4B's Encoder-Flex 1024 is an advanced rotary shaft encoder designed for monitoring various parameters, including slide gate position, shaft position, and shaft speed. Its applications range from tracking the position of rack and pinion gates, valves, and distributors to measuring the rotational speed of shafts, e.g. on slow-moving conveyors, mixers, and dryers. The Encoder-Flex 1024 employs cutting-edge technology to precisely monitor gate position or shaft speed. It offers customizable resolution, ranging from 1 to 1024 pulses per revolution, and provides multiple output options, including a 4-20 mA signal and quadrature pulsed output for directional speed. Additionally, it supports Modbus RTU communication for advanced configuration and diagnostics. To facilitate easy operation and target detection, the Encoder-Flex 1024 features two status LEDs. Calibration is easy, as the unit can be quickly adjusted using a magnet, whether you're measuring shaft speed, angular shaft position, or gate position. The device's durable sealed body is crafted from stainless steel for added longevity and reliability.
