Rotary position sensor

Type DST X520

For mobile hydraulic applications

The Danfoss DST X520 rotary position sensors without shaft are designed for use in mobile hydraulic applications.

Danfoss DST X520 series uses contactless Hall technology with measurement ranges up to 360°. The Sensors designed for o•-highway applications and resistant to shock and vibrations and with high electromagnetic compatibility.

They are E1 approved for on-highway applications. They comes with either analogue, CANopen or SAE J1939 output.

Single and redundant sensor types are available, making the complete portfolio suitable for safetycritical applications.

Features

• Contactless Hall technology for almost inƒnite sensor life time

• Single or Redundant ranges up to 360° (±180°)

• Output: Analogue, CANopen or SAE J1939

• Linearity: < ± 0.5% FS

• Resolution:

◦ 12 bit (analog)

◦ 14 bit (CANopen/SAE J1939)

• IP protection level IP67 - IP69K with female mating connector

• High quality 10 mm SmCo Magnet
