The TW11BLK12 is a single-axis Hall effect thumbwheel controller designed for proportional control applications. It utilizes non-contacting Hall effect technology to deliver a ratiometric analog output from 0V to 5V over an 80-degree mechanical travel range. This specific model is configured with a black actuator, standard spring tension for self-centering, and is terminated with 41cm 22AWG PTFE wires. Engineered for high-reliability use, it has an expected life of 5 million cycles and features electronics sealed to IP67 standards. The combination of precise control and robust construction makes it ideal for industrial panels, material handling equipment, and other human-machine interfaces.
