Core technical features

The M13 series is rated IP68, meaning it is designed to resist water and dust intrusion in demanding environments. Its threaded locking mechanism is intended to keep electrical connections secure under vibration or movement. Contacts use gold-plated copper, with contact resistance held to ≤10 mΩ to support low-loss signal and power transmission.

These ratings define the operating envelope for the series and are central to its use in compact industrial enclosures, where sealing and reliable contact performance are often decisive factors.

Matching configurations to applications

The M13 family offers several body styles to meet different assembly needs. Engineers should evaluate installation space and cable routing before selecting a variant.

• Straight molded cable end: Suited to conventional cable connections and provides a direct signal path.
• Front-mount panel receptacle: Used mainly for integrating an interface into equipment housings; panel cutout dimensions, internal clearance and sealing-surface fit require close verification.
• Right-angle molded cable end: When internal space is tight or routing is restricted, a right-angle design can reduce bending stress on the cable and help prevent damage.

In each case, the connector must be matched to the housing geometry and the expected movement of the cable during service.

Key checks before ordering

Several details should be confirmed against the actual equipment design before a connector is specified, to avoid installation conflicts.

1. Pinout: The M13 series covers 2-, 3-, 4-, 2+3 hybrid, 5-, 6-, 7- and 8-pin layouts. The specific contact assignment must match the equipment requirements.
2. Installation environment: For front-mount panel installation, confirm the mounting direction and ensure there is enough internal clearance for the plug and rear cable.
3. Cable specification: Verify that the cable outer diameter falls within the Ø3.0 mm to Ø7.5 mm range so the connector’s sealing performance can be fully realized.

Electrical ratings also merit attention when pin count changes. Different pinouts may use different contact arrangements, which can affect voltage and current limits.
