altmann precision single-turn potentiometer DP113 series, original from Germany

altmann precision single-turn potentiometer DP113 series    original from Germany

altmann precision single-turn potentiometers consist of a resistive element and a rotating or sliding system, used to adjust voltage (including DC voltage and signal voltage) and current levels. The resistive element of an altmann potentiometer has two fixed terminals. By manually adjusting the shaft or slider, the position of the moving contact on the resistive element is changed, thereby altering the resistance between the moving contact and either fixed terminal, which in turn changes the voltage and current levels.

altmann single-turn potentiometer DP113 series specification description:

1). Precision wirewound potentiometer DP113 D2 Ze Hv KL  D2/D3, center-mounted M12x1, center-mounted precision potentiometer for use in factories and mechanical engineering. Even under unfavorable environmental conditions, the precious metal winding and multi-taper design ensure reliable operation. Thanks to ball bearings, the shaft can withstand axial loads of 5 kp during continuous operation. The potentiometer can rotate continuously, but a stop function can also be provided upon request. Optionally, it can be equipped with oil injection. To protect it from environmental influences, we offer versions installed in protective housings. Various adapter plates for mounting facilitate installation in the operating position. Shafts of special lengths can be manufactured individually.

2). Precision wirewound potentiometer DP113 Sy KL, synchronous flange 13, potentiometer for harsh industrial conditions. The precious metal winding provides maximum protection against environmental conditions. Multi-tap designs ensure safe functionality. Optional solder connections are available. Thanks to ball bearings, the shaft can withstand axial loads of 5 kp during continuous operation. The potentiometer can rotate continuously, but a stop function can also be provided upon request.

altmann Single-turn Potentiometer Precautions:

1). The resistive element of the potentiometer is mostly made of synthetic resin such as polycarbonate. Avoid contact with the following substances: ammonia water, other amines, alkaline aqueous solutions, aromatic hydrocarbons, ketones, ester hydrocarbons, and strong chemicals (with excessively high or low pH values), as these may affect its performance.

2). When soldering the terminals of the potentiometer, avoid using water-soluble flux, as this will promote metal oxidation and material mold growth; avoid using inferior flux, as poor soldering may cause difficulty in tinning, leading to poor contact or open circuits.

3). If the soldering temperature is too high or the duration is too long when soldering the terminals of the potentiometer, it may cause damage to the potentiometer. For pin-type terminals, soldering should be completed within 3 seconds at 235℃ ± 5℃, and the soldering point should be at least 1.5MM away from the potentiometer body; do not allow solder to flow through the circuit board during soldering. For wire-type terminals, soldering should be completed within 3 seconds at 350℃ ± 10℃. Additionally, avoid applying heavy pressure to the terminals, as this may easily cause poor contact.

4). During soldering, adjust the height of rosin (flux) entering the printed circuit board appropriately to avoid flux intrusion into the interior of the potentiometer, otherwise it will cause poor contact between the brush and the resistive element, resulting in INT and noise issues.

5). It is best to apply the potentiometer in a voltage adjustment structure, and the wiring method should preferably select the "1" pin for grounding; avoid using current adjustment structures, as the contact resistance between the resistor and the contact piece is unfavorable for the passage of large currents.

6). Avoid condensation or water droplets on the surface of the potentiometer, and avoid using it in humid places to prevent insulation deterioration or short circuits.

7). When installing "rotary" potentiometers, do not tighten the fixing nut too strongly to avoid damaging the threads or causing poor rotation; when installing "metal case linear slide" potentiometers, avoid using screws that are too long, otherwise they may hinder the movement of the sliding handle or even directly damage the potentiometer itself.

8). During the process of fitting the knob onto the potentiometer, the applied thrust must not be excessive (must not exceed the axial push-pull force parameters specified in the "Specification Sheet"), otherwise it may cause damage to the potentiometer.

9). The rotational operating force (rotation or sliding) of the potentiometer becomes lighter as the temperature rises and tighter as the temperature decreases. If the potentiometer is used in a low-temperature environment, please specify this so that specially formulated low-temperature resistant grease can be used.

10). In the design usage of the potentiometer shaft or sliding handle, the length should be as short as possible. Shorter shaft or sliding handle lengths provide better feel and stability. Conversely, longer lengths result in greater wobble and easier changes in feel.

11). The power rating of the potentiometer's carbon film can withstand an ambient temperature of 70℃; when the operating temperature exceeds 70℃, it may lose its functionality.
