Features of this industrial remote control:
(1) High sensitivity, good accuracy, long effective distance and long signal duration.
(2) Transmitter and receiver perform one-to-one encoding processing to make it stronger against interference.
(3) The exterior material of the remote control is made of glass fiber reinforced nylon, which has strong acid and alkali corrosion resistance, high and low temperature resistance, and waterproof and dustproof capabilities.
(4) Multiple buttons, up to 21 direction function buttons.
(5) Powerful voltage self-test function. When the voltage of the transmitter is less than 2.2V, the red light of the transmitter will flash slowly, and the transmitter cannot work when the voltage is less than 1.8V.
(6) Up/down can be set as normal, skip, and whether to inhibit each other.
