HVR2
|
|
The HVR2 receiver is the high vibration resistant
version of the low cost RLC2 receiver. Its unique local oscillator
design makes the unit almost immune to mechanical vibrations below
500Hz. This makes the HVR2 (with the matching TLC2 transmitter)
to be used in mechanically troublesome areas such as crane and machine
tool control, and remote operated vehicles.
