This compact HID ProxPoint Plus Black Mini Mullion Access Control Reader mounts easily, features potted electronics and is designed to be used indoors—or outdoors. The proximity reader has a 125 kHz transmit frequency, and enables various beeper and LED configurations, depending on your site needs. The device is compatible with most access control systems and can be mounted directly on metal without affecting read range performance. The HID ProxPoint Plus mini mullion reader is cost-effective and provides reliable performance. A proximity reader is part of an overall access control solution that would also include a door controller, door hardware and accessories.
