Grounding is the part of an ESD programme auditors check first. Phil Industries supplies anti-static grounding kits, earth bonding plugs, coiled wrist cords, heel straps and continuous monitors in Singapore — sized for one bench or a whole line.
🔌 Which grounding part do you need?
| Accessory | Grounds | Best for | Notes |
|---|---|---|---|
| Grounding kit | Operator + surface | New single workstation | Fastest route to a compliant bench |
| Earth bonding plug | Mat / bench | Common-point ground | Takes multiple studs |
| Coiled wrist cord | Operator | Seated assembly | Replaceable wear part |
| Heel straps | Operator | Standing lines, visitors | Needs ESD flooring to work |
| Wrist strap + monitor | Operator | Audited / high-value work | Alarms on failure |
📊 Why 1 MΩ sits in the cord
Role of the current-limiting resistor
| No resistor |
|
Charge drains fast, operator unprotected |
|---|---|---|
| 1 MΩ in series |
|
Charge still drains, current limited |
| Insulated / broken cord |
|
No path — charge accumulates |
Schematic comparison, not measured data. The 1 MΩ resistor limits current if the operator contacts live mains while wearing the strap.
🏷️ Anti-static grounding — same job, different name
Anti-static grounding, ESD earthing and electrostatic discharge grounding all describe the same thing: giving charge a controlled path to earth. Search terms differ; the hardware does not.

❓ Common questions
What is in an ESD grounding kit?
Typically a dissipative mat, a common-point ground cord and a wrist strap with coiled cord — everything needed to make one bench compliant.
Why is a 1 MΩ resistor used in grounding cords?
It limits current if the operator touches live mains while strapped. Charge still drains; the operator is protected.
Do heel straps work on any floor?
No. They need ESD footwear logic — a dissipative floor to complete the circuit.
Do you stock grounding accessories in Singapore?
Yes. Kits, plugs and cords are held locally with same-day quotation.
