MIDDLETOWN, Pa. ‚– Phoenix Contact‚’s 7/8-inch MINI SAC cordsets are the first connectorized cables to receive official compliance registration in accordance with the Fieldbus Foundation‚’s FF-844 requirements for H1 Type A cable.
The H1 Cable Test Specification (Document FF-844) is designed for manufacturers developing cables for FOUNDATION Fieldbus H1 (31.25 kbit/s) installations. The specification test cases, based upon the IEC 61158-2:2003 standard, include (but are not limited to) impedance, capacitive unbalance, connector pin-outs, and attenuation.
Phoenix Contact‚’s Type A overmolded cordset for H1 physical media is constructed of instrumentation tray cable (ITC)/power-limited tray cable (PLTC-ER). Under the National Electric Code (NEC), this cable can be used as open wiring without a metallic sheath or armor between the cable tray and equipment for up to 15 meters. Because it is not necessary to install conduit to every individual device, ITC reduces the installation time and cost.
In addition to the cordsets, Phoenix Contact also offers two other connectors for FOUNDATION Fieldbus applications: a junction tee, which extends connection from a device to the main trunk line, and a 4-position male terminator that attaches to the end of each segment along the trunk.
All three connectors feature stainless steel coupling nuts and knurled screws, allowing them to withstand heavy impact and resist corrosion in harsh industrial environments. The connectors are IP67-rated, RoHS-compliant and sunlight-resistant. They meet IEC and ISA standards for H1 physical layer
