From 433MHz to 868MHz

Tyro Remotes pushes back frontiers

Technically speaking this means that amongst other things the range of all Tyro wireless remotes has increased from 100 to 350 metres. Commercially speaking, we are pushing back frontiers with an entirely renewed website in 4 languages.

The new 868Mhz range is setting the bar
Fitting this familiar range with the latest digital technologies and transmitting on the 868Mhz band offers you the following advantages: 
 
- stable range of 350 metres; less risk of interference;
- additional protection thanks to the internal fuse;
- programmable inputs and outputs;
- suitable for PWM;
- active emergency stop (EN 954-1 / ISO 13849-1);
- waterproof receiver (IP 68).

And of course, ‘the specialist in the area of compact hand-helds' still stands for:

- Guaranteed safety (E11 Automotive/2006/96/EC-R&TTE/EMC).
- EMC-e11 tested for use on the public highway.
- Flexibility of product and service.

The radio modules in the transmitter and the receiver have been replaced by chip technology 
This increases the range to not less than 350 metres. Not only that, the radio module is now completely digital instead of analog and as a result of this it gets far less affected by the external sources of interference. Just like the 433 MHz frequency, 868 MHz has been also released for use. However, the use of the 868 MHz frequency is regulated with many strict regulations. As a result, the 868 MHz frequency is used far less and is almost exclusively used by professional providers.

Brief summary of the advantages:

  1. Enormous range of 350 metres in normal conditions.
  2. Far more stable range in contrast to analog systems as the transmitter and reciever are always on one frequency.
  3. Also, gets less affected by external influences such as mist, damp, metal or radiation from other devices.
  4. Need not to press again if the signal falls away temporarily.
  5. This is because the digital transmitter sends short messages in pulses. As a result, two systems can work trouble-free on the same frequency.
  6. In the previous systems, only the strongest signal could reache the receiver.
  7. Additional option: If a different frequency is still preferred, then the 868 MHz systems can be programmed such as 868, 1-868, 2-868,3 etc.
  8. Additional option: Programmable outputs (PWM, timer, flip/flop (latching)).
  9. Additional option: Combinations of keys possible.
  10. Additional option: Many more hand-held transmitters can now be programmed on one receiver. 54 instead of 7!
  11. Additional option: Category 3 active emergency stop is possible. To conform to the highest safety categories in the Machinery Directive, it is possible to incorporate a so-called active emergency stop. When the hand-held transmitter is switched on, an emergency-stop relay will become active. When the emergency stop button is pressed, this relay will de-energize. It will not become active again until you press the ‘on’ button once more.

The additional options must be programmed in advance and are available in consultation with an extra price.

Recognition  

The appearance of the systems differs as follows:

- Shorter antenna: the 433 = 17 cm long, the 868 = 8.5 cm long.
- Receiver: Status led on the 433 it lights up red, on the 868 it lights up yellow.
- Hand-held transmitter: when the 868 hand-held transmitter is switched on with the on button, the led flashes. On the 433 version this is not the case.
- The serial numbers and model descriptions on the stickers are different. The model description for the 868 versions always contains RX 4041(on the receiver) or TX 4041(on the transmitter).

The manuals and product sheets for both systems can be found on the website under downloads.
