industrial remote control features:
(1) High sensitivity, good accuracy, long effective distance and long signal persistence.
(2) The transmitter and receiver perform one-to-one encoding processing to make the anti-interference ability stronger.
(3) The appearance of the remote control is made of glass fiber reinforced nylon, which has strong resistance to acid and alkali corrosion, high and low temperature resistance, and waterproof and dustproof.
(4) Multi-button, up to 21 direction function buttons.
(5) Powerful voltage self-test function. When the transmitter voltage is less than 2.2V, the red light of the transmitter will flash slowly. When the voltage is less than 1.8V, the transmitter cannot work.
(6) Up/down can be set to normal, jump, and suppress each other.
