Configured for signal distribution in SENG control network architectures, the YOKOGAWA YCB146 (YCB146 T-shaped Control Bus Connector) provides direct physical execution of bus branching and signal propagation.

Suffix Breakdown & Model Matrix

The YCB146 is a fixed-design T-shaped connector component. No configurable suffixes or variants exist for this specific model number; the hardware is standardized for 10BASE-2 coaxial bus topology within the SENG framework.

Hardware Specifications

Channel-to-Channel Isolation and Bus Signal Integrity

The YCB146 serves as a physical junction node, facilitating the extraction of control signals from the primary backbone to local drop segments. In Yokogawa control network environments, the T-connector maintains the characteristic impedance of the transmission line to prevent signal reflections. Maintaining low contact resistance at the BNC interface is required to preserve the signal-to-noise ratio within the 10 Mbps data stream, ensuring consistent communication latency across all interconnected SENG nodes.

Frequently Asked Questions

Q: Does the installation of the YCB146 T-connector introduce signal attenuation?

A: Yes. Every connection point in a 10BASE-2 network introduces a minor insertion loss. Excessive use of T-connectors on a single cable segment beyond the specified design limits of the SENG network may lead to signal degradation and packet transmission errors.

Q: Is this connector shielded against electromagnetic interference?

A: The housing is constructed to maintain the continuity of the coaxial shield. Proper seating of the BNC connectors ensures that the outer shell remains at ground potential, protecting the central signal conductor from external electrical noise.

Field Installation Guidelines

1. BNC Engagement: Insert the male BNC connector of the drop cable into the perpendicular port of the YCB146. Rotate the locking collar clockwise until a distinct click is felt, ensuring the connection is mechanically locked.
2. Bus Continuity: Ensure the main backbone coaxial cable is securely connected to the two in-line ports of the T-connector. Avoid sharp bends at the connection point to prevent physical stress on the BNC center pin.
3. Impedance Matching: Verify that the total length of the bus segment remains within the specified limits. Terminate the far ends of the bus with the appropriate resistance to avoid standing waves on the coaxial line.
4. Environment: Secure the cabling to minimize mechanical vibration, which can lead to intermittent contact failure in the BNC interface over extended operational cycles.
