Tingfeng Hardware provides non-standard stamped spring contacts for encoder and sensor PCBs, manufactured from BeCu C17200 with force decay under 10% after 1 million rotation or sliding cycles, contact resistance ≤5mΩ, and tolerance of ±0.005mm. With 16 years of precision manufacturing experience, we understand that encoders and sensors demand long-term signal stability and maintenance-free operation — our spring contact solution directly serves this requirement and provides customized contact geometry design for different PCB layouts.

Product Overview

Spring contacts on encoder and sensor PCBs must maintain contact resistance without drift over millions or even tens of millions of movements, directly determining signal accuracy and system stability. Our BeCu C17200 contacts achieve precise geometry through precision stamping, stress relief heat treatment eliminates internal stress, and gold plating controls contact resistance below 5mΩ. For different PCB layouts and motion types (rotary or sliding), we provide non-standard customized spring geometry design. On the commercial side, clients increasingly focus on total cost of ownership — the value of a million-cycle contact lies in reducing downtime maintenance, extending calibration intervals, and ensuring continuous equipment operation.

Frequently Asked Questions
Can you handle complex custom designs and provide design optimization suggestions?

Absolutely. This is our core expertise. We provide free DFM analysis within 3–5 days, often helping clients achieve 15–30% cost reduction through design for manufacturability.

How do you ensure quality consistency and handle defect issues?

We implement a rigorous 4-stage QC system with 100% full inspection. Our track record shows a 99.99% qualification rate.

What are your lead times and how do you handle urgent orders?

Standard lead times: 3–7 days for prototypes, 7–15 days for mass production. We offer VIP prioritization cutting lead times by up to 30%.

Will I get timely responses and professional support throughout the project?

Yes. You get a 1v1 exclusive consultant with a 1-hour initial response commitment and 24-hour technical support.

Can you provide material certifications and environmental compliance reports?

Yes. We provide material certifications and environmental test reports (RoHS, REACH compliant) upon request.

How do you protect my designs and intellectual property?

We start with a mutual NDA and implement strict mold ownership protection and confidential data security measures.

What are your payment terms and MOQ requirements?

We offer flexible payment terms (T/T, L/C at sight) and MOQ from 1 piece for prototyping.
