PLC Solutions: High-Performance Cables and Connectors

Ensuring programmable logic controllers (PLCs) function properly—with minimized latency, optimized efficiency, exceptional reliability and strengthened resistance to cybersecurity threats—requires specialized electronic components. Molex interconnect, hardware and software products provide durable and high-performance solutions to help ensure the reliable operation of PLCs in harsh environments.

Enhancing Industrial Automation with PLC Connectivity

PLCs must do more than operate reliably in harsh environments. They must minimize latency and improve signal integrity (SI) to support seamless automated manufacturing. Communication with devices on the production line must be stable and reliable to maximize uptime. PLCs need to optimize power supply connectivity to ensure efficient operation. They must also provide security against cyberattacks and other threats that can impact smart factory performance.

Specialized processing and connectivity solutions designed for the industrial market can help designers build effective and efficient PLCs. High-speed I/O connectors help reduce latency and improve system performance, enhancing quality and safety. Low-loss power connections and power supply module components help maximize efficiency, reduce costs and improve thermal management. Safety and security functions integrated with the PLC help guard against cyberthreats.

Industrial interconnect and automation solutions from Molex help ensure reliable and high-performance PLC operation. Internal backplane and board-to-board connectors minimize the PCB footprint while providing exceptional SI and ample bandwidth to reduce latency. Space-efficient power connectors reduce power consumption to maximize power efficiency. Rugged, sealed external connectors with IP67 or IP68 ratings withstand harsh conditions and deliver consistent performance. Network Interface Cards and SDKs are designed for resistance to cyberthreats and help optimize industrial networks for high-demand, high-performance stability and reliability.
