Long-range Serial Links – With 9-pin, 10m cable length
Standard 9-pin DB9 wiring runs across 990 cm of cable without connectors and 1000 cm including connectors, carrying RS-232 signalling for serial peripherals. The length is suited to link host computers with peripherals without intermediate extensions.
Place modems, label printers and handhelds further from a PC without repeaters. Fewer junctions reduce connection points and simplify routing.
Secure Attachment for Vibration-Prone Environments – With screw-on DB9 connectors
Screw-on fastening clamps male and female DB9 plugs to prevent loosening under movement or vibration. Plug and socket dimensions keep the connector footprint compact for panel and rack use.
Maintain reliable connections in workshops and transport situations where unsecured plugs can work loose. Secure fastenings reduce intermittent faults and downtime.
Broad Compatibility with Legacy Kit – Thanks to standard RS-232 DB9 wiring
Male-to-female DB9 format matches common RS-232 serial ports used by modems, UPS units, ISDN terminal adapters, digital cameras, labelers, handhelds and PDAs. No special adapters are required for matching DB9 ports.
Connect a wide range of legacy serial devices directly to host equipment. Straightforward compatibility means fewer compatibility checks during installation.
