Nemicon OVW2 OVW2-25-2MD incremental rotary encoders

Nemicon OVW2-25-2MD is an incremental rotary encoder in the OVW2 series. Here is a detailed introduction:

Technical Specifications

Resolution: It has a resolution of 2500 pulses per revolution, which can accurately measure the rotation angle and speed of the shaft.

Power Supply Voltage: The required power supply voltage is DC 4.75 - 5.25V, and a 5V DC power supply is available.

Output Method and Signal: It adopts line - drive output (differential output), and the output signals include A - phase, B - phase, Z - phase, - A - phase, - B - phase, and - Z - phase. The origin output logic is positive logic (high - level effective). The highest response frequency is 200KHz, and the output waveform is a square wave. The duty cycle is 50 ± 25%, the phase difference is 1/4T, and the origin signal width is 1T. The rise / fall time is 200ns.

Mechanical Parameters: The maximum allowable rotational speed is 6000r/min. The starting torque is 6.8×10⁻³ - 2.9×10⁻² N·m, and the shaft moment of inertia is 8×10⁻⁷ kg·m². The allowable axial load on the shaft is 19.6N, and the allowable radial load on the shaft is 29.4N. It has a solid shaft with a diameter of φ6mm, an outer diameter of φ38mm, a pitch circle diameter (PCD) of φ28mm, and is fixed with 3×M3 screws to a depth of 5mm.

Environmental Conditions: The operating environment humidity is 35 - 85% RH (no condensation), and it can withstand an impact of 490m/s² for 11ms in each of the three axial directions and vibrations of 10 - 50Hz with an amplitude of 1.5mm for 2h. The protection level is IP50. The operating environment temperature is - 10 °C to + 70 °C, and the storage environment temperature is - 30 °C to + 80 °C.
