M5 Miniature Connectors for Service Robot Sensor Interfaces

M8 Waterproof Connector Types and Specifications

Selecting a Miniature Connector for Service Robot Sensor Interfaces

For sensor interfaces in service robots such as restaurant robots, the primary decision factor is miniaturization without compromising signal integrity. The M5 miniature series connector is a suitable choice for these applications.

Key Specifications of the M5 Miniature Series

• Diameter: 5 mm
• Weight: Less than 3 g
• Pin Count: 2–4 pins
• Plugging Force: Less than 5 N
• Protection Rating: IP65
• Temperature Range: -20 °C to 60 °C

Application Fit for Restaurant Robots

The M5 connector supports signal transmission for infrared and ultrasonic sensors. Its compact size and low plugging force make it well-suited for the narrow body spaces of service robots, including head and arm components. The IP65 rating provides resistance to food residues and water stains, while the temperature range is compatible with typical indoor operating environments.

Selection Considerations

When evaluating this connector for your design, confirm the following:

• Verify that the required number of signal lines does not exceed the available pin count.
• Check that the plugging force aligns with the mechanical constraints of the robot's assembly process.
• Ensure the operating temperature range of the robot's environment falls within the connector's rated limits.
