HONEYWELL 2MLC-E301 SmartLine Extension Cable – SmartLine Temperature Transmitter Series
In demanding industrial environments, a failed or missing extension cable between a temperature transmitter and its remote display or configuration tool can bring an entire process loop to a standstill. Operators lose real-time temperature visibility, maintenance teams cannot perform HART communication or configuration, and unplanned downtime cascades across the production line. The HONEYWELL 2MLC-E301 SmartLine Extension Cable is the purpose-engineered solution that eliminates this risk — providing a secure, noise-resistant electrical connection between the STT850 SmartLine Temperature Transmitter and its local operator interface or handheld communicator.
The 2MLC-E301 is a factory-specified accessory within Honeywell’s SmartLine transmitter ecosystem — one of the most widely deployed intelligent transmitter platforms in global process industries. Designed to meet the mechanical and electrical requirements of the STT850 series, this extension cable ensures signal integrity across the full operating temperature range of the transmitter, making it an indispensable component for installations where the display module must be remotely mounted or repositioned for operator accessibility. Its adoption spans refineries, chemical plants, power generation facilities, and pharmaceutical manufacturing sites across six continents.
