Trimmer potentiometers are resistors which, when adjusted manually, can be set to any value of resistance from a maximum to almost zero, depending upon the specific trimmer type. The RJ12FY202 is a two-turn trimmer potentiometer, and part of the RJ series of trimmers manufactured by CTS Corporation. This series of trimmer potentiometers is known for its higher accuracy, low noise and long-term reliability.

The RJ12FY202 is designed for use at various temperatures, ranging from - 45 to + 160°C, and provides very high accuracy over the entire 1 ¼ turn of the shaft, within ± 10%. It is manufactured in a long life design, and has a limited life of 1,000,000 cycles. The RJ12FY202 is ideal for use in a wide range of applications, including medical equipment, instrumentation, and audio systems.

The RJ12FY202’s construction features a terminal board with wrap-around terminals. An adjustable rubber cup is provided for extra protection, from which the shaft protrudes. The RJ12FY202 also has a 2-pin mounting feature, which allows it to be securely attached to a variety of materials. This allows the trimmer to be securely mounted for easier adjustment.

The RJ12FY202 operates on the principle of a variable resistor, in which resistance is changed by altering the position of a wiper, or sliding contact, on the track it trips along. The RJ12FY202, as a two-turn trimmer, has two tracks in an arc pattern, and two wipers, enabling it to cover an entire 1 ¼ turn of its shaft. This produces a fine adjustment for finer accuracy than the single track and single wiper designs followed in other trimmer models.

The RJ12FY202 is available in a range of resistive values, from 10 to 100kΩ, and in pack sizes of either 5 or 10. The wiper tracks have been designed to provide a smooth adjustment path, with excellent linearity and repeatability over a wide range of temperatures, allowing for precise adjustment to the desired value.

In summary, the RJ12FY202 is a two-turn trimmer potentiometer, designed for higher accuracy, long life and reliable performance. It is suitable for use in a wide range of applications, including medical equipment, instrumentation and audio systems. The two-turn design offers superior accuracy, with two wipers enabling it to cover an entire 1 ¼ turn of its shaft for finer adjustments. It is available in a range of resistive values, and in pack sizes of either 5 or 10. The RJ12FY202 is an ideal choice for those seeking superior accuracy and reliable performance from their trimmer potentiometer.
