Indestructible Knob for FX51 Sensor

Tired of knobs breaking in your props?  Simple potentiometer-style knobs were not designed for the harsh world of escape rooms and need constant replacement.  We created the Indestructible Knob to solve this problem once and for all!  This knob will stand up to the worst abuse your players can dish out.  Built from a 1/2" steel shaft, an aluminum knob, and a 6/6 nylon engineered plastic housing, this thing is tough and can withstand hundreds of pounds of force.How it works: The knob assembly is mounted to a base plate supporting the knob shaft. The back of the shaft, the side inside the block, has a special magnet attached to it. That magnet is detected by our solid-state sensor modules, the FX51-SEN and FX52D.   Both have a 3D magnet sensor onboard and can be configured to trigger on any combination of knob rotation position.To connect the indestructible knob to a BAC, purchase FX51-SEN sensors, an FX45 Expansion Module (not included) and I2C JST-to-JST hookup cables (not included).
