ESD wrist straps are personal grounding devices that bond an operator’s body to a known ground point via a 1 MΩ current-limiting resistor, safely draining electrostatic charge before it can damage sensitive electronics or semiconductors. Phil Industries supplies 55+ ESD wrist strap SKUs in Singapore — adjustable fabric and metal bands, single-conductor and dual-conductor coiled cords, continuous-monitoring stations and full grounding kits — with ex-stock availability for next-day delivery. Last updated: 17 May 2026.
All wrist straps are sourced from manufacturers whose products meet ANSI/ESD S1.1, IEC 61340-4-6 and ANSI/ESD S20.20 where applicable. Certificates of Conformance and resistance test reports are available on request for IPC and aerospace audits.
ESD Wrist Strap Range
- Adjustable fabric wrist bands — elasticated conductive yarn band with snap stud, sized for most adult wrists.
- Metal expansion wrist bands — stainless-steel link bands for heavy-duty rework benches.
- Coiled grounding cords (single-conductor) — 5 ft and 10 ft coiled cords with built-in 1 MΩ resistor and banana-plug or alligator-clip termination.
- Dual-conductor cords — redundant ground path required for continuous-monitoring systems.
- Continuous wrist-strap monitors — single- and dual-operator monitors that alarm if the strap fails or the operator loses contact.
- Wrist-strap test stations — wall- or bench-mount testers that verify strap resistance at the start of each shift.
- Heel grounders, toe straps and ESD footwear straps — alternative or complementary grounding for standing work.

Frequently Asked Questions — ESD Wrist Straps
Why does an ESD wrist strap need a 1 MΩ resistor?
The 1 megohm resistor is a current-limiting safety feature. It allows static charge to bleed slowly to ground but prevents a dangerous current path through the operator’s body if the strap accidentally contacts a live circuit. ANSI/ESD S1.1 requires this resistor in every compliant wrist strap.
How often should an ESD wrist strap be tested?
Industry best practice (ANSI/ESD S20.20) is to verify wrist-strap resistance at the start of every shift using a dedicated test station, or continuously using a wrist-strap monitor. Logs should be kept for audit. Strap and cord assemblies should be replaced every 6–12 months depending on use intensity.
What’s the difference between single-conductor and dual-conductor coil cords?
A single-conductor cord has one wire from the wrist band to ground — adequate for general electronics assembly. A dual-conductor cord has two redundant wires and is required for continuous-monitoring systems, since the monitor checks each conductor independently to detect a broken ground path.
Are fabric or metal wrist bands better?
Fabric bands are more comfortable for long-shift assembly work and are the most common choice. Metal expansion bands have lower resistance and faster bleed-off, preferred for rework, repair and field-service technicians who switch tasks often.
