The R584-004-000 is a four battery holder for AA size cells from the R250 Series mobilCASE accessory range. It is listed among the series' cable gland and battery kits, which are used with collared end caps, and gives designers of portable, battery-powered equipment a way to power their device inside a mobilCASE extruded aluminum enclosure.

Collared end plates are the style used for accepting cables or batteries. In the series tables the collared plates are R581-080-000, R581-100-000 and R581-130-000, each listed for the one-piece closed extrusion of its profile. Choose the collared plate that matches your body profile, then fit the R584-004-000 to hold 4 AA cells.

The part data lists the material as aluminum and the colour as black. The manufacturer's short description is "ROLEC MOBILCASE BATTERY HOLDER" and its long description reads "hardware - ROLEC mobilCASE battery holder". If your design needs fewer cells, the R584-002-000 is the 2-cell AA version in the same kit table.

The shipping weight is 0.1 lbs (0.05 kg), and the part ships in a box. The R584-004-000 is RoHS and REACH compliant. AA batteries, the enclosure and end plates are ordered separately; the data describes this part only as a battery holder.
