3M hh Schwachstromverbinder 37303-2165-000 FL flexible 0.3–0.56 mm² 3‑pole low‑current connector

The 3M hh Schwachstromverbinder 37303-2165-000 FL is a three‑pole low‑current connector designed for flexible conductors with cross‑sections from 0.3 to 0.56 mm². Intended for signal wiring and small power circuits, this compact connector offers reliable electrical contact and a space‑saving form factor suitable for panel assemblies, device internals and wiring harnesses where precise, low‑current terminations are required.

Advantages

This 3‑pole low‑current connector provides secure contact for small conductors and consistent electrical performance in low‑current applications. Its compact design simplifies installation in confined spaces and supports flexible conductors within the specified cross‑section range. The connector is designed for durability in routine electrical assemblies and helps maintain signal integrity in control and communication circuits.

Suitable for

• Signal wiring in control panels and instrumentation
• Internal device wiring where space is limited
• Light current harness assemblies and interconnections
• Prototyping and small-scale production of electronic equipment

Key specifications

• Poles: 3
• Conductor type: flexible (stranded) conductors
• Supported conductor cross‑section: 0.3–0.56 mm²
• Application: low‑current / weak‑current circuits and signal lines
• Form factor: compact, panel/device compatible connector

How to use

Strip the insulation from the flexible conductor to the length recommended by the connector manufacturer, insert the conductor into the appropriate pole until it seats firmly, and secure the connection according to the mounting or termination method provided. Verify that each conductor is fully engaged and that no stray strands are exposed. After assembly, perform continuity and insulation checks as required by the application to confirm correct wiring and reliable contact.

Recommendations

Use conductors within the specified 0.3–0.56 mm² range and follow standard low‑current wiring practices. Avoid exceeding the connector's intended current and voltage limits, route wiring to minimise mechanical stress, and apply appropriate strain relief in harnesses or panel assemblies to preserve contact integrity over time.
