Magnetic Pogo Pin Cable USB-C for Medical and Wearable Devices, 2 / 4 / 8 Pin

Last updated: 7 September 2026

Why Breakaway Matters More Than Convenience

A magnetic connector is often sold on convenience, and that is the smaller half of the argument. The real reason to specify one on a patient-worn or handheld device is what happens when the cable is pulled. A friction-fit plug transmits the whole yank to the socket and then to the PCB behind it; a magnetic pogo pin cable releases at the interface first, so the device stays where it is and the port is not levered off the board. For a monitor worn on a body, a handheld terminal in a clinical cart, an exoskeleton joint or a robot that moves while tethered, that release is the difference between a reconnect and a repair.

How the Interface Works

The device side carries a ring of spring-loaded pins in a housing with a locating feature, so the cable head can only seat one way up. Gold plating on the pins is there for the contact surface: pogo pins make contact through a small, constantly moving point, and a plating that tarnishes will raise contact resistance over the life of the product. Pin counts of two, four and eight are available, chosen by what the device needs to carry, from plain charging to charging plus signal lines.

• 2-pin: charging only
• 4-pin: charging plus signal or sense lines
• 8-pin: charging plus multiple signal lines for docked or instrumented devices
• Gold plated spring-loaded pins in a keyed housing

Breakaway Force and Service Life

The figures quoted by comparable products are a release force of at least 1.5 kg and a mating life of at least 10,000 cycles. We treat both as leads from public listings, not as verified ratings: they are recorded for confirmation below and will be replaced with measured values. The two numbers pull against each other in design terms, because a connector that releases easily is also one that releases when you did not want it to, so the target is worth discussing against how the device is actually worn or carried.

Cleaning and Disinfection

Anything used in a clinical setting gets wiped down, repeatedly, with alcohol-based and similar agents. A jacket that is not chosen for that will go tacky, crack or discolour, and the failure is visible long before it is electrical. The medical-grade silicone and TPU jacket options are specified for wipe-down compatibility rather than immersion, and the contact side needs to be dried before the head is re-seated. The exact agents, concentrations and wipe cycles the jacket withstands are on the confirmation list; if your protocol names specific disinfectants, send the list and we will match the material to it.

Documented Build and Clean Assembly

For medical and regulated programs, the cable is as much a documentation exercise as a component. We build to a documented, revision-controlled process with lot traceability on materials, and a clean-assembly option is available for assemblies that go straight into a clinical pack. Tell us what your quality system needs recorded and we will confirm in writing what can be supplied before you commit to a build. Note that we do not claim any third-party quality-system registration for this product line.

Electrical Protection and Options

Reverse polarity protection is included, because a magnetic interface that can be approached at an angle can also be approached wrongly. An IPX7 rated build is offered where the connector sits where it can be splashed, and the operating span quoted by comparable products runs from minus 20 to plus 85 C. Both the ingress rating and the temperature span are on the confirmation list.
