PTC-10 Cermet Potentiometers Amphenol Piher PTC-10 Cermet Potentiometers feature 235° ±5° mechanical rotation angle and 220° ±20° electrical rotation angle. These devices are designed with a cermet resistive element and plastic material that complies with UL 94V-0 flammability standards. These potentiometers incorporate three wiper positions for operation, including initial, 50%, and fully clockwise. Amphenol Piher PTC-10 Cermet Potentiometers offer alumina substrate and IP54 protection according to IEC 60529. The series is available in vertical mounting with horizontal adjustment and horizontal mounting with vertical adjustment. Options include without a shaft, with a thumbwheel, and with shaft packaging styles in different units. The PTC-10 cermet potentiometers operate in a standard temperature range of -40°C to +90°C.
