HVR2
UHF Narrow Band FM Vibration Resistant Multi Channel Receiver
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 TLC2H-433-5 transmitter)
to be used in mechanically troublesome areas
such as crane and machine tool control, and
remote operated vehicles.
