1sna036904r1200 – la500/subd25f/omn20/648

Why Choose the TE Connectivity 1SNA036904R1200 LA500/SUBD25F/OMN20/648 Interfast Cable?

The TE Connectivity 1SNA036904R1200, also identified as LA500/SUBD25F/OMN20/648, is a 5 m prewired Interfast connection cable designed to provide reliable signal connections between compatible PLC equipment and Entrelec modular interface systems. It combines a 25-pole female Sub-D connector with a 20-point Omniconnect interface connector, providing a practical preassembled solution for industrial automation wiring.

Part of the established Entrelec Interfast range, this cable helps reduce point-to-point wiring requirements inside control cabinets. Factory-prewired conductors and dedicated connectors simplify installation, minimise wiring errors and support faster commissioning when connecting compatible PLC I/O equipment to Interfast interface modules.

The LA500 version provides a 5 m cable length and uses 0.22 mm² / 24 AWG conductors. The specified cable characteristics are approximately 80 Ω/km resistance and 120 nF/km capacitance, making the assembly suitable for industrial signal and I/O interconnection applications.

Efficient Prewired Connectivity for PLC Systems

Prewired interface cables provide an efficient alternative to conventional individual conductor wiring between PLC I/O equipment and terminal interfaces. By combining predetermined connections into a factory-assembled cable, they can significantly reduce installation effort while improving consistency and helping prevent wiring mistakes in complex automation cabinets.

The LA500/SUBD25F/OMN20/648 connects a 25-pole female Sub-D interface to a 20-point Omniconnect connection. Its 5 m length provides additional routing flexibility for installations where the PLC and interface module are positioned farther apart within an enclosure or automation system.

Typical Applications

• PLC input and output wiring systems.
• Industrial automation control panels.
• Entrelec Interfast interface assemblies.
• Machine control and OEM automation equipment.
• Process control and instrumentation systems.
• Factory automation and production machinery.
• Prewired signal distribution between PLCs and interface modules.
