A Chrome-Plated iButton Probe Reader That Solves Common Field Failures
When a door station stops recognising keys, the reader head is usually the cause, and a site visit costs far more than the part. This probe is designed around the three problems installers report most.
Keys stop reading after a year or two. Oxidised contacts are the typical culprit. Here the zinc alloy contacts carry a chrome-plated layer that resists oxidation and wear, so read quality holds up over years of daily touches.
Replacement readers don't recognise existing keys. The probe reads 1990, 1991, 1996 and 1961 iButton devices, so you can swap or add readers on a live site without reissuing credentials.
One enclosure needs a panel mount, the next needs a board-level part. The same touch memory probe fits either way, which keeps one part number on your BOM across projects.
Why Integrators Buy This Wholesale iButton Probe Reader for Multi-Site Projects
Fewer service calls per site
Stable contact means fewer "key not reading" tickets. On a rollout of hundreds of doors, that is the difference between a quiet maintenance contract and a truck roll every week.
Users line up the key without looking
The round probe face matches the circular iButton package, so the key centres itself on contact. Residents and staff need no instruction, and partial contact misreads drop.
Light enough to ship in volume
At 24 g per unit and 100 pieces to a carton, a thousand probes travel as ten compact cartons, which keeps air freight affordable when a project deadline moves up.

Zinc alloy contact points
Strong, conductive and corrosion-resistant, so data transfer stays consistent even at busy entrances and shift-change time clocks.
Chrome-plated wear layer
The plating takes the wear of repeated key touches and blocks oxidation, which is what extends the life of the reader head.
Stainless steel housing
Waterproof, dustproof and corrosion-resistant, protecting the internal circuit at outdoor gates, warehouses and exposed equipment panels.
Eco-friendly plastic parts
Used on non-contact components to keep the probe light and durable while meeting environmental standards.
Chrome-plated contact ring and stainless steel body.
Project-Ready iButton Reader Probes for Access Control, Asset Tracking and Data Logging
Door stations and intercom panels
Residents present a TM key at the entrance and the reader passes the ID to the controller. Panel mounting keeps installation quick on new builds and retrofits.
Asset and equipment tracking
Fixed read points on equipment or checkpoints record which key touched and when. A sealed metal reader survives handling that would damage card readers.
Data loggers and controllers
Welded to the board inside loggers and terminals, the probe identifies the operator before data is recorded or uploaded.
Logistics and medical devices
Operator sign-in on logistics equipment and access control on medical devices, where the reader must tolerate frequent cleaning and handling.

Most buyers choose this zinc alloy version for public-facing or exposed installations where contact wear and corrosion matter. If your device sits indoors and you prefer a plastic body, see our ABS probe reader for TM cards. Not sure which fits? Send your application details and our engineers will recommend one.
| Your situation | Recommended setup |
| Outdoor gate, lobby or high-traffic entrance | Zinc alloy probe, panel mount |
| Vibration or tamper risk | Zinc alloy probe, welded to control board |
| Enclosure needs a different lead length or shape | Custom build (see OEM service below) |
| Replacing readers on a site with existing keys | Standard probe, compatible with 1990 / 1991 / 1996 / 1961 keys |
Custom TM iButton Probe Reader Manufacturing for OEM Device Makers
If the standard part doesn't fit your enclosure, we change it rather than asking you to redesign. Customization covers:
✓Appearance to match your panel finish or product styling
✓Size and lead length set to your housing and connector position
✓Installation method configured for panel mount or board weld
To quote a custom build quickly, send your panel drawing or cut-out size, the lead length you need, the mounting method and your annual volume.
Need keys as well? Pair the probe with RW1990 iButton TM cards or TM1990A-F5 iButton tags from the same factory, so the full set is checked together before it ships.
Standard probe, ready to adapt for OEM builds.
Factory-Tested iButton Probe Readers Backed by ISO9001 and CE
Every Syntek iButton probe reader is produced under an ISO9001 quality management system, with CE certification for the range and an ISO14001 environmental system at the factory. Importers and security distributors sourcing from an iButton probe supplier in China can use these documents for customs clearance and tender pre-qualification.
Certificate copies are available on request with your quotation.
Bulk-Order iButton Probe Packaging and Export Shipping
Probes are packed 100 pieces per export carton at 3.5 kg gross weight. The low unit weight keeps both sea and air shipments economical, and cartons stack cleanly for wholesale distributors who hold stock of iButton reader parts.
Private labeling and custom packing can be discussed as part of an OEM order.

Procurement Questions About the TM iButton Probe Reader
Q1. Which iButton keys work with this probe reader?
The probe reads DS1990-series touch memory keys and is listed for 1990, 1991, 1996 and 1961 iButton devices. Syntek also manufactures RW1990 and TM1990A keys, so you can order probes and keys together and have them matched before shipment.
Q2. What read distance should I design for?
iButton is a contact technology, so the key has to touch the probe. The effective working gap is about 1 to 3 mm depending on the key model and probe sensitivity. Design your panel so the key seats fully in the probe ring.
Q3. Can the probe be panel-mounted or soldered onto a PCB?
Both. The standard fitting is a flat-panel mount, and the probe can also be welded directly to the control board for sites with vibration or tamper risk. Tell us which method you use and Syntek will configure the probes for it.
Q4. How long does a zinc alloy iButton probe last?
Typical service life is more than five years, depending on how often it is used and where it is installed. The chrome-plated contacts resist oxidation, which is the most common reason touch memory probes stop reading.
Q5. Can Syntek make a custom iButton probe reader for my device?
Yes. As a factory-direct iButton probe manufacturer, Syntek adjusts appearance, size, lead length and installation method to fit your enclosure. Send a drawing or a sample and we will confirm what can be changed.
Q6. Can I test samples before placing a bulk order?
Yes. Syntek provides free samples of the TM iButton probe reader so your engineers can check fit, mounting and read performance before you commit to a wholesale order.
