Rugged IoT Sensor Node Enclosure Design

Project Title:
Mechanical Enclosure Design for Industrial IoT Wireless Sensor Node (IP67, Magnetic/Epoxy Mount)
Project Description:

Looking for an experienced mechanical/product designer to design a rugged industrial enclosure for a compact wireless sensor node used in industrial environments.

Two variants from one base design:

Permanently installed node — magnetic or epoxy mount
Handheld version — ergonomic grip, panel-mount connector on enclosure wall

PCB: 40×36mm

Target enclosure: ≤60×60mm footprint, minimal height

Mechanical requirements:

IP67 rated (dust-tight, 1m immersion)
Mounting options:
— Epoxy mount (flat base)
— Magnetic mount — N52 pot magnet, min 50N pull, either integrated or detachable magnetic base addon (like a snap-on magnetic puck the sensor sits into)
O-ring groove for lid seal
Single M8 connector port on enclosure wall (industrial connector)
No other ports or openings
LED diffuser window on top face
Snap-fit OR M2 screw assembly, no exposed fasteners on top
Min 2mm wall thickness
Designed for injection moulding long term — first prototypes via 3D print (PETG/ASA)

Deliverables:

Native CAD source file (any professional tool — Fusion 360, SolidWorks, Onshape, CATIA, Creo)
STEP file
STL files for 3D printing
2D drawing with GD&T
Exploded assembly render
Minimum 3 photorealistic renders (top, side, isometric)

Please include in your proposal:

Portfolio of IP-rated industrial enclosures you have designed
Your CAD tool and approach to O-ring sealing and snap-fit design
