描述

The 67XR1K is a Model 67 cermet trimming potentiometer designed for applications requiring adjustability and calibration in medical and consumer electronics. It features a 3/8" square multiturn design with 20 turns of electrical travel and is sealed to be compatible with aqueous PCB cleaning processes. The potentiometer offers a standard resistance range from 10 Ohms to 2 Megohms with ±10% tolerance (±20% for values below 100 Ohms), an input voltage rating of 200 Vdc maximum, and a power rating of 0.5 Watts at 85°C. With dielectric strength of 900 Vrms, insulation resistance of 1,000 Megohms minimum, and essentially infinite resolution, this component provides highly reliable performance across an operating temperature range of -55°C to +125°C. Its clutch-action mechanical stops, low starting torque of 5 oz.-in. (0.035 N-m), and lightweight design (1.1 grams) make it ideal for precision calibration and adjustment applications in demanding environments.
