1SNA205567R0600 – PCMS-21

Why Choose the TE Connectivity PCMS-21 21-Pole Grey Comb Jumper?

The TE Connectivity PCMS-21, part number 1SNA205567R0600, is a 21-pole grey comb jumper designed for electrically cross-connecting compatible Entrelec terminal blocks. This terminal block accessory provides an efficient way to distribute a common electrical potential across twenty-one adjacent terminal positions in industrial control panels, automation equipment and electrical distribution assemblies.

The PCMS-21 replaces multiple individual jumper wires with a single purpose-designed cross-connector, helping simplify panel assembly and maintain neat, organised terminal strips. Its 21-pole configuration is particularly useful where a common connection needs to be distributed across a large group of compatible terminals.

Rated at 16 A, the PCMS-21 combines a high pole count with compact comb-jumper construction. Its grey colour provides straightforward visual identification, while the established TE Connectivity / Entrelec design makes it suitable for new panel construction, OEM equipment and maintenance of compatible terminal systems.

Reliable Terminal Cross-Connections for Industrial Panels

Comb jumpers provide an efficient and repeatable method of distributing a common electrical potential across adjacent compatible terminal blocks. By using a dedicated cross-connector instead of multiple individual jumper wires, panel builders can reduce wiring operations while producing a cleaner and easier-to-service terminal assembly.

With 21 interconnected positions and a 16 A rating, the TE Connectivity PCMS-21 is particularly suited to larger common-potential groups. Its purpose-designed construction makes it a practical accessory for compatible Entrelec terminal systems used throughout industrial automation, machinery and electrical control equipment.

Typical Applications

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