Cover and base plates

Three version of the cover and base plates of the plug-in units PRO are available:

• a plainly cut perforated plate
• a closed sheet und
• a special perforated sheet, into which guide rails for the PCBs can be clipped in an HP grid.

The plain perforated plate and the closed versions are the more inexpensive alternatives. They allow installation of only one PCB (Slot 1), which in many applications is sufficient. The cover and base plates of the plug-in unit PRO are NOT bolted to the extruded side panels; instead they are inserted in grooves, which considerably facilitates assembly.

The rear panel as well as the cover and base plates are made of 1.5 mm sheet steel, which provides the necessary stability even in larger plug-in units. The rear panel is flat, which makes it easy to machine. It is also available in three versions: closed; for one connector to DIN EN 41612, and for several DIN connectors.

The perforated cover plate for guide rails ensures airflow of 60%, the plain cover plate airflow of 65%.
