M8 Connectors – The solution for sensing, data, and low-power applications

M8 connectors are the go-to choice when it comes to reliable connections in tight spaces. Thanks to their compact design, they’re ideal for use in sensing and actuation applications, as well as in environments with limited installation space—such as miniature sensors, small machines, or control cabinets.
Built with robust materials and rated up to IP67, these connectors ensure dependable performance even under harsh conditions involving dust, moisture, or mechanical stress.

M8 connectors are available in both straight and angled versions. Depending on the application, they come in 2- to 8-pin configurations—offered as field-attachable, overmolded, or panel-mount versions. For simplified maintenance and fast diagnostics right at the connector, models with integrated LED status indicators are also available.

For direct PCB mounting, solder versions are offered in both THR (Through Hole Reflow) and SMD (Surface Mount Device) formats. Connectors can be supplied in bulk or tape-and-reel packaging, supporting efficient processing in pick-and-place lines and seamless integration into modern manufacturing workflows.

Typical application areas:

  • Conveying and Packaging Technology: Reliable signal transmission and status monitoring right at the connection point — with optional integrated LED indicators.
  • Building and Security Systems: Compact solutions for control and monitoring systems.
  • Test and Inspection Equipment: Flexible, temporary connections with immediate visual signal status.
  • Environmental and Solar Technology: Resistant to dust, moisture, and temperature fluctuations.

M8 Connector codings:

  • A-coded: Commonly used for sensor/actuator connections, DC power, and signal transmission.
  • B-coded: Primarily used for fieldbus systems such as Profibus.
  • D-coded: 4-pin, optimized for Ethernet data transmission up to 100 Mbit/s — ideal for compact Industrial Ethernet applications.
  • P-coded: Designed for EtherCAT P, which combines high-speed EtherCAT communication with 24 V power supply in a single connector.
