1sna178745r1400 – screening bar cbm5

Why Choose the TE Connectivity 1SNA178745R1400 CBM5 Screening Bar?

The TE Connectivity 1SNA178745R1400, also identified as the CBM5, is a 0.5 mm thick screening bar / shield connector designed for compatible Entrelec SNA series terminal block assemblies. It provides a practical means of maintaining electrical screen continuity through terminal installations, helping support effective shielding in instrumentation, control and signal wiring applications.

The CBM5 is used with compatible terminals including the MTC6 thermocouple terminal block, where the screening bar fits into the lower section of the terminal. In this arrangement it can maintain continuity of the thermocouple cable screen through the terminal block or provide a connection to earth without requiring additional terminal spacing.

Manufactured from treated brass and measuring 0.5 mm in thickness, the 1SNA178745R1400 provides a compact and durable screening connection for professional industrial panel assemblies. Its dedicated design integrates with the Entrelec terminal system while helping maintain organised and space-efficient shield connections.

Reliable Screen Continuity for Signal Wiring

Screened cables are commonly used in instrumentation and control circuits to reduce the effects of electromagnetic interference on low-level electrical signals. Maintaining the cable screen correctly as wiring passes through terminal blocks is therefore important for preserving the intended shielding arrangement.

The CBM5 provides a purpose-designed method of continuing the cable screen through compatible Entrelec terminal blocks. In applications such as MTC6 thermocouple terminals, the screening bar installs in the lower portion of the block and can provide screen continuity or an earth connection without increasing the terminal assembly width.

Typical Applications

• Thermocouple and temperature measurement circuits.
• Industrial instrumentation panels.
• Screened sensor and signal wiring.
• PLC and process-control cabinets.
• Machine automation systems.
• Electrical panels requiring cable shield continuity or earthing.
