3M 37104-2124-000 FL 4-Pole Low Current IDC Connector, Green, 0.3-0.56 mm², 20-22 AWG, 60 V, 1 A

This 4-pole insulation displacement connector (IDC) offers a solderless wire-to-wire solution for low current applications. Unlike traditional connectors that require stripping and soldering, the 37104-2124-000 FL uses IDC technology to terminate flexible or solid conductors quickly and reliably. The green polypropylene housing is free-hanging and compact, making it suitable for tight spaces and field installations.

Highlights

• 4-pole IDC connector for wire-to-wire connections
• Accepts flexible and solid wires from 0.3 to 0.56 mm² (20-22 AWG)
• Free-hanging inline design with green polypropylene housing
• Rated for up to 60 V and 1 A
• Operating temperature range: -40°C to +85°C

In daily use

This connector simplifies low-voltage wiring tasks such as sensor connections, control circuits, and signal lines. The insulation displacement contacts cut through the wire insulation when pressed, creating a gas-tight connection that resists vibration and corrosion. The compact size and free-hanging design allow installation in tight spaces without additional mounting hardware.
