6. FAQ (Frequently Asked Questions)
No. | Question | Summary Answer |
---|---|---|
1 | How to select an encoder? | First, determine whether you need an incremental or an absolute encoder; if in doubt, contact the sales/service department. |
2 | What specifications are required before ordering? | Encoder type (solid shaft or hollow shaft), external diameter (min. 25mm, max. 100mm), shaft diameter (min. 4mm, max. 45mm), phase & resolution (min. 20 ppr, max. 65536 ppr), output mode (e.g., NPN, PNP, voltage, push-pull, line driver, etc.), and supply voltage (DC5V-30V). |
3 | How to choose the right encoder by yourself? | Verify the detailed specification description, check installation dimensions, and contact the supplier for more details. |
4 | What is the minimum order quantity? | The MOQ is 20 pieces; lower quantities are possible but may incur higher freight costs. |
5 | Why choose the “Gertech” brand encoder? | The encoder is designed and developed by our engineering team since 2004, with most components imported; manufactured in an anti-static, dust-free workshop, and ISO9001 certified. |
6 | What is the lead time? | 3 days for samples; 7–10 days for mass production. |
7 | What is the warranty policy? | 1-year warranty and lifetime technical support. |
8 | What are the benefits of becoming an agent? | Special pricing, market protection, and full support. |
9 | How to become a Gertech agent? | Send an inquiry; we will contact you as soon as possible. |
10 | What is the production capacity? | 5000 pieces per week; a second-phase production line is currently under construction. |
7. Installation and Precautions
No. | Instruction |
---|---|
1 | Use an elastic soft coupling between the encoder shaft and the user’s output shaft to avoid damage due to misalignment or runout. |
2 | Pay attention to the allowable axial load during installation. |
3 | Ensure that the axial difference between the encoder shaft and the user’s output shaft does not exceed 0.20 mm, and the angular deviation is less than 1.5°. |
4 | Avoid impact, knocking, or dropping during installation. |
5 | Do not reverse the power line and the ground wire. |
6 | The GND (ground) wire should be as thick as possible (generally larger than φ3). |
7 | Output wires should not overlap with each other to prevent damage to the output circuit. |
8 | The signal wires should not be connected directly to a DC power supply or AC current to avoid damaging the output circuit. |
9 | Motors and other equipment connected to the encoder should be properly grounded to prevent static electricity. |
10 | Use shielded cables for wiring. |
11 | Check all wiring thoroughly before starting the machine. |
12 | For long-distance transmission, consider the signal attenuation factor and choose an output mode with low impedance and strong anti-interference capability. |
13 | Avoid using the encoder in strong electromagnetic interference environments. |
