Mechanical Construction and Interface Details
This cord set features a robust overmolded strain relief at both connector ends. The metal D-sub housings provide excellent electromagnetic interference protection. Each connector includes locking screws for vibration-resistant mating. The cable uses tinned copper drain wire for effective grounding. This construction ensures reliable data transfer in electrically noisy environments.
Electrical Performance and Signal Integrity
The cable maintains characteristic impedance of 120 ohms for RS-422/RS-485 protocols. Its braided shield reduces common-mode noise by up to 40 decibels. The PVC insulation prevents signal attenuation over the full 3.5-meter length. Each conductor terminates in a machined pin contact for low resistance. This design supports high-speed communication up to 1 Mbps.
Installation and Compatibility
You can install this cord set without special tools or soldering. The connector keying prevents incorrect insertion into compatible ports. It directly interfaces with Modicon M340 and M580 automation platforms. The 26 AWG conductors allow flexible routing in control cabinets. This cord set also works with third-party devices using standard D-sub pinouts.
Environmental and Durability Ratings
The cord set withstands industrial oils and coolants commonly found in factory floors. Its temperature range covers both cold storage and high-heat zones. The nickel-plated connectors resist corrosion in humid conditions. Each cable undergoes 5000-cycle flex testing for long service life. The PVC jacket also provides flame retardancy per UL 94 V-2 standards.
Packaging and Physical Dimensions
Each unit comes in a sealed anti-static bag to prevent ESD damage. The complete assembly weighs approximately 0.25 kilograms. Its compact design occupies minimal space inside wire ducts. The 3.5-meter length offers ample reach for most panel layouts. The cable remains flexible even at low temperatures for easy routing.
