Why Choose the TE Connectivity PCMS-20-BL 20-Pole Blue Comb Jumper?

The TE Connectivity PCMS-20-BL, part number 1SNA205565R0400, is a 20-pole blue insulated comb jumper designed for electrically cross-connecting compatible Entrelec terminal blocks. Also listed under the legacy description (INT) PCMS J BAR BLUE, this terminal accessory provides an efficient method of distributing a common electrical potential across a large group of adjacent terminal positions.

The PCMS comb-jumper system is designed to electrically connect between 2 and 22 compatible terminal blocks, with this specific PCMS-20-BL version providing 20 interconnected poles. Its purpose-designed construction eliminates the need to install numerous individual jumper wires, helping simplify panel assembly and maintain an organised terminal strip.

The PCMS-20-BL features blue UL94 V-0 insulation and a 5.08 mm pitch. Its combination of high pole count, compact construction and dedicated terminal-block compatibility makes it particularly useful in industrial automation, control-panel and interface wiring applications requiring repeated common-potential connections.

Key Advantages

• Provides a convenient 20-pole cross-connection for compatible terminal blocks.

Reliable Terminal Cross-Connections for Industrial Panels

Comb jumpers provide a controlled and efficient way to distribute a common electrical potential across multiple compatible terminal blocks. Using a dedicated cross-connector instead of individual jumper wires reduces the number of separate wiring operations and helps produce a cleaner, easier-to-service terminal assembly.

With 20 interconnected positions, the TE Connectivity PCMS-20-BL is particularly suited to larger common-potential groups. Its 5.08 mm pitch and blue insulated construction provide a purpose-designed solution for compatible Entrelec terminal systems used in automation, machinery and industrial electrical equipment.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Terminal block common-potential distribution.
• Interface relay and control wiring assemblies.
• Machine building and OEM electrical systems.
• Switchgear and electrical distribution equipment.
