SOP SOPN-200 Dynamic Rotary Torque Sensor, 5N·m, 0~10V & RS485 Output, 24VDC, 8000RPM

The included 3-meter cable typically provides connections for 24V DC power, ground, the 0-10V analog output, and the RS485 data lines (A+/B-). For precise pinout configuration and Modbus register mapping, consult the official SOPN-200 datasheet. Always ensure proper shielding and termination for the RS485 communication line.

Calibration, zeroing (tare), and digital filter adjustment are performed via commands sent over the RS485 Modbus interface using dedicated register addresses. The integrated OLED display will show confirmation of these changes. The sensor should be zeroed under a no-load, stationary condition for optimal accuracy.

Yes, the SOPN-200 is a bidirectional dynamic torque sensor. It provides signed torque values, distinguishing between clockwise and counter-clockwise rotation. The 0-10V output can be configured for a unipolar or bipolar range (e.g., 0-10V for 0 to +5 Nm, or 0-5V for -5 Nm and 5-10V for +5 Nm), while the RS485 output provides the signed digital value directly.

The sensor is rated for a maximum rotational speed of 8000 RPM. Within this range, accuracy specifications (0.1% linearity, 0.05% repeatability) are maintained. Exceeding this speed may cause mechanical stress, affect bearing life, and degrade signal integrity. High-speed applications benefit from the sensor's 1 kHz response frequency.

The sensor is designed for inline installation. The central shaft rotates with the motor and load via couplings, while the outer housing remains stationary. The torque is measured across the rotating shaft via a non-contact method (e.g., rotary transformer or wireless telemetry) that transmits the signal to the stationary electronics in the housing.
