• 100-ohm resistance value
• Spindle drive with reduction gearing for precise adjustment
• Multi-turn curve driver
• Front-panel mounting with plastic knob

Product description

This precision rotary potentiometer is designed for accurate resistance adjustment in measurement and control circuits. The multi-turn spindle with mechanical reduction gearing enables extremely fine adjustments across a range that requires several rotations. This eliminates the coarse jumps that input potentiometers exhibit when being adjusted.

The 100-ohm resistance value is suitable for measurement branches, voltage dividers, and control loops in the low-resistance range. Anyone performing highly precise adjustment tasks in measuring instruments or laboratory power supplies saves time thanks to its immediate readiness for use without additional interfacing.

In everyday projects, the module is used when voltages or currents need to be adjusted with accuracy in the low percentage range, for example when calibrating analog multimeters or adjusting amplifier stages. The reduction gearing ensures adjustment increments in the milliohm range.

An enclosure with the appropriate hole pattern for the spindle is required for installation. The connection pins require a soldered connection or socket. A wiper compensator for wear is not provided, so despite the precision design, readjustment may be advisable after long periods of operation.

Safety information

This precision potentiometer is intended exclusively for building prototypes and for testing and development purposes. It must not be installed in household mains circuits. Work on or near electrical installations requires a qualified electrician; if anything is unclear, please consult a qualified electrician before commissioning.
