Middletown, PA – Phoenix Contact released 7/8-in. Mini SAC cordsets , the first connectorized cables to receive compliance registration in accordance with 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 test cases, based on IEC 61158-2:2003 standard, include impedance, capacitive unbalance, connector pin-outs, and attenuation.
The 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, it can be used as open wiring without a metallic sheath or armor between the cable tray and equipment for up to 15 meters. It is not necessary to install conduit to every device.
Phoenix Contact offers two other connectors for Foundation Fieldbus applications: a junction tee to extend 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.
These industrial network connectors feature stainless-steel coupling nuts and knurled screws to withstand heavy impact and resist corrosion in harsh environments. IP67-rated, RoHS-compliant, and sunlight-resistant, connectors meet IEC and ISA standards for H1 physical layer.
