Surface-Mount Enclosure Elfon OPTIMA OP-ON2B-G — model OP-ON2B-G

Elfon OPTIMA OP-ON2B-G is a surface-mount enclosure designed to house electronic modules and installation components on walls or other flat surfaces. The OP-ON2B-G model provides a compact protective casing that helps organise wiring, protect low-voltage electronics from accidental contact and offer a stable mounting platform for small control units, access panels and alarm modules. The enclosure is intended for indoor use where surface mounting simplifies installation without the need for recessed mounting.

Advantages

The enclosure offers a robust protective shell that reduces exposure to dust and accidental disturbance while maintaining easy access for installation and maintenance. Its compact footprint and flat rear surface make attachment to walls straightforward, and the design supports tidy cable entry and exit. Materials and finish are chosen to provide electrical insulation and mechanical protection appropriate for low-voltage electronics.

Suitable for

• Small control units and programmable logic modules
• Access control panels and card readers
• Alarm and security system modules
• Sensor interfaces and low-voltage power supplies
• Prototyping and small-scale installation projects

Key specifications

• Mounting type: surface-mount for walls or flat panels
• Application: housing for low-voltage electronic modules and installation components
• Protection: provides basic protection against dust and accidental contact (indoor use)
• Design: compact rectangular enclosure with flat rear face for secure attachment
• Cable management: provisions for neat cable entry and exit to facilitate wiring
• Materials: non-conductive plastic suitable for electrical insulation and mechanical protection

How to use

Position the enclosure on the chosen mounting surface and mark fixing points using the rear face as a template. Drill or prepare the surface as required for the chosen fasteners, then secure the enclosure firmly to the wall. Route cables through the provided entry points and fit modules inside, fastening them according to their manufacturer instructions and ensuring secure cable connections. Close the enclosure and verify that no wiring is pinched and that access panels or covers are properly seated. Perform a functional check of the installed electronics after mounting.

Usage recommendations

Use the enclosure for indoor, low-voltage applications and avoid exposure to prolonged moisture or direct outdoor weathering. Select appropriate cable glands or grommets if additional strain relief or improved sealing is required, and ensure ventilation or spacing if installed components generate heat.
