Metal connectors fail where it matters most—salt spray, humidity, and chemical vapors attack plating, seize threads, and degrade seals, leading to unplanned downtime and expensive replacements. Reunion's M16 series plastic waterproof connector eliminates this vulnerability at the material level.
The housing is precision-molded from high-strength PA66 thermoplastic. It does not rust, oxidize, or suffer galvanic corrosion. In-house salt spray testing per ASTM B117 shows zero surface degradation after 240 hours—while equivalent nickel-plated brass connectors exhibit pitting and white rust within 48–72 hours.
Beyond corrosion resistance, this M16 series plastic waterproof connector delivers:
Up to 60% weight reduction vs. brass equivalents—reduces cantilever load on PCB mounts and panel brackets.
IP67 sealing (1m, 30 min immersion batch-tested per production lot)—ideal for flood-prone outdoor cabinets, offshore sensors, and coastal lighting poles.
Wide temperature range: -40°C to +105°C, covering arctic cold and equatorial solar gain.
Experience (EEAT) is not hypothetical. In Q1 2026, a marine instrumentation integrator servicing North Sea offshore platforms replaced 86 brass M16 connectors with Reunion's plastic series after 18-month field trials. Results documented:
Zero corrosion-related failures across 14 months of continuous salt-fog exposure. And the thread integrity maintained through 300+ mating cycles during annual sensor recalibration.
Signal integrity stable: Contact resistance remained ≤3.5mΩ (initial spec ≤3mΩ) without intermittent faults reported in RS-485 data links.
Another case: A coastal tunnel LED lighting project in Southeast Asia deployed the hybrid 2+4 pin variant of the M16 series plastic waterproof connector to combine 10A power delivery with DALI dimming signals in a single cable run. The contractor reported 40% faster installation and eliminated separate signal conduits. After 22 months of monsoon rains and tidal humidity, no connector replacement was required—contrasting with the previous metal-spec project where 30% of connectors showed green oxidation within 12 months.

The engineering conclusion is clear: the M16 series plastic waterproof connector from Reunion delivers the corrosion-proof longevity of premium plastics at a cost structure that rewards volume procurement—without the weight penalty or failure modes of metal.
Reunion's quality system is audited annually by third-party registrars. We publish the following active certification numbers (available for download on our website):
| Certification | Scope |
| ISO 9001:2015 | Design, production, after-sales |
| ISO 14001:2015 | Environmental management (waste reduction, sustainable molding) |
| ISO 13485:2016 | Medical device quality—applicable for diagnostic/monitoring equipment using the M16 series |
Yes—the contact layout separates power and signal pins with a physical barrier (molded isolation wall) and a center-to-center spacing of 4.5mm (power-to-signal), exceeding the creepage requirements for 250V/50V mixed circuits per IEC 60664-1. In our internal EMC pre-scanning, crosstalk at 1MHz was < -60dB. The hybrid M16 series plastic waterproof connector is already deployed in commercial DALI-based street lighting projects with 25,000+ units in the field (2025–2026 installations).
Reunion offers a 1-year limited warranty covering housing cracking, thread stripping (under specified torque), and sealing failure under IP67 conditions—provided installation guidelines are followed. For corrosion-related claims (rust/oxidation), the warranty is unconditional for the housing material because PA66 is inherently non-corroding. Warranty claims are processed with a cross-shipment advance replacement program for approved distributors and OEM accounts.
Yes—we maintain a sample stock of all pin configurations (including 2+4 hybrid) for next-business-day dispatch via DHL/FedEx. Sample pricing includes a dedicated test report package (salt spray, waterproof, and contact resistance measurements specific to that batch). MOQ for standard samples is 1 piece. For custom cable assemblies or termination variations, sample lead time is 10~15 days.
