Field Connection with Lever, now for 2.5 mm² too

The powerful MCS MIDI allows convenient, tool-free wiring of conductors with cross-sections up to 2.5 mm².

The MCS MIDI single-conductor female connector will soon be available with a lever for conductor cross-sections from 0.14 to 2.5 mm² (26 to 12 AWG) and 5 mm pin spacing. It boasts an ideal combination of high performance, compact design and convenient lever operation, providing the missing link in the connector family of WAGO’s MULTI CONNECTION SYSTEM (MCS).

The Benefits for You

  • Tool-free manual wiring thanks to lever operation

  • Push-in CAGE CLAMP® termination

  • Powerful pluggable PCB connector for up to 16 A

  • Compact design for conductor cross-sections up to 2.5 mm²

Intuitive Tool-Free Operation

Lever operation makes manual wiring easy. The lever requires no tools and allows intuitive operation. Thanks to CAGE CLAMP®, solid conductors and fine-stranded conductors with ferrules can be connected by simply pushing them into the unit. The connector has a current carrying capacity of up to 16 A and an overall height of just 11.5 mm. It can be used in drive controllers, converters and power supplies, for example.

This pluggable PCB connector is available in two versions: MCS MIDI Classic and MCS MIDI with 100 % protection against mismating. For maximum safety for field connections, the MIDI pluggable connection systems are available with a center or side locking lever upon request. The pluggable connection system allows optional direct marking.
