HVR2

Vibration Immune UHF Narrow Band FM Multi-channel Receiver

Frequency:433.875 - 434.650MHz

The HVR2 receiver is the high vibration resistant version of the low cost RLC2H receiver. Its unique local oscillator design makes the unit almost immune to mechanical vibrations below 500Hz. This makes the HVR2 (with the matching TLC2H/LMT2 transmitter) to be used in mechanically troublesome areas such as crane and machine tool control, and remote operated vehicles
