Use these connectors with servomotor, servocontrollers, and servodrives in automated equipment and assembly lines. Rated NEMA 4X, IP67, and IP69K, they resist corrosion and protect against high-pressure, high-temperature washdowns. When mating connectors, the gender, housing thread location, and pole layout must be opposite. Poles are numbered on the face of the connector.

Power connectors deliver electricity to run a servomotor.

Signal connectors communicate between servocontrollers, servodrives, and servomotors.

Siemens-Compatible Servomotor M23 Connectors

4 Pole (Gray Poles Not Wired)

6 Pole

Choose a socket for your Siemens M23 plugs to power servocontrollers and servomotors in automated equipment and on assembly lines. Sockets mate with male plugs that have external housing thread and a clockwise pole layout. Poles are labeled on the face of the socket.

4-pole socket has six holes on the face; two holes are not wired.

Sockets with continuous-flex cables withstand frequent movement, such as in robotics.

Sockets with brake wires stop and hold a motor in a desired position.

M29 Power Receptacles

Male

Female

4 Pole Male

4 Pole Female

Mount these receptacles to control cabinets and equipment in order to quickly connect and disconnect M29 power cords. Because they carry higher currents than micro and mini receptacles, they often power motors, fans, pumps, and machine tools in automated systems. They meet UL 2237 and UL 2238, so they can be used in motor branch circuits of industrial machinery. IP rated, they protect against dust, washdowns, and temporary submersion.

M29 Power Cords

Plug × Socket

4 Pole

Often used in automation systems such as conveyors and sorters, these cords have plug and socket ends, so they quickly connect and disconnect for maintenance and do not need to be hardwired. Because these cords carry higher currents than micro and mini cords, they can power equipment such as motors, fans, pumps, and automated machine tools. They are shielded to block out interference from nearby equipment. These cords meet UL 2237 and UL 2238, so they can be used in motor branch circuits of industrial machinery. They also meet TC-ER crush and impact requirements for exposed runs in cable carriers. IP rated, they protect against dust, washdowns, and temporary submersion.

Connect these cords to control cabinets and equipment with M29 power receptacles (sold separately).
