Waterproof Junction Box — IP65 ABS/PC with Stainless Latches (WBG Series)
IP65 waterproof junction box with silicone gasket and corrosion-resistant stainless-steel latches.
Durable ABS base with PC clear or opaque lid; UV-stable, impact-resistant.
Pre-marked knockouts for cable glands (e.g., M20/M25) and molded bosses for accessories.
Optional backplate/DIN-rail kit for fast device mounting; wall/surface mount ready.
Wide size range (approx. 120×90×70 mm up to 630×530×250 mm) to cover small splices to large assemblies.
Overview
The WBG Series is a durable, field-ready waterproof junction box designed to keep
connections clean, dry and serviceable. A tough ABS base provides structural rigidity while the polycarbonate lid
offers either clear visibility for fast inspection or opaque shielding when you want to block light. A continuous
elastomer gasket and over-center stainless latches compress the seal evenly, delivering reliable IP65
protection against dust and water jets in sheltered outdoor areas and industrial wash-down zones.
Inside, molded bosses accept an optional backplate or a 35 mm DIN rail so
terminal blocks, power supplies, breakers or I/O can be mounted neatly. Pre-marked knockouts on the side walls make
entry planning straightforward—fit the correct cable glands and blank any unused holes to maintain the IP rating.
The flat mounting back and rounded edges simplify wall or machine-skid installation and keep the cabinet looking
professional after service.

Typical Applications
- Automation nodes and sensor/actuator terminations; building management & HVAC splices.
- Outdoor sheltered areas: façades, rooftops, equipment skids, pump rooms, treatment plants.
- Low-voltage controls, power distribution tap-offs, lighting and signage connections.
Installation Guidance
- Mount the enclosure vertically and use all fixing points; support heavy cables to reduce strain.
- Open only the knockouts required; use properly sized glands and blank unused entries to keep IP65.
- Close latches evenly to compress the gasket; avoid solvent cleaners that may craze PC lids.
- Label circuits and record gland sizes/torques in the job sheet for maintenance.
