Overview
The Siemens 6GK1905-0FA00 is a rugged 7/8″ 5-pin male connector plug built for PROFIBUS industrial networks. Engineered for ET 200 and ET 200ECO distributed I/O systems, this BFOC (Binder ECOFAST) circular connector delivers field-assembly capability with an integral axial cable outlet. The pin insert configuration allows technicians to prepare and terminate SIMATIC NET cables on-site, reducing integration time and supporting modular automation deployments. Sold in a 5-piece pack.
Key Features
- BFOC circular connector design for ET 200 remote I/O and PROFIBUS applications
- Axial cable outlet (180°) enables field-assembly of standardized PROFIBUS cables
- Compact 7/8″ form factor fits space-constrained terminal box installations
- Pin insert contacts rated IP65/IP67 when mated; gland nut strain relief
- Rated for -40 to +80°C ambient operation; suitable for cold storage and outdoor enclosures
- Manufactured in Germany to Siemens quality standards
Technical Specifications
This connector is compatible with 1.5 mm² fine-strand and solid-core conductors. When assembled as a complete connector pair (mated with female 6GK1905-0FB00), the assembly achieves IP65/IP67 environmental protection. Contact material is copper alloy, and the housing is metallic with integral locking gland nut. Mounting is through a 7/8″ circular panel cutout or M20 threaded port.
Typical Applications
- ET 200S, ET 200M, and ET 200ECO distributed I/O station connections
- PROFIBUS-DP segment cabling and field node termination
- Industrial automation systems requiring modular I/O architecture
- Assembly lines, packaging machinery, and process control networks
- Outdoor cabinets and temperature-extreme environments (-40 to +80°C)
Compatibility & Replacements
The 6GK1905-0FA00 is the male pin insert variant; pair with Siemens 6GK1905-0FB00 (female socket insert) to form complete ET 200 connection plugs. This is standard original equipment for Siemens SIMATIC NET and ET 200 configurations. Replacement of worn or damaged connectors restores PROFIBUS communication integrity without requiring cable replacement or panel re-drilling.
