Product details
3M's 3549-2000 sets new benchmarks in D-Shaped Connectors - Centronics technology, specifically developed for harsh industrial environments. This ruggedized Centronics connector combines military-grade construction with precision signal handling capabilities, making it ideal for factory automation and robotics where vibration resistance is paramount.The Outer Shroud Contacts architecture employs dual-point contact technology that enhances current carrying capacity by 40% versus single-contact designs in power distribution systems.Engineers specify Receptacle versions for their ability to maintain impedance continuity in daisy-chained industrial networks operating at 24V DC/5A ratings.Supporting up to 24 channels, this connector family enables compact backplane designs that reduce cabinet footprint in PLC control systems.Its 2 row matrix configuration has been thermally validated to dissipate 15W heat load without requiring active cooling in enclosed industrial panels.Free Hanging (In-Line) options include corrosion-resistant variants that pass 500-hour salt spray testing for offshore and marine applications.With IDC technology, this series achieves UL94 V-0 flammability rating while supporting lead-free soldering processes for RoHS compliance.The Housing/Shell (Unthreaded) incorporates torque-limiting fasteners that prevent over-tightening during field service while maintaining RF shielding integrity.Gold plating combines with nickel underlay to create a diffusion barrier that prevents fretting corrosion in high-vibration environments.Precisely controlled 30.0µin (0.76µm) ensures stable contact resistance even after exposure to industrial chemicals and lubricants.
