Characteristics of industrial remote control: (1) the sensitivity is high, the precision is good, the effective distance is far, the signal lasts for a long time. (2) the transmitter and receiver are processed by one - to - one coding to make them more robust. (3) the appearance of the remote controller is made of glass fiber reinforced nylon material, which has strong acid and alkali resistance, high and low temperature resistance and waterproof and dustproof ability. (4) with sharp stop mushroom head, plus 4 direction function keys. (5) strong voltage self-test function, when the transmitter voltage is less than 2.2V when the transmitter red light slow flashing prompt, when the voltage is less than 1.8V transmitter can not work. (6) on / off can be set to normal, toggle or inhibit each other.

Transmitter (handheld) You type: A4S-TX You: reinforced nylon shell * weight: about 290 grams Some protection grade: IP64 Frequency range: UHF to 430~440MHz To transmit power: less than 10dBm Some batteries: 2 alkaline battery 5 (AA) It security code: 32 (Group 4 billion 300 million not repeat identification code) To environment temperature: -35 degrees C ~ +80 ~ C (without considering the battery temperature) To control distance: 100 meters without interference
