M12 5-Pin Male Right-Angle Connector – for industrial sensors and automation systems

M12 5-pin male right-angle connector for field wiring onto a cable – plug (male connector), A-coded, with screw terminals. The wires are screwed into the terminals, no soldering needed, and the connector takes cables with a diameter of 4–6 mm. The cable exits the connector at 90°.

Application

The M12 5-pin plug mates with an A-coded M12 5-pin socket – for example a device socket or a cable ending in a socket. The pin assignment is the same as in M12 sensors.

The connector is made to IEC 61076-2-101 (A-coded), so it also fits other brands' A-coded M12 sockets.

3	supply 0 V (L−)	blue (BU)

View of the contact side. The pin assignment and wire colours comply with IEC 60947-5-2, the standard used for connecting proximity sensors of different brands – Nexotec sensors and cables follow it too. In other devices, the pin functions are defined in their documentation.

Pin 5: Nexotec sensors have no fifth pin. 5-pin connectors are used, among other things, with shielded cables and cables with an earth conductor – in 5-core cables, pin 5 usually has a green-yellow wire (GN/YE). The function of pin 5 is defined by the device to which the cable is connected.

Installation and operating conditions

Cable: diameter 4–6 mm, conductors up to 1.5 mm². Connection: screw terminals. The wires are clamped with slotted screws (flat-blade screwdriver). Coupling nut tightening torque: 0.6 Nm. The connector achieves IP67 when plugged in and with the coupling nut tightened. Operating temperature: −40…+85 °C.

Frequently asked questions

Does the connector need soldering?
No. The wires are screwed into the screw terminals.

Are any tools needed for installation?
Yes – a flat-blade screwdriver. The wires are clamped in the terminals with slotted screws.

Which cable fits the M12 connector?
A cable with a diameter of 4–6 mm and conductors up to 1.5 mm².

How do I connect a sensor to the M12 5-pin connector?
According to IEC 60947-5-2: pin 1 – supply + (L+), pin 2 – second output (NC), pin 3 – supply 0 V (L−), pin 4 – output (NO). Pin 5 remains unconnected.

Is it suitable for an NPN sensor?
Yes. The pin assignment is the same for PNP and NPN sensors.

Is the connector sealed?
Yes – IP67, once the connector is plugged in and the coupling nut is tightened.

Is the connector shielded?
No, it is an unshielded connector.

Why is the 5-pin connector rated at 60 V and the 4-pin version at 250 V?
IEC 61076-2-101 specifies this voltage for A-coded M12 connectors with five contacts; the 3- and 4-pin versions are rated at 250 V AC/DC.

How many times can the connector be mated?
The connector withstands at least 100 mating cycles.

What other versions are available?
M12 5-pin connectors are also available as: female straight (F12-5S); male straight (F12-5MS); female right-angle (F12-5R).
