M40 circular connector
M40 circular connectors for demanding applications
A circular connector is used to connect two devices to each other. The electroconductive contacts enable the communication of power, signals or data by establishing a circuit through the connection. As a power connector, the M40 circular connector covers a wide range of applications and offers individual solutions in power and signal transmission.
It can be used as a cable connector, coupling connectors and a panel connector. The extensive M40 connector range helps you to select the right product for different applications. The technical and environmental conditions must be taken into account here.
The required current, voltage and weather conditions are parameters for which there are suitable M40 connectors. The M40 connectors are compatible with all common standard products.
Different types of M40 circular connectors
The design and type of the M40 connector types from the brand manufacturer Hummel have differences that offer great flexibility in a wide range of applications. All types are classified with the protection class IP67 and are optimally sealed so that they have dust protection and can withstand moisture intermittently. The overview of the M40 power connectors illustrates the differences.
- M40 cable connectors: These connectors are designed for socket inserts and are equipped with a knurled nut or Twilock-S. This new sealing technology from Hummel sets itself apart thanks to its easy handling with optimum functionality. With just one click and one twisting motion, the plug-in systems are locked. This quick-action locking technology is compatible with the tried-and-tested screw locking system.
- M40 coupler connector: With a pin insert, the shielded version with connector is the first choice for transmitting sensitive data and signals. The contact is located at the end of the wire. The connector has a rated voltage of 600 V at 55 A and with >500 mating cycles has a long service life. The robust housing makes use in harsh environments possible. It can withstand temperatures from -40° C to 125° C.
- M40 panel connector: The unshielded M40 connector consists of a pin and socket in an angled shape. Equipped with a crimp connection, it is suitable for front wall mounting. The classic connector is used as the locking method.
The M40 connectors ensure a secure connection in many sectors and different industrial applications, whether power supply or signal control, such as in automation, machine and plant construction and feedback applications.
Flexible pinout/coding with M40 connectors
With the M40 connector pinout, the signal, data and power transmissions to be transmitted can be coordinated. The respective task is assigned to individual cables and these cables are connected together to the connector. The individual M40 connectors coding prevents mismating.
Available numbers of pins for M40 connectors from Hummel
A wide range of signal, data and information streams can be defined via pins in the connector. The more pins there are, the more communication can be effected via the connector. The compact power cable takes up little space. The connector is available with the following standard numbers of pins:
- M40 connector 6-pin
- M40 connector 8-pin
