Altronix PACE1KL24S 10Base-T1L/ET Media Adapter with 24V Power over Single-Pair Ethernet

Overview

The Altronix PACE1KL24S is a 10Base-T1L Single-Pair Ethernet (SPE) media adapter that extends 10Mbps IP data and 20W of device power over a single twisted pair of wire to distances up to 1,000 meters (3,280 ft.) — roughly three times the reach of standard 100BASE-TX and nearly seven times the 150m ceiling of PoE-over-UTP. If you're connecting IP endpoints in sub-stations, parking structures, perimeter fencing, or industrial yards where running conduit or deploying repeaters has always been the cost driver, the PACE1KL24S changes the math. It implements the IEEE 802.3cg (10BASE-T1L) standard, which means it is interoperable with any conforming 802.3cg device at the far end — you're not locked into a proprietary ecosystem.

Key Features

• 1,000m (3,280 ft.) Single-Pair Reach: Where standard PoE tops out at 100m and long-reach solutions rarely exceed 300–500m without repeaters, the PACE1KL24S natively runs 10Mbps data and power the entire kilometer on a single pair. That directly eliminates intermediate powered repeaters, fiber media converters, or conduit pulls that typically inflate remote-endpoint budgets by thousands of dollars per run.
• 20W Power Output: With 20W available at the remote device, you can confidently power full-featured IP cameras including those drawing PoE+ levels — IR illuminators, pan-tilt mechanisms, and local edge-storage cameras all typically fall within this envelope. No separate power feed at the camera end means fewer enclosures, less wiring, and fewer points of failure in the field.
• IEEE 802.3cg / 10BASE-T1L Protocol Compliance: Adhering to the published IEEE 802.3cg standard rather than a proprietary long-reach scheme protects your investment. As vendors add native 10BASE-T1L ports to field devices — a trend already underway in industrial IoT and smart infrastructure — this adapter gives your existing infrastructure a standards-forward on-ramp without forklift upgrades.
• –40°C to +75°C Operating Range: The PACE1KL24S is rated for both extreme cold and elevated heat — a range that covers unheated rooftop cabinets in northern climates and sun-baked outdoor enclosures in the southwest equally. Most competing long-reach adapters narrow to 0°C on the cold end; this unit doesn't require enclosure heaters in harsh winter deployments.
• UL/cUL and CE Agency Listings: UL/cUL listing supports integration into UL 294 access control and UL 2050 central-station-monitored systems where listed components are a specification requirement. CE marking covers European deployments. If your project spec sheet demands listed hardware, this unit qualifies.
