ESD wrist straps and grounding: a complete kit for a production line
PRIMEAG supplies ESD wrist straps, heel straps, ground cords and grounding sockets from VND 12,000 (ex 8% VAT), in stock and delivered in 24–48 hours in Ho Chi Minh City, Binh Duong and Dong Nai. The wrist strap cord has a 1 MΩ resistor, and total person-to-ground resistance is < 3.5×10⁷ Ω per ANSI/ESD S20.20.
What an ESD workstation needs
| Component | Role | Requirement |
|---|---|---|
| Wrist strap + coiled cord | Grounds the seated operator | 1 MΩ resistor in the cord; person-to-ground < 3.5×10⁷ Ω |
| Heel strap | Grounds walking personnel through the ESD floor | Person–footwear–floor < 1×10⁹ Ω (ANSI/ESD STM97.1) |
| Grounding socket / snap on the bench | Plug-in point for wrist straps, connection for the bench mat | Connected to the common ground point |
| Bench mat ground cord | Grounds the ESD rubber mat | 0.5 mm² cord, 1 MΩ resistor |
| Common ground point | Brings all of the station’s cords to one point | Connected to the factory’s equipment ground |
Common audit findings
- Wrist strap worn loose or over the sleeve — the inner surface does not touch the skin and the person-to-ground reading exceeds the limit.
- Coiled cord broken inside the plastic sheath — looks normal but is open-circuit; check at the start of each shift with a wrist strap tester.
- Bench mat and wrist strap connected to two different ground points — potential difference between the person and the work surface.
Not sure your current grounding system passes? PRIMEAG offers a free on-site ESD resistance test in Ho Chi Minh City, Binh Duong and Dong Nai and sends a report of readings by location. New PRIMEAG workbenches already come with a grounding snap and ground cord: see ESD workbenches.
Frequently asked questions
How much does an ESD wrist strap cost?
From VND 12,000 each ex 8% VAT, depending on cord and plug type. In stock, delivered in 24–48 hours in Ho Chi Minh City, Binh Duong and Dong Nai; lead time for large quantities is confirmed with the quotation.
Why must the wrist strap cord have a 1 MΩ resistor?
To discharge static in a controlled way and to limit current if the wearer accidentally touches a live source; connecting directly to ground without a resistor is unsafe.
How often should wrist straps be replaced?
When the start-of-shift tester shows a fail or the cord is broken. PRIMEAG replaces broken cords free within 3 months.
Do you sell a complete kit for a production line?
Yes. Send the number of workstations and PRIMEAG will quote a complete set of wrist straps, grounding sockets and ground cords within 30 minutes.
