Industrial PoE Switch 4-Port 250m Extended 30W UPoE DIN-Rail

Industrial PoE Switch 4-Port 250m Extended 30W UPoE DIN-Rail

Product Overview:

The LNK-GYT420P Series Industrial Long-Range PoE Switch delivers 250m extended distance connectivity with 4×10/100BASE-T PoE+ ports and 2×100M uplink ports, specifically designed for demanding industrial surveillance and networking applications.

Key Features & Benefits:

✅ Extended-Range PoE+ Power Delivery

• 4× PoE+ ports (IEEE 802.3af/at compliant) transmit both power and data up to 250 meters - ideal for large-area surveillance deployments

• 30W max per port supports power-hungry devices like PTZ cameras, thermal imagers, and industrial sensors

✅ Industrial-Grade Reliability

• Enhanced surge protection (6kV) and static electricity shielding for harsh environments

• Wide operating temperature range (-40°C to 75°C) suitable for outdoor cabinet installations

• Reinforced metal housing withstands vibration and EMI interference

✅ Advanced Network Management

• One-key VLAN mode simplifies network segmentation for video surveillance systems

• QoS priority tagging ensures smooth transmission of critical surveillance footage

• Storm control prevents network congestion and malicious attacks

✅ Optimized for Security Applications

• Non-blocking switching architecture delivers wire-speed throughput for uninterrupted video streams

• 250m extended range eliminates the need for additional repeaters in large-scale deployments

• Plug-and-play operation requires minimal configuration

Product Features:

1. Extended-Range PoE+ Connectivity (250m)

• 250m Long-Distance Transmission: Ideal for large-area surveillance and outdoor wireless AP deployments.

• 10Mbps at 250m: Ensures stable connectivity for IP cameras even at maximum range.

• 4×10/100BASE-T PoE+ Ports: Deliver IEEE 802.3af (15.4W) & 802.3at (30W) power to PTZ cameras, industrial sensors, and VoIP phones.

2. Industrial-Grade Reliability

• 6KV Lightning & Surge Protection: Safeguards against power surges in harsh environments.

• Redundant Dual Power Inputs (12~48VDC): Ensures 24/7 uptime for critical applications.

• Wide Temperature Range (-40°C to 80°C): Operates reliably in extreme outdoor/industrial conditions.

3. Flexible Deployment & Installation

• DIN-Rail or Wall-Mountable: Compact design for control cabinets, traffic cabinets, or tight spaces.

• Auto MDI/MDIX & Auto-Negotiation: Simplifies installation with plug-and-play connectivity.

• 802.3x Flow Control: Prevents data loss in high-traffic surveillance networks.

4. Optimized for Surveillance & IoT

• Full/Half-Duplex Mode Support: Maximizes bandwidth efficiency for real-time video streaming.

• 2×100M Uplink Ports: Enable network expansion or fiber connectivity via media converters.

• Industrial Metal Housing: Resists EMI interference, dust, and vibration.

Application Scenarios

1. Industrial Surveillance Systems

• Powers and connects long-range IP cameras (250m) in factory complexes, oil refineries, and mining sites

• Enables extended-distance video transmission for perimeter security monitoring

• Withstands harsh industrial environments (-40°C to 80°C) with 6kV surge protection

2. Transportation Infrastructure

• Ideal for highway/tunnel surveillance systems requiring 250m PoE reach

• Provides power+data to roadside traffic cameras and variable message signs

• DIN-rail mounting suits control cabinet installations in transportation hubs

3. Smart City Deployments

• Connects distributed IoT devices across urban surveillance networks

• Supports outdoor wireless APs in municipal WiFi projects

• Redundant power inputs ensure reliability for critical city infrastructure

4. Agricultural Monitoring

• Extends PoE networks across large farms and greenhouses

• Powers weather stations, soil sensors, and irrigation controllers

• Industrial-grade construction resists humidity and temperature fluctuations

5. Energy Sector Applications

• Reliable connectivity for remote substation monitoring equipment

• 30W PoE+ ports support pan-tilt-zoom thermal cameras

• Metal housing provides EMI protection near high-voltage equipment

Technical Advantages Summary:

• Extended 250m PoE transmission eliminates intermediate power sources

• Dual power inputs (12-48VDC) ensure continuous operation

• 802.3af/at compliance powers both standard and high-power devices

• Industrial certifications meet IEC 61850-3 for critical infrastructure
