Product Overview
The F Series is a broad waterproof electrical junction box family for projects that need a compact or medium-size ABS enclosure with multiple mounting and cover configurations. The catalogue shows standard screw-cover versions as well as models with mounting ears, which can simplify external mounting when the installation does not permit drilling through the enclosure body.
The catalogue specifies IP66 ingress protection and IK08 impact resistance, together with CE and RoHS. These ratings describe the enclosure series; the final installation should also use suitable cable entries and mounting practices for the intended environment.

Available Sizes and Configurations
The catalogue covers a large range from small connection boxes to larger electrical enclosures. The model chart below consolidates the standard dimensions and also shows representative cover and mounting-ear options.
Model dimensions in the catalogue range from compact 63 × 58 × 34 mm enclosures up to 380 × 260 × 140 mm configurations. Because usable internal space is smaller than the external dimension, component height, cable bending radius and gland position should be checked before final model selection.

When to Use a Model with Mounting Ears
A model with external mounting ears can be useful when the enclosure needs to be fixed to a wall, machine frame or support plate without placing mounting hardware through the protected internal space. A model without ears provides a cleaner external profile. The mounting method should be chosen together with the required enclosure size and cable-entry direction.
Typical Applications
- Industrial equipment: protected wiring connections, sensors, relays and compact control components.
- Outdoor electrical connections: junction points where an IP66 enclosure is appropriate for the complete installation.
- Communication and monitoring equipment: protected space for field wiring and auxiliary devices.
- OEM equipment: custom opening layouts for connectors, glands, switches or indicators.
For protection-level selection, see the IP-rated waterproof junction box selection guide.
Customization for OEM Projects
- Custom opening positions for cable glands, connectors and other components
- Selection of enclosure size and mounting-ear configuration
- Gray or transparent cover selection
- Other enclosure colors for larger-quantity projects
If enclosure material is part of the design decision, the ABS vs polycarbonate enclosure material guide provides additional selection context.
Selection Checklist
- Confirm the internal component envelope. Allow clearance for terminals, relays, PCB assemblies and wiring.
- Choose the mounting style. Decide whether external mounting ears are needed.
- Plan cable entries. Confirm gland size, quantity and entry direction before machining.
- Confirm the required IP rating. Match IP66 to the actual installation conditions and complete assembly.
- Select the cover configuration. Choose gray or transparent according to visibility requirements.
