Data feedback

Customer-specific feedback information / status of the machine function

LBT frequency search

When switching on or switching to another frequency, the system checks whether the frequency channel used is occupied by other transmitters. If this is the case, the next frequency channel is checked until it is ensured that the transmitter can operate without interference. LBT is the abbreviation for ‘Listen before Talk’.

Carrying bag

Practical carrying bag bag as protection against coarse dirt.
(NBB-No.: 3.360.1010)


Thanks to its compact design and low weight, the Planar-B fits in any breast pocket or trouser pocket. By integrating up to 16 single-stage or 6 two-stage buttons, many functions can still be covered and the transmitter can be used in many different ways. A monochrome display is also integrated in the Planar-B for visualising machine feedback.
The replaceable AA cells used for the power enable maximum performance. Thanks to the charging contacts integrated in the transmitter, they can be charged quickly and easily in the appropriate charging cradle.
On request, you can also use the 3.6 V battery developed by NBB. This allows the transmitter to operate for up to 40 hours on a single charge.
Optionally, the Planar-B can be equipped with LBT (Listen before Talk) technology. This technology ensures that when the transmitter is switched on or when the frequency is changed, a check is made to see 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.


Multi-user system

The multi-user system enables radio communication between several transmitters and several receivers. Each transmitter can be optionally operated with several receivers at a workplace and / or vice versa. Provided that this connection is not otherwise used at this moment. [More info]

NBB battery system

NBB battery system

Nickel metal hydride batteries (NiMH) have a high energy density. The contacts have a self-cleaning design. The NBB battery pack is charged with a high charge current with a NBB charger. This quick charge is thermally controlled to optimize recharging and prevent overcharging. [More info]

LBT frequency search

LBT frequency search

When switching on or when switching the frequency, a check is carried out to determine whether the used frequency channel is reserved by another transmitter. If this is the case, the next frequency channel is checked until it is ensured that the transmitter can operate without disturbance. LBT is shortcut for Listen before Talk. [More info]
