Product catalog summary

Overview: The document details the specifications and features of the PRHY12 analog displacement sensor designed for integration into hydraulic cylinders. It highlights the sensor's suitability for small cylinder rods and its optimal performance across various oil viscosity conditions.

Features:

Utilizes conductive plastic potentiometer technology with infinite resolution.
Equipped with a precious metal multi-contact wiper and a light alloy profiled support.
Available with wire or connector outputs.

Electrical Specifications:

Theoretical electrical travel ranges from 100 mm to 1000 mm.
Standard independent linearity is ± 0.1%, with an optional ± 0.05%.
Total resistance is 425 Ω/cm, with options from 350 Ω/cm to 4000 Ω/cm.
Temperature coefficient is -300 ± 300 ppm/°C.
Power rating is 0.3 W/cm at +25 °C, dropping to 0 W/cm at +125 °C.
Wiper current is ≤ 1 mA, with recommended load impedance ≥ 1000 Rn.
Dielectric strength is 1000 VRMS, 50 Hz, for 1 minute.
Insulation resistance is ≥ 10 GΩ at 500 VCC.
Output smoothness is ≤ 0.05%.

Mechanical Specifications:

Mechanical travel is TET + 1.5 mm.
Driving force is ≤ 1 N typical, with backlash < 10 μm.
Maximum displacement speed is 1.5 m/s in 32 cst oil.

Performance:

Operating temperature range is -40 °C to +125 °C.
