Application — Medical & Lab — Waterproof Connector Manufacturer Since 2002
Precision Connectors for Medical & Lab Instrumentation
Built by YXY — waterproof connector manufacturer since 2002 · 东莞工厂
用于诊断设备、便携式监护仪、手持探头与台式分析仪的低压信号与电源互连 — 在这些应用中，漏电流、接触电阻与耐清洁性直接影响临床可靠性。采用镀金接触件、光洁易擦外壳与 IP65 以上密封的紧凑型微型圆形连接器，适用于消毒环境。
适用场景
YXY 微型连接器在设备内部的应用位置
Not the mains inlet — these are the 3–8 wire links between sensor head and mainboard, battery dock and handheld, consumable cartridge and reader. Failure shows up as intermittent readings, not a tripped breaker, so contact stability matters more than ampacity.
诊断与影像外设
超声探头、心电/脑电导联集线器、脉搏血氧仪模块、皮肤镜、口内扫描仪。 4–7 contacts carry micro-volt sensor signals, 5V bias and shield. The cable flexes thousands of times; the connector must hold less than 10mΩ drift after flex. SP11 threaded micro with strain-relief overmold prevents cable-break artifacts.
便携式与可穿戴监护仪
便携式心电图机、动态心电仪、输液泵手柄、CPAP 管路、可穿戴血氧仪。 The 08mm YM08 or Push-Pull breakaway is preferred over threaded — one-handed blind mating, 200g retention, no cross-threading in gloves. Low mating force of 4–8N with an audible click.
实验室与 IVD 台式分析仪
血气分析仪、PCR、免疫分析、离心机盖联锁、移液工作站。 The connector sits behind a drip tray — it needs an IP65 front seal and rear potting-friendly solder cups. 1.5A per pin handles valve and solenoid pull-in; gold plating prevents fretting from lab vibration.
治疗及邻近灭菌区域应用
高频电刀手柄、内窥镜主机、洁牙机、灭菌柜旁的 docking 托盘（仅可擦拭）。 外壳必须耐受每日 70% 乙醇、异丙醇与季铵盐擦拭。采用光洁镀镍黄铜与低烟无卤注塑 — 没有涂层可剥落。不适用于植入式设备。
范围说明： YXY 提供 设备与仪器互连 — 探头线缆、对接座、内部线束 — 不适用于有源植入式或 III 类直接接触患者的侵入式连接器。材料为工业级、接近生物相容性要求（合规说明见下文），并非通过 ISO 10993 植入接触认证。对于接触皮肤的手柄，我们建议采用注塑出线口与内缩式接触件。
设计要求
淘汰通用件的设计要求
Medical handles are measured in grams and millimeters. A “waterproof IP68 outdoor” connector is usually too big, too stiff and too rough. These are the gates a medical micro connector must pass before it ever sees a BOM.
| 要求 | YXY 微型规格 — 为什么它在临床上很重要 |
|---|---|
| 外形紧凑 | Ø8–11mm mating, <18mm cable OD. Fits 20–24mm probe handles and 38mm IVD cartridge slots without crowding the thumb grip. 0.75mm thread pitch for short engagement. |
| 接触件表面处理 | Gold 0.2–0.5µm over nickel 1–2µm on copper alloy. Keeps contact resistance <5mΩ initial, <10mΩ after 500 cycles and 40°C/93%RH. Prevents the fretting oxides that masquerade as sensor drift. |
| 电流 / 电压 | 每芯 1.5 A / 50 V DC（30 V AC），4 芯时降额至 0.5 A。 覆盖 5V/12V 辅助电源、RTD/热敏电阻偏置及 12V 电磁阀/阀门峰值电流。500V AC 耐压，绝缘电阻 >1000MΩ。 |
| 耐久性 | ≥500 cycles (SP11/YM08), 1000–5000 for Push-Pull metal. A ward device mated 4×/day × 250 days = 1000 cycles/year. Tested per IEC 60512-9a, ±10µm wear on gold. |
| 密封 | 插合状态 IP65（可擦拭）至 IP67（防喷溅/滴水）。 硅胶 O 型圈 + 尾部密封套。可承受每日乙醇/季铵盐擦拭与 1 m 滴水。非 IP68 浸没等级 — 未插合端不密封，请置于滴水盘内侧。 |
| Temperature & cleaning | −25 to +80°C operation, PA66/metal shell. Withstands 70% ethanol, isopropanol and CaviWipes-type quats. No autoclave (134°C steam) — specify stainless + glass-seal if needed. |
| 结构 | Push-Pull 4–8N mate / 8–15N unmate; threaded 0.15–0.25Nm. 15° blind-mate chamfer with mis-mate prevention key. Cable flex >5000 × 90° at 50mm radius. |
Test conditions: 20°C, 45%RH, 1.5A load, 2mΩ lead compensated. Derate current 20% for 6+ pins bundled. IP ratings per IEC 60529, mated with a YXY cable assembly; panel-cutout tolerance ±0.05mm.
外形尺寸与搬运 — 易被忽视的指标
- 重量： 2.1g（YM08 面板座）/ 4.8g（SP11 线缆端）— 探头保持中性平衡。
- 插合长度： YM08 仅 15.5 mm，SP11 19 mm — 密集面板上不会碰手。
- 戴手套操作测试： the M14 knurl works with 6mil nitrile; the YM08 snap works with double-gloving.
- 线缆外径： 3.2–4.5mm PUR/TPU — soft touch, drag under 40g on neonatal probes.
- 颜色： 镍色/黑色外壳，白色/蓝色绝缘体 — 光学部件附近不使用黑色含炭材料。
来自现场退货的信号完整性分析
- Twist pairs for ECG/EEG: 2× twisted + drain — use the 5-pin (4 signal + shield) Push-Pull 5B.
- 手柄内非屏蔽尾线请控制在 18 mm 以内 — 相比 40 mm 可降低约 8 dB 的 50/60 Hz 感应干扰。
- 推拉自锁接地针先接触后断开：1 号针长 0.3 mm。
- Overmold with 35A shore TPE at the cable exit: passes a 1.2m drop onto steel and a −20°C crack test.

推荐系列
为手持设备和台面设计，而非灯杆
Three families cover 90% of 0.5–1.5A medical harnesses. All share gold contacts, silicone seals and PUR/TPU cable options — panel + cable, male/female, solder and crimp. Pick the lock that matches the workflow, not the datasheet max.
SP11 微型圆形 — 实验室的主力型号
When the device sits on a bench and the user has two hands. Positive threaded lock (0.2Nm), no accidental pull. 2–7 pin, 1.5A/50V, IP65 mated with a silicone O-ring. Smooth brass/nickel shell wipes clean; the rear grommet accepts 3.2–4.5mm PUR. Solder cup and crimp options for field repair.
适用于： 体外诊断分析仪盖板线束、离心机联锁、超声探头插槽、实验室移液头。在空间受限处替代户外 M12。

推拉自锁金属圆形 — 为不停机运行的线缆而生
Chrome-plated brass, collet strain relief and a 45° blind-mate chamfer for high-cycle wards. 2–7 pin, 1.5–2A, IP50 (0B) to IP65 (sealed 1B). 1000–5000 cycles, latch fatigue rated, keyed to prevent a 5-pin into 4-pin mis-mate. The cable collet holds 30N pull.
适用于： 床旁监护仪主干线、心电集线器分线器、每日再处理的治疗手柄。在液体管路 30 cm 范围内请指定密封 1B 型。
查看推拉自锁金属系列Also available — panel & cable done as a system
我们成对发货，而不只是外壳 — 这样密封才真正起作用：
- 面板端： 螺母 + O 型圈 + 防转扁位，PCB 焊杯 / 弯角 / 压接，可选后部灌封杯。
- 线缆端： pre-wired 0.3–2m PUR/TPU, shield drain terminated, 35A TPE overmold, custom length and labeling.
- 转接头： SP11 转 YM08 尾线，用于旧款分析仪改造 — 无需重新开面板孔。
- 解决方案： use the YXY mated pair; mixing with generic M8/M12 risks a 0.15mm pin offset and a resistance jump.
我们如何为医疗微型件报价
- 按芯数起订 50 只（评估可 10 只）— 医疗项目从 50 只起步，而不是 1,000 只。
- Samples in 5–7 days, with 2D + STEP + contact layout, all on one lot so your verification is not a lottery.
- 随附面板开孔 DXF 与禁布区 — 不与手柄干涉。
- Batch code + date on the shell; COC with contact resistance and IP lot test.
合规
Biocompatibility & compliance — plain language, not copy-paste
These are not implantable connectors. For handles, benches and docking — where the user wipes down daily and the patient touches only the overmold — here is what we do and what we don’t claim.
Materials & skin-contact notes
- 接触件： C3604/CuSn copper alloy, gold 0.2–0.5µm over nickel 1–2µm. No cadmium, no cobalt binder. Low nickel exposure — the contact tip is gold-covered; the shell is not skin-worn.
- 外壳： HPb59-1 brass with bright nickel 5–8µm, or PA66-GF for the insulated panel. No latex, no phthalate plasticizer in standard PUR/TPU cable.
- 绝缘体： PPS / LCP, UL94 V-0, CTI >175, glow-wire 750°C. White/blue through-color — no paint near the fluid path.
- 密封件： silicone VMQ O-ring, −40 to +180°C, compression set <15% at 70°C.
- 注塑成型： halogen-free TPE 35A, skin-touch tested; cytotoxicity report on request for the TPE lot, not for the metal shell.
未声明事项： ISO 10993-5/-10、USP Class VI 或 ISO 13485 体系认证针对的是整机而非连接器本身。若您的设备需要这套合规链，我们可提供材料批次 CoA 与镀层厚度报告供您归档 — 并可选用您已认证的注塑材料生产。
Regulatory & lot paperwork — what ships with the box
- REACH & RoHS: fully compliant, SVHC <0.1% per current candidate list, lead-free solder cups, Cr(VI)-free plating. REACH/RoHS declaration per lot + SGS on file (annual).
- UL： insulator resin UL94 V-0, file E* on request; the connector is component-level, not a UL-listed end device.
- 可追溯性： laser lot code on shell, date code on bag; COC with 4-wire contact resistance, insulation and IP sample test (AQL 1.0).
- 镀层审核： gold thickness 100% XRF-sampled, not batch-averaged — min 0.2µm, typ 0.35µm on SP11, with a nickel barrier against copper migration at 85°C storage. Report ships in the bag.
- PFAS 说明： no PTFE on standard seals or cables; PTFE-free BOM available for PFAS-restricted tenders.
清洁兼容性（擦拭，不可浸泡）
- 已验证擦拭方式： 70% 乙醇 / 70% 异丙醇，作用 5 分钟，500 次循环无微裂纹。
- 常见季铵盐湿巾： benzalkonium & didecyl dimethyl ammonium (CaviWipes-type) pass with no stress cracking on the shell. Nickel may show a faint rainbow after repeated quat — functional, not corrosion; rinse with DI water if cosmetics matter.
- 不适用于： autoclave 121–134°C steam, gamma >25kGy, or prolonged soak. For those we quote glass-seal hermetic or 316L stainless builds separately.
- 易于擦拭的外形设计： the SP11 knurl is 0.5mm-pitch fine diamond (one-stroke wipe), Push-Pull metal has no knurl at all, and the panel O-ring sits behind the bezel so fluid runs off, not into the PCB cavity. PUR jacket swells <3% in 70% IPA and stays flexible at 4°C.

擦拭清洁与再处理
按推车工况设计，而非灭菌釜
在病房和实验室，连接器是在患者之间擦拭消毒，而非高压灭菌。其失效模式是滚花处残留物逐渐积聚，导致插合发涩，护士强行插合 — 把针弄弯。我们的设计就是要避免这一点，并为您的说明书提供相应文件。
| 规则 | 擦拭与搬运指引 |
|---|---|
| 注意事项 | Daily wipe with ethanol/IPA or a quat wipe, 30s dwell, soft cloth. Mate with the YXY cable only; replace the cable if the O-ring is nicked. |
| 注意事项 | 在湿区工作台上，请用 YXY 防尘帽盖住未插合的面板座 — 防止喷溅进入接触件。 |
| Don’t | 高压蒸汽灭菌、戊二醛浸泡或超声清洗组件 — 液体会渗入绝缘体。 |
| Don’t | Mate with saline on the pins — wipe dry first; salt crystals raise contact resistance by 50–200mΩ. |
供您说明书使用的再处理说明
如果您的设备说明书（IFU）需要连接器的清洁说明，我们提供一段可直接粘贴的擦拭流程 — 含已验证的化学品、作用时间与干燥时间。这不是灭菌声明：仅是针对非无菌附件的清洁兼容性说明。索取 《YXY 医疗擦拭说明 EN-2025》.
