An M23 5 pin self-locking waterproof connector project begins with understanding the complete interface, not simply with selecting a contact count. In e-mobility and industrial equipment, the connection point may need to fit a defined cable assembly, a practical mating process and the physical layout of the equipment. These details should be organized before a catalogue configuration is evaluated.
CONNIXTECH’s 2025 catalogue lists an M23 Square Self-locking 5PIN configuration for E-mobility / Industrial applications at 50A / 300V / IP67. This catalogue-listed configuration gives project teams a verified starting point for discussion. The final electrical use of each contact, counterpart components and assembled installation conditions must still be confirmed for the actual project.
Begin with the connection location and circuit requirements
First, identify where the connection is located in the equipment. It may be part of a battery-related assembly, an industrial machine connection point, a cable harness or another powered interface. Describe the equipment type, the available installation space and the expected access for assembly or service.
Then list the required current and voltage for each circuit. This information is more useful than a pin-count request on its own. It gives the project team a way to review the overall connection path and discuss whether the M23 5PIN catalogue configuration is relevant to the required application.
Avoid assuming that a similar M23 component is compatible with the planned cable or equipment interface. The cable-side and equipment-side parts, contact functions and final mating arrangement all need to be evaluated as a complete system.
Use the 5PIN configuration as a review point
The M23 Square Self-locking 5PIN entry is a defined catalogue configuration, not a universal wiring template. In a project inquiry, explain the required circuit functions without assigning a generic function to each contact. Provide a circuit list, pin-definition document or drawing when one is available.
This method helps avoid unnecessary revisions later in the process. It also keeps the discussion focused on the real equipment requirement rather than an unsupported assumption based on the connector shape or a product photograph.
For projects that also require broader power-path planning, see our guide to high-current connectors for battery energy storage systems. That article addresses the project information needed for high-current energy storage interfaces; it does not replace a configuration review for an M23 connection.
Plan the cable and mating arrangement together
Cable outer diameter, cable length and routing direction should be included in the RFQ. Explain how the cable will approach the equipment and whether there are space restrictions around the connection point. If the project involves a panel, enclosure or field-installed assembly, include a simple drawing or photo when possible.
The mating arrangement is equally important. Define the cable-side and equipment-side connection that the project requires, along with the expected mating direction and service access. A self-locking connector can only be reviewed properly when the complete installation arrangement is known.
Consider IP67 in the assembled condition
The M23 5PIN configuration is catalogue-listed as IP67. The protection requirement should still be discussed in the context of the complete mated assembly, cable interface and actual operating environment. Buyers should describe expected exposure, equipment position and the finished installation arrangement rather than treating an IP rating as a standalone project specification.
This approach is relevant for both e-mobility and industrial projects, where the connection may be influenced by cable routing, handling, enclosure design and service procedures. A complete project brief helps guide a practical review.
Prepare an M23 5PIN project inquiry
For a more useful review, submit the following information:
- Application type and equipment connection location.
- Required current and voltage for each circuit.
- Circuit-function list, drawing or pin-definition information.
- Cable outer diameter, length and routing direction.
- Cable-side and equipment-side mating arrangement.
- Assembled environmental conditions, required quantity and target timing.
