P502 Small angle rotary sensor
Compact rotary sensor with high-resolution angle feedback for hydraulic and pneumatic cylinders. Ideal for industrial machinery where precision at small deflection angles is critical.
Key features
- Factory-calibrated angle range from 5° to 15°
- Non-contacting inductive technology for long life
- Sealing to IP65 or IP67 depending on configuration
- Infinite resolution and excellent linearity (≤ ±0.25% FSO)
- Robust stainless steel shaft and anodised aluminium housing
- Wide operating temperature range: -40 °C to +125 °C
Performance highlights P502 Small angle rotary sensor
The P502 delivers high-resolution angle feedback in the smallest angular ranges. With its non-contacting inductive technology, it ensures superior reliability and no mechanical wear—ideal for repetitive motion or demanding environments. It achieves infinite resolution with ≤ ±0.25% FSO linearity and operates reliably even under vibration or shock.
Usage conditions
This rotary sensor is optimized for industrial and OEM integration. It can be calibrated to any angle between ±2.5° and ±7.5°, and it remains highly stable across its full operational temperature range of -40 °C to +125 °C (buffered: -20 °C to +85 °C). The IP65/IP67 sealing options protect against dust and moisture in tough environments.
Possible applications
- Hydraulic and pneumatic cylinder positioning
- Industrial automation feedback systems
- OEM machinery integration
- Scientific instrumentation
- Robotics and motion systems
Advantages of choosing the P502
With its small size, robust housing, and flexible mounting options (flange or servo), the P502 sensor is a go-to solution for engineers who demand accuracy without compromising durability. It eliminates the need for bulky LVDT coils and offers simplified installation with a factory-set calibration and optional spring return.
Other important features
- Output options: voltage (±5V, ±10V), current (4–20mA), ratiometric, etc.
- EMC compliant: EN 61000-6-2, EN 61000-6-3
- Vibration and shock resistant (10 g & 40 g respectively)
- Custom connector and cable options
- MTBF: 350,000 hrs at 40 °C
