AXI-Link Charging Connector
This is the 3-pin industrial charging input used on the ST100 and ST200 transmitters. The same connector is found on the 2- and 4-channel variants of the ST100 and the 2-, 4- and 6-channel variants of the ST200. With its thicker pins and more robust body compared with consumer-type micro connections, it is intended for dusty and vibrating use in a workshop environment.
The charging connector is the most frequently used mechanical part of a rechargeable transmitter: it is plugged in at the end of every shift and unplugged at the start of every shift. For this reason the connector type is not an electrical detail but a choice that determines service life.
What AXI-Link means in practice:
- 3-pin industrial construction: because the pins are thick, they fatigue less than micro connectors under repeated plugging and unplugging.
- Tolerance to orientation mistakes: on industrial connectors the mating orientation is fixed; forcing it in the wrong way round is less likely.
- Maintenance point: oxidation or dirt build-up on the pins increases contact resistance. The symptom is the remote control not charging even though it is plugged into the charger.
Do not use a wire brush when cleaning the connector; it scratches the contact surface and makes matters worse. Wiping with a dry, clean cloth and, if needed, using a suitable contact cleaner is enough.
The battery capacity, charging time and the charger's output ratings are not stated in the product data; for this information see the technical specifications on the product page and the user manual. Since the LF200 remote control of the SF series runs on batteries, it does not include this connector.
