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 belt

Practical carrying belt for small hand-held transmitters.

Carrying bag

Practical carrying bag as protection against coarse dirt.


The explosion-proof safety radio remote control Planar-B1 EX can be used in areas with gas explosion hazards in zones 1 and 2. This makes it the perfect transmitter for offshore applications and for example on oil platforms.

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 visualizing machine feedback.

The key transmitter is powered by the 3.6V 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.



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]

Data reporting

Visual representation of Operating Range, Transmission signal strength, Status of the machine function and Customer-specific information as well as logos supplemented by acoustic feedback (buzzer can be activated). [More info]


If transmitters are to be used in potentially explosive environments, appropriate technical precautions must be taken. The Planar-B1 and -B2 EX transmitters have been specially developed and certified for such applications. [More info]
