Key Capabilities
Dual-Frequency RFID Support
Reads both 125 kHz and 13.56 MHz RFID cards and keyfobs, allowing sites that operate mixed credential environments to consolidate onto a single reader without replacing existing access cards or issuing new credentials to all users.
PoE-Powered Installation
Powered via PoE 802.3af (Class 0, up to 12.95 W) over a standard Cat-5e or better LAN cable, eliminating the need for a separate power run to each reader position and simplifying installation in structured cabling environments.
IP54 and IK08 Rated Housing
The zinc cast frame carries an IP54 dust and splash resistance rating alongside an IK08 impact resistance rating, making it appropriate for entry points exposed to weather, public access, or environments where physical interference is a concern.
Inbuilt Tamper Switch
An integrated tamper switch triggers an alert if the reader housing is removed or interfered with, adding a layer of physical security integrity at every access point without requiring an external tamper contact or additional wiring.
Wide Operating Temperature Range
Rated to operate from -40 to 60 degrees Celsius, this unit is suitable for installation in cold stores, outdoor vestibules, loading dock entries, and other environments where temperature extremes are a factor in hardware selection.
Best For
- Mixed Credential Sites: The dual 125 kHz and 13.56 MHz RFID support allows organisations with existing legacy cards to integrate newer credentials without a full re-issue programme.
- PoE-Structured Installations: Sites already running Cat-5e or Cat-6 cabling infrastructure can power and connect this reader over a single cable run, reducing installation time and hardware cost per access point.
- Exposed or Semi-Exposed Entry Points: The IK08-rated zinc cast housing and wide temperature tolerance make this unit suited to external doors, covered entry vestibules, and industrial access points where standard readers would not hold up.
Why Choose the 2N Access Unit 2.0 RFID Multifrequency
Where many RFID readers support only a single card frequency, the 2N Access Unit 2.0 RFID Multifrequency handles both 125 kHz and 13.56 MHz in one unit, removing a common compatibility obstacle during system upgrades or multi-tenancy deployments. The zinc cast frame, IP54 weatherproofing, and IK08 impact rating mean this is not a standard indoor-only reader: it holds up at entry points that see regular physical contact or exposure to the elements. PoE 802.3af support keeps wiring straightforward for integrators working in structured cabling environments, while the inbuilt tamper switch and passive or active switch outputs provide the connection points needed for door lock control and alarm integration. Available through Security Wholesalers, this unit suited commercial and industrial installations where reader durability and credential flexibility were both required. Note that this product has been discontinued, so availability should be confirmed before specifying it in a new installation.

Ideal Use Cases
Commercial Office Entry
Wall-mounted at office entry doors, the PoE-powered design and RJ-45 connection keep cabling tidy within structured building infrastructure, while the multifrequency RFID support accommodates the mix of card types common in multi-tenancy office environments.
Industrial and Warehouse Access Points
The -40 to 60 degree Celsius operating range and IP54 weatherproofing make this reader appropriate for cold store entries, loading dock doors, and industrial facilities where temperature swings and moisture exposure are routine.
Upgrade Projects with Legacy Cards
Sites transitioning from older 125 kHz systems to newer 13.56 MHz credentials can use this unit as a bridge reader, accepting both formats simultaneously and removing the need for a staged card replacement across all users before the cutover is complete.
Secure Zones Requiring Tamper Detection
The inbuilt tamper switch generates an alert if the reader is removed from its mounting, making this unit suitable for high-security areas such as server rooms, plant rooms, or pharmaceutical storage where physical interference with access hardware must be logged and actioned.
Choosing the Right Model
- Choose this model if: Your site operates a mix of 125 kHz and 13.56 MHz RFID credentials, you have PoE-capable infrastructure already in place, and your access points require an IK08-rated housing that can handle both physical impact and exposure to moisture or temperature extremes.
- Choose a different model if: You need a currently manufactured unit for a new installation with ongoing manufacturer support, warranty coverage, and guaranteed parts availability. As this product is discontinued, a current-generation 2N access reader or an equivalent multifrequency unit from an active product line would be a more supportable long-term choice.
FAQs
- What RFID card types does the 2N Access Unit 2.0 RFID Multifrequency support?
This reader supports both 125 kHz and 13.56 MHz RFID cards and keyfobs. The 125 kHz range covers widely used legacy proximity card formats, while the 13.56 MHz range covers modern contactless smart card standards. The dual-frequency capability allows one reader to handle credentials from both generations without additional hardware at the door.
- Can this reader be powered over a standard network cable?
Yes. The 2N Access Unit 2.0 RFID Multifrequency supports PoE 802.3af (Class 0, up to 12.95 W), meaning a single Cat-5e or better cable provides both the network connection and the power supply. A 12 V DC input is also available as an alternative or supplementary power source if a PoE switch or injector is not part of the installation.
- Is this reader suitable for outdoor or exposed entry point installation?
It carries an IP54 rating, which protects against dust ingress and water splashing from any direction, making it appropriate for covered external entry points, vestibules, and partially exposed mounting positions. The IK08 impact resistance rating and zinc cast housing also provide meaningful resistance to physical interference at public-facing access points.
- What switch outputs does this unit provide for door lock or alarm integration?
The reader includes both a passive switch output (NO/NC contacts rated at 30 V, 1 A AC/DC) and an active switch output (8-12 V DC, max 600 mA). These outputs connect to electric strikes, magnetic locks, or alarm inputs depending on the installation. The inbuilt tamper switch provides an additional output triggered by housing removal or interference.
- Is the 2N Access Unit 2.0 RFID Multifrequency still in production?
No. This product has been confirmed as discontinued by 2N. It is no longer in active production. If you are specifying access readers for a new installation or a staged rollout across multiple doors, confirming current stock availability is strongly recommended before committing to this model in a project specification. Security Wholesalers can advise on current availability.
- What operating temperature range does this reader support?
The 2N Access Unit 2.0 RFID Multifrequency is rated for operation from -40 to 60 degrees Celsius with a relative humidity range of 10-95% (non-condensing). This range makes it technically suitable for cold store entry doors, plant room access points, and outdoor installations in both hot and cold climates where standard readers with narrower temperature ratings would be a risk.
Cabling Considerations
- Cable Type: Cat-5e or better is recommended by the manufacturer for the LAN and PoE connection to this reader.
- Maximum Cable Run: Standard PoE maximum of 100 metres from the PoE switch or injector to the reader applies. Runs approaching or exceeding this distance should be tested for voltage drop before the installation is finalised.
- PoE Considerations: The reader operates on PoE 802.3af Class 0 (up to 12.95 W). Ensure the PoE switch or injector supplying this reader is 802.3af compliant and has sufficient per-port power budget. If a PoE source is not available, a 12 V / 3 A DC supply can be used as an alternative.
- Wiring Tips: The passive switch output (NO/NC, 30 V, 1 A AC/DC) connects directly to compatible electric strike or magnetic lock wiring. The active switch output (8-12 V DC, max 600 mA) is suitable for lower-power lock outputs. The inbuilt tamper switch should be wired into the alarm or access control panel input at installation to ensure tamper events are captured and logged correctly.
