• Revolutionary magnetic interconnect technology
  Creates magnetic connection between wristband and coil cord; meets ESD S1.1, including disengagement force test (1-5 lbs)
• More reliable design
  Socket removed, whose miniature springs can wear and fail
• Durable, lightweight fabric
  Some users prefer the softness, comfort and flexibility of this material
• Has silver impregnated nylon knitted on inside for superior conductivity
  Reliably removes generated static charges
• Made with pure silver irreversibly bound to fibers providing both antimicrobial and anti-odor performance.
• Adjustable
  Only one item to stock; may be fitted to almost all people
• Locking clasp
  Band locked so it will not slip
• Unique patented** adjustment design eliminates exposed conductive “tail” of band
  Provides added safety eliminating chance of providing inappropriate ground path
• Medical grade 300 series stainless steel used for all metal parts
  Eliminates allergic skin reaction for most people
• Non-shedding, non-sloughing band material
  Safe for microelectronics
• UL Listed - coil cord includes 1 megohm resistor
• Date coded
  Providing lot tractability to ensure quality control
• Superior resistor connection strain relief
  Superior reliability. Greatly exceeds ESD S1.1 Bending Life Test. Tested at over 1,000,000 cycles vs. the 16,000 requirement
• Made in the United States of America

What the ESD Association says about testing wrist straps:

Per ESD Handbook TR20.20 section 5.3.9.1 Wrist Strap Checkers - “Wrist strap checkers have historically been the primary tool for testing the operation of the wrist strap system including, the wristband, grounding cord and most importantly, the electrical integrity of the contact between the wristband and the wearer. Wrist strap checkers measure the resistance of the entire system.”

Circumference - 2.5" - 14"
NOTE: All bands have a 4mm snap stud. 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, best industry practice is that ESD Ground Connections should be firm fitting connecting devices such as metallic crimps, snaps and banana plugs to be connected to designated ground points. Use of alligator clips is not recommended. (Ref: JEDEC Standard No. 625-A)

Jewel® Wrist Bands meet and exceed the Wrist Band and Wrist Cord requirements of ANSI/ESD S20.20

ANSI/ESD S20.20 Paragraph 6.2.2.1 Personnel Grounding Requirement "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 via a wrist strap system."
