RFID Silicone Wristbands

Compare the shape. Check the dimensions.

RFID silicone wristbands carry a contactless chip and antenna inside a molded wearable. This catalog includes closed loops, adjustable straps and buckle styles, plus a separate insert component. Compare each model’s drawing dimensions and nominal weight, then choose the chip and encoding accepted by your access reader, phone application or venue platform.

Technical overview

The size on the drawing has a specific meaning.

A closed-loop opening, an open strap length and a finished wrist circumference are different measurements. Start with a model, then check fit on the intended wearers.

Body & shape
Molded silicone wristband references. WB-001–005 are closed-loop designs; the remaining wearable codes show adjustable or buckle constructions. WB-034 is a separate insert.
Closed-loop example
WB-003: opening across 55 / 65 / 75 mm; front width 17 mm; rear band width 13 mm. Nominal catalog weight 9 g.
Adjustable example
WB-013 / WB-014: open length 255 mm, front width 27 mm, centre profile 5 mm. Nominal catalog weight 25 g.
Electronic assembly
Chip and antenna selected together for the model and reader. Catalog band options are LF / HF / UHF; WB-003 lists HF and WB-034 lists HF / UHF.
Surface marking
Catalog references include silkscreen, laser engraving and color filling. Confirm artwork, marked area and surface finish for the selected model.
Use conditions
Define water exposure, cleaning agents, temperature and reuse cycle for the complete assembly. Test criteria and any applicable reports are confirmed for that configuration.

Original dimension references

Four shapes. Four different fit decisions.

These are original catalog illustrations. Open a drawing to read it at full size. Every model in the catalog below has its own drawing link.

WB-003 original catalog dimension drawing. Opening across: 55 / 65 / 75 mm; front width: 17 mm; rear band width: 13 mm.

WB-003 Closed loop

Opening across: 55 / 65 / 75 mm; front width: 17 mm; rear band width: 13 mm.

Three opening sizes, plus separate front and rear widths. Check hand clearance as well as wrist fit.

WB-006 Adjustable strap

Overall length: 240 mm; widest section: 19 mm; centre profile: 7 mm; outlined face: 35 × 15 mm.

The 240 mm annotation measures the open strap. The fitted circumference also depends on overlap and the selected hole.

WB-013 Adjustable strap

Overall length: 255 mm; front width: 27 mm; centre profile: 5 mm.

A broader 27 mm face on a 255 mm open strap. Its 5 mm centre profile is a separate measurement from width.

Dimensions are source annotations, not a finished-size tolerance. The WB-034 illustration shows a separate insert; it does not include a complete strap or closure.

Reader & chip selection

Select the interface your application actually uses.

A model code identifies a shape. It does not identify an installed chip or guarantee a working hotel, admission or payment credential.

What the reference establishes

Readable model dimensions, pictured closure construction and nominal catalog weights. An opening measurement is kept separate from strap length, face width and profile thickness.

What the order drawing adds

Current size options and tolerances, fitted circumference, closure behavior, chip and antenna, marking position and any agreed environmental test criteria.

Source documents & scope

Original model catalog archive (retained for source review) — pages 2–18 supply the drawings and nominal weights. General temperature statements and certification symbols in that archive are not treated here as proof for every finished assembly.

Silicone RFID Catalog: 34 Model Codes

Dimensions below reproduce readable catalog drawing annotations, and weights are nominal catalog values. They are selection references, not production tolerances or current stock availability. The order drawing defines the selected size, closure, chip assembly and finished weight. LF / HF / UHF labels describe catalog options; each band is supplied with an agreed electronic configuration.

Dimensions are in millimetres. “Opening across” is not wrist circumference; “overall length” means the open strap. WB-034 is an insert component.

Silicone RFID wristband questions

Is a 255 mm strap suitable for a 255 mm wrist?

The 255 mm dimension shown for WB-013, WB-014 and WB-017 is the overall open-strap length. The fitted circumference is smaller because the strap overlaps at the closure. Confirm the hole positions, fastening allowance and fitted size range on the order drawing, then try a sample on representative wearers.

How do I choose a closed-loop silicone wristband size?

Use the opening dimension on the model drawing as a starting point. For example, WB-003 shows opening measurements of 55, 65 and 75 mm across the loop, a 17 mm front width and a 13 mm rear band width. These are not wrist circumferences. Check both passage over the hand and comfortable fit on the wrist with a physical sample.

Does every model support LF, HF and UHF at the same time?

No. Those labels are catalog frequency options, not a promise of three radios in one wristband. WB-003 is listed as HF; WB-034 is listed as HF / UHF. Confirm the exact chip, antenna and mold together. Reader compatibility, phone behavior and read distance depend on the finished configuration.

Can a silicone wristband operate our hotel locks or cashless platform?

Provide the exact lock or reader model, the platform’s accepted chip and its encoding requirements. The same radio frequency does not establish application compatibility. An NFC URL tag can open a phone link; a room-access or venue-account credential needs the appropriate system configuration. Test a personalized band on the actual platform before bulk approval.

Are the illustrated silicone bands waterproof or suitable for chlorine?

The catalog pictures and silicone material name do not establish an IP rating or chemical-resistance result for a finished assembly. Specify immersion depth and duration, water chemistry, cleaning agents and intended temperature. Request the applicable test evidence for the selected model and check RF operation, print and closure after the agreed exposure.
