FL Connector 3M 37104-3122-000 — Flexible insulation-piercing connector for conductors 0.14–0.25 mm²

3M FL Connector 37104-3122-000 is a flexible insulation‑piercing connector for quick electrical tapping or splicing of conductors with cross-sections from 0.14 to 0.25 mm². The connector makes reliable contact without the need to strip insulation, delivering a compact, space‑saving solution suitable for control panels, lighting circuits, automotive wiring and sensor lines.

Advantages

The FL connector provides fast, repeatable connections by piercing insulation and clamping the conductor securely, reducing installation time and the risk of conductor damage. Its compact design supports tight mounting spaces and consistent electrical contact across the supported conductor range. The product is supplied as a single Miniclamp unit with gel for environmental protection.

Suitable for

• Tapping or splicing small single‑core conductors (0.14–0.25 mm²)
• Control panels and terminal blocks where space is limited
• Lighting circuits and sensor wiring
• Automotive low‑voltage wiring and electronic harnesses

How to use

Position the insulated conductor in the connector slot, close the connector to pierce the insulation and establish contact, then secure the connector according to the manufacturer's closing method. No conductor stripping is required. Verify the electrical connection after installation and ensure the gel seals the contact area to protect against moisture and contamination.

Recommendations

Use the connector only with conductors within the specified 0.14–0.25 mm² range and follow applicable electrical safety practices. For permanent or high‑current runs, confirm suitability for the specific application and operating environment before installation.
