Access Unit 125kHz Reader

The 2N Access Unit 2.0 RFID 125kHz 9160341 combines a contactless RFID reader and access controller in one network-connected device. Designed for projects using compatible 125kHz credentials, it provides a practical way to modernise access control while allowing users to retain suitable existing cards.

Its integrated controller removes the need for a separate external access controller. This simplifies the system layout and makes the unit suitable for residential entrances, offices and other controlled doors where straightforward card access is required. Existing credentials should be checked for compatibility before planning their reuse.

Network connectivity and power can be provided through a single Ethernet cable using IEEE 802.3af PoE. An external 12V DC supply is also supported, giving installers flexibility to suit the available infrastructure.

The unit provides an active lock output, a relay with normally open and normally closed contacts, and two inputs for integration with door hardware and monitoring accessories. An integrated tamper switch detects unauthorised opening. Additional compatible modules can extend the installation as requirements develop.

With IP54 ingress protection, IK08 impact resistance and an operating temperature range of −40°C to +60°C, the Access Unit 2.0 is designed for demanding entrance environments. Surface and flush mounting options allow the finished installation to suit the building, using the appropriate mounting accessories.

This SKU is the 125kHz RFID version. It is suitable where retaining compatible low-frequency credentials is a priority when moving to an IP-based access control system.
