Surface-Mounted Enclosure Elfon OP-ON2A-G for Optima series, model OP-ON2A-G

Elfon OP-ON2A-G is a surface-mounted enclosure from the Optima series designed to house electrical or electronic modules. The enclosure is intended for indoor wall-mounted applications where a compact and secure casing is required for controllers, sensors, small power supplies or other low-voltage devices. It provides rigid protection for housed equipment while allowing organized cable entry and secure fixation to a vertical surface.

Advantages

The enclosure offers a compact footprint and a design tailored for surface installation, reducing the need for recessed mounting. Its construction ensures safe separation of internal components from the environment and simplifies wiring access. The Optima series design supports quick fixation to flat surfaces and provides stable mechanical support for mounted modules, contributing to orderly installation and reduced installation time.

Suitable for

• Mounting control modules and small automation controllers on walls
• Housing sensors, relays and terminal blocks in indoor installations
• Enclosing small power supplies or DC converters in service cabinets or technical rooms
• Temporary or permanent surface-mounted installations where recessed boxes are not feasible

Key specifications

• Type: surface-mounted enclosure for electrical/electronic modules
• Series: Optima (compact design for wall mounting)
• Typical use: indoor installations, wall-mounted
• Mounting: designed for secure fixation to vertical surfaces
• Cable entry: provisions for organized wiring and cable access
• Protection: mechanical protection for internal modules during normal indoor use

How to use

Choose a suitable mounting location on a stable vertical surface, ensuring access for cable routing and maintenance. Detach the enclosure cover according to the manufacturer’s instructions, position internal modules or PCB mounting hardware inside, and secure them with the provided mounting points. Route cables through the designated entry points and fasten the enclosure to the wall using appropriate screws or anchors for the substrate. After final wiring and functional checks, replace and secure the cover to complete the installation.

Usage recommendations

Use the enclosure indoors and avoid exposure to direct weather conditions. Ensure that internal components do not exceed the enclosure's intended thermal and electrical limits and maintain correct clearances for ventilation and cable bending radii. Select appropriate sealing or grommets for cable entries if additional protection against dust or moisture is required.
