Vishay Intertechnology 138-0-0-103 Potentiometer

The Vishay Spectrol 138-0-0-103 Rotary Potentiometer delivers precise, manual setpoint adjustment for industrial control and signal conditioning. This 10 kΩ linear-taper device from the 138 series combines a 2 W power rating with a 1-turn rotary shaft and a conductive plastic resistive element, making it well suited for stable, repeatable resistance changes in control loops. It is designed for Bushing / Panel Mount installation with an industrial sealed construction, and operates across -55°C to +125°C with a temperature coefficient up to ±500 ppm/°C. The potentiometer provides an analog variable resistance output and carries a 166 V voltage rating, supporting demanding environments and reliable performance over up to 2 million shaft revolutions. Commonly installed in control panels, instrumentation, test benches, automation machinery, and process control systems where manual adjustment or position feedback is required, it serves application roles in industrial automation, instrumentation, process control, and machine control. Typical use cases include operator control stations, testing equipment, calibration systems, and OEM equipment requiring a stable, repeatable resistance adjustment. Verified compatibility and alternatives include Vishay replacements 138-0-0-102, 138-0-0-202, and 138-0-0-502 for similar specifications and form factors.
