What are Lumberg Automation products used for?

Lumberg Automation products make machine wiring easier to install, troubleshoot, and maintain. Their connector systems help keep sensors, actuators, and industrial network devices securely connected in demanding automation environments where vibration, moisture, washdown, and daily equipment movement can cause wiring failures.

Choose the right Lumberg connector for the job

🟢

M12 Micro Connectors

Use M12 cordsets and receptacles for common sensor, actuator, and machine I/O wiring. They are a strong fit when equipment needs compact connections that still hold up in industrial conditions.

Typical fit: proximity sensors, photoeyes, valve manifolds, machine panels, robotics cells, and field I/O.
🟠

M12 Power Connectors

Choose M12 power connectors when the device needs more than signal wiring. Lumberg M12 power cordsets are used for compact AC or DC power delivery where space is limited.

Typical fit: AC motors, auxiliary power, frequency inverters, DC power supplies, Ethernet systems, and network devices.
🔵

M8 Pico Connectors

Use M8 molded cordsets when space is tight and the device does not need the larger footprint of an M12 connector. They help keep small sensors wired cleanly without oversized cable ends.

Typical fit: compact sensors, small actuators, tight machine frames, and dense automation assemblies.
📦

M12 Distribution Blocks

Use M12 distribution blocks to consolidate multiple field devices into one organized connection point. Passive blocks simplify wiring, while active blocks support networked automation layouts.

Typical fit: sensor banks, machine modules, Ethernet, Profinet, Profibus, and IO-Link installations.
🌐

Ethernet Connectors

Use Lumberg Ethernet connectors to connect industrial network devices where commercial RJ45 hardware is not rugged enough. Options include Ethernet cordsets, receptacles, field-wireable plugs, and RJ45-to-M12 adapters.

Typical fit: PLC network ports, Ethernet/IP devices, remote I/O, machine-mounted switches, panel-to-field network runs, and RJ45-to-M12 transitions.
🔌

7/8" Power Connectors

Use 7/8" power connectors when field devices need heavier power wiring than a compact sensor cordset can provide. Lumberg options include molded cordsets and field-wireable power connectors.

Typical fit: valve banks, power distribution blocks, field-mounted I/O, larger sensors, actuator groups, and equipment that needs heavier field power wiring.
⚡

M23 Connectors

Use M23 connectors when one connection needs to carry more conductors for power, signal, or combined machine wiring. They are a practical choice for larger automation devices that need secure circular connections.

Typical fit: servo motors, motor feedback, multi-conductor machine wiring, encoder connections, power/signal interfaces, and equipment that needs more pins in one circular connector.

Quick connector comparison

Product Type Use It For Practical Advantage Common Selection Check
M8 Cordsets Small sensors and compact actuator wiring Fits tight machine spaces Confirm pin count, cable length, and straight vs right-angle body
M12 Cordsets Machine I/O, sensors, actuators, field devices Reliable standard for automation wiring Check coding, gender, pin count, shielding, and IP rating
M12 Power Compact AC or DC power connections Adds power capacity without oversized connector hardware Confirm voltage, current, coding, and cable jacket
Ethernet Industrial Ethernet/IP, device networks, RJ45-to-M12 transitions Protects network connections on equipment Confirm D-coded M12, RJ45 interface, and required IP rating
7/8" Power Field power, valve banks, distribution systems, larger devices Handles heavier device power wiring Confirm 4-pin or 5-pin, AWG, straight or right angle, and length
M23 High density multi-pin power and signal connections Combines more conductors in one rugged interface Check 12-pin or 19-pin layout, cable length, and straight vs right-angle

✅ Quick reference checklist before ordering

Confirm connector size: M8, M12, 7/8", or M23.
Match gender, pin count, and straight or right-angle body (where applicable).
Check voltage and current before using a connector for power.
Use shielded cables for noise-sensitive signals or network lines.
Choose IP-rated products for washdown, dust, or outdoor exposure.
Verify cable length before routing through moving equipment.

Lumberg Automation FAQ

What is the difference between M8 and M12 connectors?

M8 vs M12 refers to the size of the mating thread. M8 connectors are smaller and work well for tight sensor spaces. M12 connectors are larger and more common for standard machine I/O, sensor, actuator, and field device wiring.

When should I use Lumberg Ethernet connectors?

Use Ethernet connectors when connecting industrial network devices such as PLCs, I/O blocks, Ethernet/IP equipment, and M12-to-RJ45 network transitions on machinery.

When should I use 7/8" power connectors?

Use 7/8" power connectors for field power connections where devices need heavier wiring than small sensor cordsets. They are often used with power distribution, valve systems, and larger field-mounted equipment.

What are M23 connectors used for?

M23 also refers to the size of the mating thread. These larger connectors are used for high density multi-pin power and signal connections on automation equipment. They are useful when one connector needs to carry more conductors than smaller M8 or M12 styles.
