AMPHENOL PIHER

Potentiometers and position, angle, speed and current sensors

About the manufacturer

Piher Sensing Systems is a Spanish manufacturer of position-sensing and control solutions with a history dating back to 1950. The company began as a specialist in electronic components and potentiometers and later expanded into contactless sensing technologies designed for demanding environments.

Today, Piher, an Amphenol company, develops standard and configurable position, angle, speed, tilt and current sensors. Its portfolio includes PCB and panel potentiometers, resistive position sensors, contactless Hall-effect sensors, speed and direction sensors, inclinometers and current transducers.

The company focuses on compact, mechanically robust solutions with stable electrical performance. Custom engineering is also an important part of Piher’s business, allowing electrical and mechanical designs to be adapted to the requirements of a specific device or operating environment.

Applications

Piher components are used both as adjustment elements and as feedback devices for position, angle or current in control systems. Typical application areas include:

• Industrial automation – adjustment, positioning and feedback in machinery.
• Automotive electronics – sensing the position of moving mechanisms, pedals, throttles and auxiliary systems.
• Off-road vehicles and working machinery – sensors designed for vibration, contamination and changing environmental conditions.
• Robotics and AGV/AMR systems – angle and position feedback for lifts, grippers and steering mechanisms.
• Energy and renewables – angle sensing in solar tracking and actuator systems.
• Consumer electronics and instrumentation – potentiometers for adjustment and calibration.

AMPHENOL PIHER products available from Maritex

The AMPHENOL PIHER range available from Maritex focuses primarily on potentiometers used for adjustment and calibration in electronic circuits. The portfolio includes popular PT10 PCB trimmer potentiometers.

Available product groups include:

• Through-hole trimmer potentiometers.
• PT10-series potentiometers.
• Versions with different resistance values.
• Horizontal and other mounting variants depending on the series.
• Components for calibration and adjustment of electronic circuits.

One example is the PT10LV-250K ROHS, a horizontal PT10 trimmer with a resistance of 250 kΩ. When selecting a potentiometer, key parameters include resistance value, resistive track material, tolerance, mounting method and component orientation on the PCB.
