The Planar-D convinces with its small and compact design and can be used in a variety of applications. With up to 9 single-stage buttons and an extremely flat design in breast pocket format, this is the smallest transmitter in the NBB product portfolio. Exchangeable AA cells allow maximum flexibility. The Planar-D is inherently equipped with charging contacts that allow rechargeable batteries to be charged using a charging cradle.Optionally, the 3.6 V battery developed by NBB itself can also be used as an energy source. With only one charge, it can power the transmitter for up to 40 hours.
The feedback from your machine can be visualised on the integrated 7-segment display. The Planar-D can also be expanded with LBT technology. LBT stands for Listen before Talk and means that when the transmitter is switched on or when the frequency is changed, the system checks whether the selected frequency channel is already occupied by other transmitters. If this is the case, the next channel is checked until it is ensured that the channel is free and the transmitter can operate without interference.
