1. Balluff
- Where to use: sensors (proximity switches, pressure sensors, displacement sensors)
- Typical products:
Balluff BAW series, BES series sensors
- Features:
Usually 6 cores will transmit sensor power (+24V, GND) and multiple signal lines (such as normally open/normally closed, alarm, and status feedback).
2. SICK
- Where to use: laser distance sensors, smart sensors
- Typical products:
SICK DT35, WT12-2, WLG4S series
- Features:
6-core cables are generally used for sending and receiving, measuring feedback, and communication (such as IO-Link signals).
3. IFM
- Where to use: industrial automation monitoring, flow sensors, temperature transmitters
- Typical products:
IFM TN series (temperature sensors), SM series (flow sensors)
- Features:
Common M8 6P connection, power supply + switch quantity + analog output share 6 cores, and the open end is convenient for connecting to PLC.
4. Truck
- Where to use: Sensors and valve island modules
- Typical products:
Turck Bi-Sensors, distributed I/O modules (such as the BL67 series)
- Features:
Some Turck devices support IO-Link or multi-channel IO, which requires more than 6 pins to connect, and M8 6P lines are very common.
5. Festo
- Where to use: pneumatic valve islands, small actuators
- Typical products:
Festo CPV, VTUG series solenoid valve islands
- Features:
Multi-position valve islands are connected through M8 6P lines, and the open end directly pulls the signal into the PLC cabinet, reducing the number of intermediate modules.
