Plug in this D-sub connector from Phoenix Contact to achieve secure connections in Modbus, RS-232, RS-422 and RS-485 systems. It has an inbuilt reversible connection block, which makes it easy to change the pin assignments without needing to assemble a new cable or rewire the entire connector. Compact dimensions of 78.7 (L) x 16 (W) x 49.5mm (D) mean it fits into most standard-size enclosures.
A high mean time between failures of up to 6,706 years means you can bank on this device for long-term performance. Metal-plated ABS casing shields it from impact and provides electrical insulation. Thanks to an operating temperature range between -20°C and +75°C, this is an ideal choice for use in harsh environments. Connectors like this one are commonly used to establish serial and parallel port connections in telecommunications networks, computer systems and industrial equipment.

• Knurled screws for easy tightening by hand
• Copper-alloy contacts for efficient signal transfer
• IP20 rating means it's touch-proof and resistant to objects bigger than 12.5mm
• Protected against harmful EMI and ESD to ensure reliable performance
