Precautions
Use of Chemicals: Avoid contact with ammonia, amines, alkali solutions, aromatic hydrocarbons, ketones, esters, and halogenated hydrocarbons as polycarbonate resins are used.
Use of Flux: Avoid water-soluble flux to prevent adverse effects on materials.
Soldering: Prevent solder from flowing onto the upper surface of the PCB to avoid imperfect contacts.
Recommended Circuit Configuration: Recommended for voltage adjustment. If used for current adjustment, confirm performance under actual operating conditions due to potential influence from contact resistance.
Residual Resistance: Standard products have a sulfurization-resistant film over silver electrodes. Contact for low residual resistance requirements.
Dew Condensation: Avoid use in conditions where dew or water drops may occur to prevent reduced insulation or short circuits.
Low Temperature Operation: Customization for smoother rotary movement is available for low-temperature environments. Specify when ordering.
