QM PAG.1P.304.NLAC52NZ is a 1P‑format 4‑pin push‑pull self‑locking plastic connector designed for high‑reliability interconnection. It adopts grey PSU housing material, PA insulator, and tin‑bronze gold‑plated contacts to ensure stable electrical performance and long service life. With A‑type positioning key and fixed angle design, it effectively prevents misinsertion and ensures accurate mating. The connector is equipped with bend relief and collet cable clamping structure, which fits cable diameter from 4.5mm to 5.5mm, protects cable from bending stress and improves durability in dynamic use. It features compact outline, push‑pull self‑latching, quick mating and reliable locking, suitable for limited installation space. Key parameters include 0.9mm contact diameter, 8A rated current, 1200V AC withstand voltage, insulation resistance ≥5000MΩ and contact resistance ≤9mΩ. It meets medical safety and material compliance requirements, and is widely used in vital sign monitoring, diagnostic treatment, laboratory analysis, portable testing and industrial instruments.
Compact Push-Pull Self-Latching Connector
Ultra‑compact outline adapts to limited installation space. Push‑pull self‑locking realizes fast mating and reliable locking, effectively avoiding accidental release during equipment operation.
High-Performance PEEK Insulator
Insulator features excellent insulation and voltage withstand performance. Tin bronze gold‑plated contacts ensure low contact resistance and stable long‑term transmission.
Multiple Key Coding Anti‑Misinsertion
Supports multiple positioning key codes including A, B, C, etc. Different key positions and angles prevent mismating and ensure correct and secure connection.
Wide Cable Compatibility & Stable Strain Relief
Matched with multiple cable diameter ranges and equipped with professional bend relief. It protects cable from bending damage and improves service life in dynamic applications.
Compliance with Medical & Industrial Standards
We offer a variety of front nut colors for intuitive interface identification, equipment categorization, and brand differentiation. The color coating is durable and fade-resistant, combining practicality with clear visual recognition.
Disposable Medical Connector
Products meet relevant safety and material standards, suitable for medical devices, diagnostic equipment, portable instruments and other demanding applications.
