Multiturn Hybrid Potentiometer HH17/19

Very precise, durable and economical multiturn potentiometer for a wide range of applications

The HH17/19 series was developed for applications that require a very precise, durable and economical multiturn potentiometer. With a compact Ø22 mm housing and a wide range of options, this potentiometer is ideal for industrial controls, measuring systems and other applications where accuracy and reliability are important.

The potentiometers have a wirewound resistive element that is coated with a conductive plastic layer. This eliminates the so-called winding jumps and the resolution is almost infinite. The smooth surface of the resistor element gives the hybrid potentiometer a significantly longer service life, making it suitable for use as a position feedback device in bearing control loops.

The potentiometers HH17 with shaft Ø6.35 mm and HH19 with shaft Ø6.00 mm are equipped with a screwdriver slot to facilitate zero point adjustment. In addition, an optional built-in slipping clutch protects the potentiometer from damage caused by movement beyond the end stops. The potentiometer is available with 3, 5 or 10 turns. The radial, gold-plated connection pins are suitable for spade connectors (2.8 mm to DIN 46247 Part 3), and the plug-in version simplifies electrical installation.

Options:

• Multiturn: Available in 3, 5 and 10 turns
• Slipping clutch: Protection against over-tightening of the end stops
• Plug-in version: Simplified electrical installation
• Tandem version: For redundant signal output, up to 10 gangs
• Increased torque: Available on request
• Resistance values: 1 kOhm to 100 kOhm
• Linearity: ±0.25 % (option up to ±0.1 %)
• Resistance tolerance: ±10 % (option: ±5 %)
• Sealing: Shaft sealing (IP65)
• Shaft adaptations: Various geometries and lengths available
• Center tap: Enables voltage or current tapping at a defined point on the resistor track and extends the functionality, this enables the additional output of measurements
