Applications of M12 5-Pin A-Coded Connectors

✅ 1. Sensor/Actuator Connections

Used to connect proximity sensors, inductive sensors, photoelectric sensors.
Common in packaging, assembly, and robotics automation lines.

✅ 2. IO-Link Devices

Ideal for connecting IO-Link masters and devices for smart sensing and diagnostics.

✅ 3. Encoder Feedback

Transmits encoder signal data (e.g., A/B/Z pulses) for motion control systems.

✅ 4. Low-Voltage DC Power + Signal

Supplies 24V DC power and supports additional I/O or control lines in one compact cable.

✅ 5. PLC and Field I/O Modules

Used in distributed control systems to link field devices to PLC I/O cards.

Typical 5-Pin A-Coded Pinout

Pin	Signal	Description
1	+V	Power Supply (+24V DC typically)
2	DI/DO	Digital Input/Output
3	0V	Ground
4	DI/DO	Digital Input/Output
5	DI/DO or Shield	Optional I/O or Shield

⚠️ Always check the device datasheet – pin functions can vary by manufacturer.
