RoHS-compliant terminal materials are essential for manufacturers exporting electrical and electronic products to global markets, especially the EU. 그만큼 유해물질 제한 (RoHS 규제) directive limits the use of specific toxic materials in electrical components—including terminals, 커넥터, and wire harness parts.
엔지니어용, sourcing managers, and OEMs, understanding which materials are compliant—and how to verify them—is critical to avoiding regulatory risks, product rejection, and supply chain disruptions.

빠른 답변: What Are RoHS-Compliant Terminal Materials?
RoHS-compliant terminal materials are metals and surface finishes that meet the EU RoHS directive by restricting hazardous substances such as lead (납), 카드뮴 (CD), 수은 (수은), and hexavalent chromium (Cr6+).
Common RoHS-Compliant Materials for Terminals
구리 (pure or alloyed)
Lead-free brass
인청동
스테인레스 스틸 (in specific applications)
Common RoHS-Compliant Platings
주석 (Sn) 도금
니켈 (~ 안에) 도금
금 (오) 도금
은 (Ag) 도금
👉 Key requirement:
All materials must meet maximum concentration limits (typically 0.1% 또는 0.01%) for restricted substances.
What is RoHS Compliance?
RoHS 규제 (유해물질 제한) is a regulation introduced by the European Union to limit hazardous materials in electrical and electronic equipment.
Restricted Substances Under RoHS
| Substance | Limit |
| 선두 (납) | ≤ 0.1% |
| Cadmium (CD) | ≤ 0.01% |
| Mercury (수은) | ≤ 0.1% |
| Hexavalent Chromium (Cr6+) | ≤ 0.1% |
| PBB | ≤ 0.1% |
| PBDE | ≤ 0.1% |
| DEHP, BBP, DBP, DIBP | ≤ 0.1% |
Why This Matters for Terminals
터미널은 다음과 같이 널리 사용됩니다.:
와이어 하니스
Electrical assemblies
If terminals contain restricted substances:
Products can be banned from EU markets
Shipments may be rejected
Companies face legal and financial penalties
Why RoHS Compliance is Critical for Terminal Buyers
Market Access
Non-compliant terminals cannot be used in products sold in:
European Union
Many global markets following RoHS standards
Risk Reduction
Using compliant materials helps avoid:
제품 리콜
Compliance audits failure
Customer complaints
