1.1 paragraph 6.1.3 Frequency of Functional
Testing “Daily (Wrist Strap) testing may be omitted if constant monitoring is used.”

• Revolutionary magnetic interconnect technology
Creates magnetic connection between wristband and coil cord; meets ANSI/ESD S20.20 and ESD S1.1,
including disengagement force test (1-5 lbs). More consistent disengagement force than standard 4 mm
designs.
• Dual-wire wrist strap provides redundancy
If one dual wire wrist strap condutor is severed, operator still has reliable path-to-ground with other wire
• 3.5 mm mono plug compatible with 3M and other brand Continuous Monitors
• More reliable design
MagSnap revolutionary design provides consistent retention and release performance.
• Premium metal expansion wrist strap
Comfortable, designed not to pinch or pull hair
• Durable metal band
Long wearing, easy to clean
