Project Description

Push button transmitter


Thanks to its small and flat design, the Planar-C fits in any breast pocket.
It is particularly suitable for controlling skip loaders, chippers, screening machines, conveyor belts, mobile transport systems, light poles, mixers, fog machines, high racks, suction/dishwashing vehicles, grinding machines and scrap presses.

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’.

3,6 V NBB battery system with charger

Ni-MH / 750 mAh
Operating time: approx. 40 hours with one battery charge

Illuminated buttons

Charging cradle for toggle switch transmitter with wall mounting

Practical charging cradle for fast charging. Can be mounted in buildings and vehicles.
(only in combination with AA battery, not possible with 3.6 V battery pack)

Carrying belt

Practical carrying belt for small hand-held transmitters.

Carrying bag

Practical carrying bag as protection against coarse dirt.


The Planar-C convinces with its small and compact design. Nevertheless, it offers space for up to 15 single-stage or 6 two-stage keys and can therefore be used in a variety of ways. A 7-segment LED display is also integrated in the Planar-C for visualization of the 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-C 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.



The teach-in function enables an optimized utilization of the joystick movement. By setting the min/max values on the transmitter side, the maximum move of the joystick is optimally utilized. As a result there are no longer any dead joystick motions. Even a minimum deflection of the joystick causes the immediate opening of a valve. [More info]

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

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

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]
