The Q400 and Q404 are compact, four-button industrial wireless remote controllers designed for winches, mini electric hoists, rail cranes, trolley lifting systems, and small workshop lifting equipment. Both models use the same housing, receiver system, and wireless control capabilities. The Q400 is suitable for single-speed directional control, while the Q404 supports dual-speed button operation, making it suitable for applications requiring more flexible lifting control.
With a Semtech LLCC68 low-power wireless chip, hardware frequency hopping and carrier sensing, the Q Series helps improve signal stability, reduce interference and lower overall power consumption. The ergonomic transmitter and silicone anti-drop cover make it more durable and comfortable for industrial operation.
