Zhejiang Yulian Technology Co., Ltd. (YLCNC) is a premier B2B manufacturer. We specialize in high-performance 5 Pin Connectors for demanding automotive and industrial environments. As a trusted supplier, we engineer robust solutions to maintain secure electrical connections under extreme conditions. Whether you are assembling heavy-duty wire harnesses or sourcing reliable commercial vehicle components, our extensive product lineup delivers uncompromising durability. We focus on supplying IATF 16949 certified, OEM-quality connectors and custom terminals tailored for bulk procurement.
Procurement managers and engineers often search by specific connector families rather than generic pin counts. To support this, we have organized our automotive connectors by industry-standard series. Review the table below for a quick comparison of our primary product families. Then, explore the detailed specifications of each series.
| Connector Series | Key Features | Ideal Applications |
|---|---|---|
| DEUTSCH (DT, DTM, DTP) | Heavy-duty, waterproof, rugged housing | Harsh environments, off-highway wiring |
| AMP SUPERSEAL 1.5 & Ampseal 16 | IP67 environmental sealing | Sensor applications, automotive harnesses |
| LEAVYSEAL & DRC Series | High-vibration resistance, robust locking | High-current commercial vehicles |
| MQS 0.63mm Series | Space-saving, high-density design | Automotive signal connections |
Our DEUTSCH series connectors encompass the DT, DTM, and DTP lines. We engineer these specifically for harsh environments. These heavy-duty, waterproof components provide exceptional reliability for wire-to-wire and wire-to-board connections. Designed to withstand severe vibration, moisture, and temperature fluctuations, they are the standard choice for off-highway wiring systems.
For applications requiring superior environmental sealing, our IP67 waterproof Ampseal 16 and AMP SUPERSEAL 1.5 series deliver outstanding performance. These connectors are highly favored for critical sensor applications. They also excel in complex automotive wiring harnesses where preventing water and dust ingress is paramount.
When dealing with high-vibration and high-current demands, our custom robust DRC and LEAVYSEAL series offer unmatched durability. Tailored specifically for heavy-duty commercial vehicles, these connectors feature secure locking mechanisms. Their rugged housings prevent accidental disconnects in the most demanding operational environments.
Space constraints in modern vehicle architectures require compact yet reliable solutions. Our premium MQS 0.63mm series is designed for space-saving, high-density automotive signal connections. They provide secure data and low-current transmission without compromising the mechanical strength required in automotive engineering.
Partnering with a direct manufacturer ensures consistent quality, scalable production, and competitive pricing. YLCNC brings 18 years of production experience to every batch of 5 Pin Connectors we manufacture. Operating out of two modern manufacturing bases, we guarantee stable mass production capabilities. This allows us to meet the high-volume demands of global B2B clients. Our commitment to strict quality control is validated by comprehensive industry certifications.
Our versatile 5-pole connectors are deployed across a wide spectrum of demanding industries. We engineer our housings and terminals to withstand mechanical stress, chemical exposure, and weather extremes. They provide secure links for engine control units, lighting systems, and diagnostic interfaces.
These connectors excel in commercial vehicles, construction machinery, and agricultural equipment. In the rapidly growing new energy sector, our products ensure safe power and signal routing. Furthermore, they are widely utilized in off-highway equipment and industrial machinery. A prominent specialized application includes our heavy-duty NOx sensor connector housings. These are critical for maintaining the efficiency of modern emissions control systems.
