Dual-Wire Wrist Strap MagSnap 360 with Metal Expansion Band and 1.8 m Coiled Cord - Desco

Dual-wire wrist straps are the basis for true continuous monitoring of personnel grounding. The Desco MagSnap 360 combines a stainless steel expansion band with a dual-wire coiled cord that attaches magnetically and rotates freely through 360°. Under load the connection releases in a controlled way instead of damaging cord or snap. The family differs only in band size, all versions use the same 1.8 m coiled cord.

Key benefits

• Magnetic connection with 4.4 to 22.2 N perpendicular breakaway force: no intermittent failures, longer service life.
• 360° rotation between wristband and cord for freedom of motion and less strain on the wrist.
• Redundant path-to-ground over two conductors, system resistance below 3.5 x 10⁷ ohms per IEC 61340-5-1.
• Metal expansion band with medical grade stainless steel backplate and links, ideal for low voltage continuous monitors.
• Strain relief tested over 1 million flex cycles, 62 times the minimum requirement per ESD S1.1. Date coded, UL listed.

Applications

Grounding seated operators at ESD workstations with dual-wire continuous monitors or 3.5 mm grounding jacks, in electronics manufacturing, repair and labs.

Standards

Meets the required limits of ANSI/ESD S20.20 and the requirements of ANSI/ESD S1.1, system resistance per IEC 61340-5-1. Test the wrist strap daily or monitor it continuously.
