M12 connector 5PIN

1. Straight and curved:

Straight type: the connection head is straight, suitable for installation on the plane.
Bend type: the connection head has a 90° bend Angle, which is suitable for installation in narrow space or the occasion where corner wiring is required.


2. Wiring type and plate end type:

Wiring type: The connection head with cable lead wire is used to connect the equipment to the control system.
Board end type: the connection head is installed directly on the circuit board for board connection inside the device.


3. Front and back locks

Front lock: the front part of the connecting head is provided with a rotating nut, and the connection and disconnection are realized by turning the nut. Convenient and quick connection and disassembly, simple operation. Suitable for frequent disassembly and assembly application scenarios
Rear lock: the rear part of the connection head is provided with a fixing screw, and the connection is fixed through the fixing screw. The connection is more solid and reliable, and the vibration resistance is good. Suitable for fixed installation or vibration environment applications


4. Male and Female heads:

Male head: A connection head with raised pins for connecting cables.
Female head: A connection head with a socket installed on the device for connecting the male cable head.


5. Direct and serial:

Straight: Single connection head for point-to-point connection.
Serial: Multiple connectors are integrated for cascading connections to multiple devices.


6. With and without shielding:

With shielding: with metal shielding inside, can effectively suppress electromagnetic interference.
No shield: the structure is more simple and compact, suitable for the occasion of less electromagnetic interference.


The M12 Industrial connector offers a variety of configuration types to meet the different installation, wiring and interface requirements of the industrial automation field. Engineers can choose the most suitable M12 connector to build reliable and high-performance industrial systems according to the specific application environment and requirements.
