Radionix D8225 Mini Mullion Proximity Access Control Reader

Place a proximity reader at a controlled opening where available mounting width is limited by the door-frame profile. The mini mullion format addresses narrow mounting areas commonly found beside doors, allowing the reader to serve as the credential presentation point for an access-control installation. A user presents a compatible proximity credential, and the reader performs the credential-reading function at that opening. Radionix D8225 suits physical-security projects that require a compact reader rather than a broad wall-plate format. Its mini mullion designation is the key selection detail: assess the usable mounting surface at each opening before standardizing on this reader style. Pair the reader with an access-control system and credential population appropriate to the site. The reader selection should match the physical constraints of the door opening as well as the site access-control design. Use it for employee entrances, internal controlled rooms, and other door locations where proximity credential presentation is required and frame area governs reader placement. It focuses on credential presentation at one access point. Keep the reader choice aligned with the controller, credentials, wiring method, environment, and mounting arrangement used at the opening. This preserves a compact reader location while maintaining the site’s established access-control architecture.
