FAQ

FAQ: How to Calculate Angles?

For a single-turn 4096-count encoder:

One full rotation of the encoder equals 360°, so each step represents 360° / 4096 ≈ 0.088°. If the difference between two encoder readings is 1000 steps, the corresponding angle difference is 360° / 4096 * 1000 ≈ 87.899°.

FAQ: How to Calculate Speed?
For a single-turn 2000-count encoder:

One full rotation of the encoder equals 360°, and it outputs 2000 pulses. If the encoder outputs 1000 pulses in 10 ms, the corresponding speed is calculated as 1000 / 2000 * 1000 * 60 / 10^3 ≈ 3000 RPM.

Additionally, we also support directly reading the encoder's speed value.

FAQ: How to Calculate Position for a Multi-Turn Encoder?
Assuming the encoder resolution is 12-bit multi-turn / 13-bit single-turn, and the encoder outputs a current position value of 16300:

The current number of turns is 16300 / 8192 = 19 (rounded down, using INT or TRUNC function in Excel).

The single-turn value is 16300 – 19 * 8192 = 7352.

FAQ:Where is your loading port?
Ningbo port, China.

FAQ: What is the delivery time?
The sample can be sent to customer within 5-10days.
In the off-season, goods are delivered within 15-30 days after receiving the deposit.
During the peak season, delivery is completed within 30–60 days after the deposit is received.

FAQ: Do you supply sample?
We can supply sample, but customer have to pay for the sample fee.
