Why Choose the ABB MT-300B Potentiometer Knob?
The ABB MT-300B is a potentiometer operating knob without resistor designed for industrial control panels, machinery and automation systems. Part of the ABB Modular pilot device range, it provides a convenient rotary operator for externally mounted potentiometers where the resistance element is supplied separately.
The MT-300B features a black knob with integrated position indication and white marking, providing operators with a clear visual reference for the selected setting. Its durable chrome-metal bezel gives the operator a robust industrial finish suitable for machine control panels and operator stations.
Designed for the ABB 22 mm modular pilot device system, the MT-300B accommodates potentiometer shafts with a diameter of 6–6.35 mm and requires a minimum shaft length of 20 mm. It contains no resistor, allowing the external potentiometer element to be selected according to the application. ABB identifies this exact product under order code 1SFA611410R3006.

Flexible Rotary Adjustment for Industrial Control Systems
Potentiometer operators provide a convenient manual interface for adjusting analogue setpoints such as speed, level, temperature or process references. Because the ABB MT-300B contains no resistor, it can be mechanically coupled to a suitable external potentiometer selected to provide the resistance and electrical characteristics required by the control circuit.
The integrated position indicator allows operators to identify the approximate rotary setting at a glance. Combined with its standard 22 mm modular format and chrome-metal bezel, the MT-300B is well suited to industrial control panels where a robust and consistent operator interface is required.
Typical Applications
- Industrial machinery control panels.
- Analogue setpoint adjustment.
- Motor speed reference controls.
- Process parameter adjustment.
- Operator stations and control desks.
- Industrial automation and OEM machinery.
