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
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.
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.
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.
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.
