Features: brand new and high quality Made of ABS and metal, which is durable and reliable. The 8CH controller adopts the ASK communication mode controller, which has the characteristics of strong data transmission stability and high receiving sensitivity. And the data transmission rate is high, free from motor interference. The output power of the product is large, and the eight-button remote control can be used in conjunction with the industrial control eight-way, which can be applied to the control scene of industrial high-power products. The program adopts rolling code encryption processing, which has strong confidentiality and more reliable security performance. Using brand single-chip microcomputer independent programming, with SCT2260 encoding format, SCT2260 encoding chip, can have up to 59049 address codes, which makes the repetition rate very low and has higher security.
