Product Description:

The C9900-L100-0033 is a USB-powered accessory manufactured by Beckhoff and supplied within the C9 PC Accessories series. It is intended to connect directly to a PC-based controller so that TwinCAT runtime environments can identify licenses and store local data during machine operation. By occupying a single USB port, the module supports compact control cabinets where space efficiency and wiring simplicity are important.

The housing is slim, with a body thickness of 7.6 mm that allows close packing next to adjacent connectors. A body width of 15.5 mm leaves clearance for neighboring cables, and an overall length of 35.75 mm keeps the stick inside the panel outline. The cap adds 2.5 mm, raising the total external reach to 38.25 mm when installed. The USB plug itself extends 12.5 mm from the base and is 3.8 mm thick, providing a rigid fit that resists vibration common in automated equipment. Because the installation position is variable, the dongle can be oriented in horizontal or vertical receptacles without affecting performance. The IP20 protection class provides protection against finger contact and limits the device to cabinets where dripping water and dust are excluded.

The licensing features are provided in a Pre-Activated state, so only the functions required by the application are unlocked. Local data memory is present, allowing the controller to retain parameter sets directly on the stick. The accessory tolerates up to 95% relative humidity in non-condensing environments and operates on the TwinCAT 3.1 software platform. Controllers running build 4020 or higher recognize the device automatically. Electrical power is taken from the host through USB, eliminating separate wiring and ensuring that the module is energized only when the control PC is active.
