Introduction

The AWK-4252A Series 3-in-1 industrial wireless AP/bridge/client is designed to meet the growing need for faster data transmission speeds through IEEE 802.11ac technology for aggregated data rates of up to 1.267 Gbps. The AWK-4252A is compliant with industrial standards and approvals covering operating temperature, power input voltage, surge, ESD, and vibration. The two redundant DC power inputs increase the reliability of the power supply, and the AWK-4252A can be powered via PoE to facilitate flexible deployment. The AWK-4252A can operate concurrently on both the 2.4 and 5 GHz bands and is backwards-compatible with existing 802.11a/b/g/n deployments to future-proof your wireless investments.

IEC 62443-4-2 Security Level 1 Certified

The US and UN models of the series are IEC 62443-4-2 Security Level 1 certified (FR_Cyber10095) helping our customers meet the compliance requirements of secure industrial network design.

Advanced 802.11ac Industrial Wireless Solution

802.11a/b/g/n/ac compliant AP/bridge/client for flexible deployment
DFS channel support allows a wider range of 5 GHz channel selection to avoid interference from existing wireless infrastructure

Advanced Wireless Technology

Seamless roaming with client-based Turbo Roaming The Turbo Roaming recovery time indicated herein is an average of test results documented, in optimized conditions, across APs configured with interference-free 20-MHz RF channels, WPA2-PSK security, and default Turbo Roaming parameters. The clients are configured with 3-channel roaming at 100 Kbps traffic load. Other conditions may also impact roaming performance. For more information about Turbo Roaming parameter settings, refer to the product manual. for < 150 ms roaming recovery time between APs (Client Mode)

Industrial Ruggedness

-40 to 75°C wide operating temperature for smooth wireless communication in harsh environments
Enhanced antenna port isolation protection designed to withstand up to 30 kV ESD and 6 kV surge protection
