The ConnexLink™ Wireless Radio 900 MHz Transceiver offers a simple and powerful solution for wireless serial data communication in industrial weighing applications. Whether you're linking scales, indicators, PLCs, or other electronics, this radio module provides secure and robust communication across vast distances—up to 20 miles line-of-sight.
Engineered for reliability, it supports both point-to-point and point-to-multipoint setups and operates in the 902–928 MHz frequency band using frequency-hopping spread spectrum (FHSS) modulation. The transceiver is housed in a durable, industrial-grade enclosure designed to withstand extreme temperatures and environments, with built-in mounting flanges for easy installation.
Available in Standard (RS-232) and Pro (RS-485) versions, the ConnexLink series ensures compatibility with most industrial control systems. DES-level encryption and 32 configurable channels offer added data security and reduced interference.
