ESD Bin Shelves for Industrial Racking

When ESD bins beat plain plastic bins

If your shelving is in an ESD Protected Area (EPA) or you store any non-bagged ESD-sensitive components (bare ICs, raw PCBs, unbagged sub-assemblies), plain plastic bins are an ANSI/ESD S20.20 violation — full stop.

ESD bin shelves replace plain plastic bins one-for-one in standard shelf systems. They look the same, mount the same, but the polymer is carbon-loaded dissipative PP at 10⁴-10⁹ Ω/sq, so any tribocharge picked up by the operator drains through the bin to the grounded shelf.

Sizes and rack compatibility

Small (175 × 110 × 75 mm) — small parts, screws, fasteners, individual ICs.

Medium (270 × 150 × 125 mm) — sub-assemblies, kits, components in cut tape.

Large (415 × 200 × 175 mm) — PCBs, modules, larger components.

Jumbo (540 × 305 × 220 mm) — full PCB sets, multi-PCB kits.

All sizes fit standard wire-shelf and steel-shelf racking on 18", 24", 36" and metric spacings.

5S color coding

Black (default) — general inventory.

Blue — incoming / receiving / not yet inspected.

Red — quarantine / rework / NCR holds.

Yellow — kitting and WIP.

Custom colors quoted at 500-piece MOQ.

All non-black colors use color masterbatch blended with the carbon-loaded dissipative compound, so the ESD rating is identical to the black baseline (carbon by itself is what gives the bin its conductivity — adding pigment does not affect it).

Grounding the rack

Bins are dissipative, not isolating — they drain charge to whatever they touch. To complete the EPA, the rack itself must be grounded to the same potential as your wrist-strap ground and your floor mat.

Steel racks: bond one upright to building ground with a 16 AWG wire. Wire shelves: bond the shelf wire directly. Plastic-coated shelf liners block grounding — remove them or use uncoated wire shelves where ESD bins sit.

Frequently Asked Questions

Do I need to ground the shelf for ESD bins to work?

Yes for full EPA compliance. The bin is dissipative (10⁴-10⁹ Ω) but charge has to go somewhere — without a grounded shelf, the bin floats and any built-up charge stays. For a true ANSI/ESD S20.20 storage zone, bond the rack to the same ground used by your wrist straps and floor mats.

Can ESD bin shelves replace my existing plain plastic bins one-for-one?

Yes — our sizes match the dominant industry-standard footprints (175×110, 270×150, 415×200, 540×305 mm). Drop-in replacement with the same shelf clips. The only thing you change is the bin itself; the shelving stays.

How long do ESD bin shelves last?

Permanent dissipative PP holds its ESD rating for the life of the bin — typically 7-10 years in normal warehouse use. Failure mode is usually mechanical (cracked hopper front from rough use) before electrical.

Do you offer dividers inside the bins?

Yes — slot-in PP dividers in 2-section, 4-section, and 8-section configurations for the medium, large, and jumbo sizes. Useful when you need to keep multiple part numbers in one bin location.
