Comparing Pinout Configurations Between Male and Female Connectors

Understanding the pinout configurations for both male and female M16 5-pin connectors is crucial for proper wiring and functionality. The pinout details provide information about how the pins are arranged and connected.


Pinout Configuration for Male Connector

The male M16 5-pin connector typically has the following pinout configuration:


Pin NumberPin NameDescription
1Power (P)Provides power supply to connected devices
2Signal 1 (S1)Carries low-level signals or data
3Signal 2 (S2)Carries another low-level signal or data
4Ground (G)Provides a common reference for signal and power
5Signal 3 (S3)Carries another low-level signal or data

Pinout Configuration for Female Connector

The female M16 5-pin connector has a corresponding pinout that matches the male connector:


Pin NumberPin NameDescription
1Power (P)Receives power supply from connected devices

【Circular waterproof plug-in push-pull self-locking connector】Principle of push-pull self-locking connector
Push pull self-locking connector is a reliable connector, which works by locking the plug and socket together through an internal locking mechanism. Circular push-pull self-locking connectors usually consist of a plug and a socket. The socket is usually installed on the device, while the plug is installed on the connecting wire. When connecting, insert the plug into the socket and push the plug forward until the internal locking mechanism between the plug and socket locks them together. This connection method does not require any external attachments such as threads or buckles, making it very convenient and fast, and also safer and more reliable.
