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.

The AWK-4252A Series is compliant with the IEC 62443-4-2 and IEC 62443-4-1 Industrial Cybersecurity certifications, which cover both product security and secure development life-cycle requirements, helping our customers meet the compliance requirements of secure industrial network design.
