FAQs: Custom Sensor Housings for Robotics Applications

Custom sensor housings are application-specific enclosures that protect the vision systems, force sensors, encoders, and environmental sensors embedded in robotic systems. For example, some housings are camera vision enclosures that include optical window mounts and lens protection. Other housings enclose force-torque sensors and include load transfer interfaces, encoders, a nd protect optical disks and electronics from contamination, environmental sensors, and incorporate ventilation and moisture barriers, multi-sensor integration housings, and combine multiple detection devices, junction boxes for sensor signal distribution, and custom-contoured enclosures that fit unique robot geometries or that address space constraints.

Aluminum 6061-T6 provides lightweight construction, excellent thermal conductivity for heat dissipation, natural EMI shielding, and easy machinability for complex geometric fabrication with integrated mounting features. For washdown environments, stainless steel offers excellent corrosion resistance and EMI shielding effectiveness exceeding 60 dB, and structural rigidity for industrial applications. Die-cast aluminum enables cost-effective high-volume production with complex internal features and good thermal properties. Engineering plastics, including ABS and polycarbonate, provide electrical insulation, chemical resistance, lightweight construction, and impact protection for non-metallic enclosure requirements.

To manufacture custom sensor housings, complex three-dimensional enclosures are created using multi-axis CNC milling, which also integrates mounting bosses, cooling fins, channels for cable routing, and even additional enclosures. Precision boring machines dimension control for sealing interfaces and O-ring grooves, which helps in achieving an IP65 or IP67 rating. Thread cutting creates closure and cable gland threads, and pocket milling carves out internal cavities for mounting sensors and electronics. Cross-drilling creates cable entry ports and ventilation holes, while face milling offers horizontal sealing surfaces. For the installation of lenses or glass, window pocket machining cuts optical apertures to precise measurements.

We achieve specific tolerances such as for sealing grooves, O-ring compression, and thread for cable gland retention, which are ±0.002 inches, mounting holes for sensor alignment, which are ±0.005 inches, span, and overall dimension of housing ±0.010 inches for consistent protection IP54, and integrated sensor ±0.015 for reliable protection rated IP67.

Yes. We offer flexible manufacturing capabilities including:
Rapid prototyping for design validation
Low-volume production for specialized applications
High-volume production with consistent quality control
Full structural and dimensional verification at every stage

All components are manufactured under an ISO 9001 quality management system, including complete material traceability, dimensional verification, and documented proof of pressure testing, IP validation, environmental sensing, robotics cag,s EMI shielding, and thermal management sensor enclosures tracing for reliable traceability protection.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

Standard sensor housings with basic features require 8–12 business days; more intricate enclosures, such as multi-cavity designs with integrated thermal management, require 3–4 weeks, accounting for both machining and surface treatment. However, for rapid environmental testing and sensor integration validation, I can have prototype runs ready in 5–8 days.

Yes. We create hermetically sealed enclosures for underwater robotics, achieving an IP68 rating and the ability to operate at 10 meters depth. We also construct enclosures for welding robots that withstand 100°C ambient conditions, explosion-proof enclosures for hazardous locations per ATEX and Class I Div 1 standards, and EMI-shielded enclosures that provide more than 80 dB of shielded effectiveness for high EMI environments. Additionally, we make ruggedized housings that comply with MIL-STD-810 for shock and vibration in mobile robots.

Correctly designed seal groove dimensions guarantee sufficient gasket compression, resulting in an achieved IP65 or IP67 seal. This prevents moisture and dust ingress that would damage the sensor electronics. Accurately sized threads provide stable installation of the cable gland and maintenance of the seal under vibration and thermal cycling. Flat sealing surfaces within 0.005 inches provide sufficient uniform contact of the gasket, thus eliminating potential leak paths. Varying wall thicknesses, and thus having controlled wall thickness, guarantee sufficient EMI shielding of 40 to 60 dB typical in sensor signals from industrial motor drives and welding equipment. Ventilation designed with labyrinth seals provides pressure equalization that prevents seal failure from thermal expansion, all the while maintaining contamination protection. Features that incorporate fins and conductive paths provide thermal management that keeps sensor electronics below an operating temperature of 60°C.
