ESD Wrist Straps, also known as Antistatic Wrist Straps, are used to prevent electrostatic discharge (ESD) by safely grounding a person working with electronic equipments or at an electronic assembly facility. They are usually used in conjunction with an ESD mat on the workbench, or a special static-dissipating plastic laminate on the workbench surface.  

Prodauct description:

Economic elastic Wrist Strap is composed of elastic wrist loop and grounding wire, the elastic wrist loop contact with 

skin directly, sand form an anti-static channel together with hardware plate and coil core buckle connection, this channel 

transfer away static from skin.

Coil core is made of circling wire, space minimum occupied, and has good retractility. Every ground coil core has safety 1MΩ resistance, it protects operators safety as well as current-sensing devices.

Main material:

1. Plastic piece material:  ABS (sky blue)  
2. Hardware piece material:  304 (stainless steel)  
3. Catapult wire material:  PU (sky blue)  
4. Catapult wire core:  7 root copper foilsilk  
5. Fastener material:  Fe (nickel plate)  
6. Conduction strap material:  Nylon    
7. Four petal banana pin:  Fe (nickel plate)

General Parameters:

1. Discharge period: <0.1S (1000V~100V)

2. Buckle pulling-out force: F>0.45Kg (1Pound), F<2.3Kg (5Pounds)

3. Elongation of coil wire: can elongate at 80% of its total length

4. Wrist band inner side surface resistance: ≤1KΩ

5. Coil core safety resistance: 1MΩ±5%

6. Coil core bending times: >2000000 times

7. Coil core hanging force: 13.61 Kg (30Pound)

8. Plug life span: ≥10000 times

9. Plug pulling-out force: F≥454Kg (11Pound)

10. The diameter of Snap is 10mm, the cord length is 8 inch

Usage Instruction:

1. Place the wristband of the anti-static wrist strap around your bare wrist.

2. Secure the wristband so that the metal plate on the inside of the band is firmly pressed against the underside of your arm. The metal plate should have as much contact with your skin as possible, so place it in the spot where you have the least amount of hair.

3. Connect the strap to the wristband. The strap and wristband usually connect via a simple snap mechanism.

4. Clip the alligator clip on the end of the strap onto an anti-static mat or any bare metal surface that is touching the ground.
