Skip to main contentPortable sensor-interface-box from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 30, 12h quote, 30-day delivery to 47 countries.
Most Portable sensor-interface-box marketing claims do not survive a real-world drop test. Our cases do — because we test every batch to the same standard we publish, not to a 'design intent'.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP | Multimeter / Caliper |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+AS | Surveying Total Station |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+AS | Optical Microscope |
The most common model for "Portable sensor-interface-box" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP body).
Portable sensor-interface-box shells are rated -40°C to +80°C per MIL-STD-810H Method 501.7 (high) and 502.7 (low). Chemically resistant to petroleum, mineral oil, dilute acids, alcohols, and most industrial solvents. Not resistant to concentrated sulfuric acid, aromatic, or chlorinated solvents.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
In 2024, we shipped Portable sensor-interface-box for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
When evaluating Portable sensor-interface-box options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
Standard Portable sensor-interface-box: MOQ 30 units, 30-day production, T/T 30/70. Custom: MOQ 500 units, 25-30 days mold + 30 days production. We support L/C for >$20,000 orders. Sample lead time 5-7 days, sample cost refundable on >2,000 unit order.
If a competitor claims IP67 but cannot produce a third-party certificate, ask them why. We always can.
Established 2014. 13,000 sqm factory in Fusha Industrial Park, Zhongshan, Guangdong. 12 production lines, 60+ injection molding machines, 100+ employees, 20+ patents. Monthly capacity 80,000 units. Annual export revenue 8M+ USD to 47 countries.
Direct from the OEM. Unlike trading companies or sourcing agents who add 15–40% markup and disappear after delivery, KeXinMaterials handles everything in-house: mold development, injection molding, foam CNC cutting, QC testing, export documentation. Our 2024 buyer survey showed 87% repeat-order rate and 0.3% defect rate across 47 countries.

Anti-static foam option: surface resistance 10^6 to 10^11 Ω per ANSI/ESD S541. Standard foam is non-ESD. If you are transporting electronics (camera bodies, circuit boards, hard drives), specify anti-static foam.
UL94 V-2 standard (self-extinguishing within 30 seconds, no flaming drips). Higher UL94 V-0 rating available for select materials. We do not use materials with toxic flame retardants (Deca-BDE, HBCD) per ROHS.
Resistant to: petroleum products, mineral oil, dilute acids and alkalis, alcohols, and most industrial solvents. Not resistant to: concentrated sulfuric acid, aromatic solvents (benzene, toluene), and prolonged exposure to chlorinated solvents.
Standard PP case: density 0.91 g/cm³, so yes, all our cases float. Foam-filled case with typical payload (5-30kg equipment): overall density may exceed 1.0, may not float. Specify float requirement and we adjust foam density.
Standard cases: no EMI/RFI shielding. Optional: conductive coating (nickel or copper) on interior surface for EMI shielding per MIL-STD-285. Adds $5-15 per unit depending on size. Used for sensitive electronic equipment.
