6. FAQ (Frequently Asked Questions)

No.QuestionSummary Answer
1How to select an encoder?First, determine whether you need an incremental or an absolute encoder; if in doubt, contact the sales/service department.
2What 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).
3How to choose the right encoder by yourself?Verify the detailed specification description, check installation dimensions, and contact the supplier for more details.
4What is the minimum order quantity?The MOQ is 20 pieces; lower quantities are possible but may incur higher freight costs.
5Why 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.
6What is the lead time?3 days for samples; 7–10 days for mass production.
7What is the warranty policy?1-year warranty and lifetime technical support.
8What are the benefits of becoming an agent?Special pricing, market protection, and full support.
9How to become a Gertech agent?Send an inquiry; we will contact you as soon as possible.
10What is the production capacity?5000 pieces per week; a second-phase production line is currently under construction.

7. Installation and Precautions

No.Instruction
1Use an elastic soft coupling between the encoder shaft and the user’s output shaft to avoid damage due to misalignment or runout.
2Pay attention to the allowable axial load during installation.
3Ensure 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°.
4Avoid impact, knocking, or dropping during installation.
5Do not reverse the power line and the ground wire.
6The GND (ground) wire should be as thick as possible (generally larger than φ3).
7Output wires should not overlap with each other to prevent damage to the output circuit.
8The signal wires should not be connected directly to a DC power supply or AC current to avoid damaging the output circuit.
9Motors and other equipment connected to the encoder should be properly grounded to prevent static electricity.
10Use shielded cables for wiring.
11Check all wiring thoroughly before starting the machine.
12For long-distance transmission, consider the signal attenuation factor and choose an output mode with low impedance and strong anti-interference capability.
13Avoid using the encoder in strong electromagnetic interference environments.
