Spherag ATX Sensor Hub – 4-Channel 4–20 mA Signal Distribution
The Spherag ATX Sensor Hub is a compact, rugged signal-distribution unit designed to split a single upstream data or power cable into four independent 4–20 mA sensor outputs. Each output terminates in a waterproof circular connector with a threaded locking collar and integrated cable gland, making field wiring fast and secure without additional junction boxes. The central hub body is moulded in black engineering-grade polymer and accommodates a top-entry cable, keeping the installation profile low inside control panels, greenhouse ducts, or poolside enclosures.
The 4–20 mA current-loop standard is the dominant signalling protocol for sensors measuring flow, pressure, temperature, pH, ORP, and conductivity in pool plant rooms and irrigation systems. By fanning one controller channel into four independent loops, the ATX hub reduces wiring runs, eliminates separate splitter modules, and maintains loop accuracy regardless of cable length. The cable markings visible on the pigtails reference 2464 AWG 20 A and 300 V rated wire, confirming the assembly is built for continuous outdoor or wet-environment duty.
Specificații

Compatibilitate
Compatible with any sensor or controller using the industry-standard 4–20 mA current-loop protocol, including pool water-quality transmitters, greenhouse climate sensors, irrigation pressure transducers, and flow meters. Output connectors follow the Weipu waterproof circular connector format; mating plugs must match this connector series. Not intended for analogue voltage (0–10 V) signal circuits without verified loop converter.
