1SFA611410R1006 ABB MT-100B Potentiometer Knob

Why Choose the ABB MT-100B Potentiometer Knob?

The ABB MT-100B, supplied under ABB order code 1SFA611410R1006, is a potentiometer knob operator designed for industrial control panels, machinery and automation equipment. It provides a practical rotary interface for operating a compatible panel-mounted potentiometer where continuously adjustable manual control is required.

The MT-100B features a black knob with an integrated position indicator and white marking, allowing the selected setting to be identified easily from the front of the control panel. It is designed for potentiometer shafts with a diameter of approximately 6–6.35 mm and a minimum shaft length of 20 mm.

This version is supplied as a knob without a resistor and features a black plastic bezel. It therefore provides the mechanical operator interface while allowing the appropriate potentiometer or resistance element to be selected separately for the electrical requirements of the application.

Key Advantages

• Rotary potentiometer knob for continuously adjustable industrial controls.
• Integrated position indicator provides clear visual reference of the selected setting.
• White marking improves visibility of the knob position.
• Designed for 6–6.35 mm potentiometer shafts.
• Suitable for shafts with a minimum length of 20 mm.
• Black plastic bezel suits ABB modular pilot-device installations.
• Supplied without a resistor, allowing the potentiometer element to be selected for the application.

Precise Manual Adjustment for Industrial Controls

Potentiometer knobs provide an intuitive rotary interface for applications requiring variable manual adjustment rather than simple on/off or discrete-position switching. Typical functions include adjusting speed references, process setpoints and other analogue control values when used with a suitable potentiometer and control circuit.

The ABB MT-100B provides the front-panel operating knob without a fixed resistance element, giving panel designers flexibility to select the potentiometer characteristics required by the application. Its integrated position indicator and white marking also provide a clear visual reference for repeatable manual adjustment.

Typical Applications

• Industrial machinery control panels.
• Variable speed reference controls.
• Analogue process setpoint adjustment.
• Automation and production equipment.
• Motor and drive control panels.
• OEM machinery and operator stations.
• Manual adjustment of compatible potentiometers.
