*1 PNP open-collector output rating: 50 mA max. (30 V max.), Residual voltage: 0.5 V max.
Voltage input rating: Maximum input rating: 26.4 V, ON voltage: 10.2 V, OFF current: 0.6 mA
*2 Part of the input/output circuit of the LK-G5000 Series is internally common. Be careful that no potential difference is generated between the internally common terminals due to the potential difference between the cables/external devices. For details, refer to "Precautions on wiring" in the User's Manual.
*3 This input is applied to all of the synchronized OUT.
*4 When the laser class 3B sensor head is connected, a key-operated switch must be used for the input to this terminal. The laser is emitted only when the key-operated switch is set to the ON position. (Select a key which can be removed only when it is set to the OFF position.)
When the laser class 2/3R sensor head is connected, the laser turns on when this terminal is opened and turns off when it is short-circuited.
*5 When a PC supporting USB 1.1 or USB 2.0 full speed is connected, the data refresh cycle and other operations may slow down.
*6 Use the Ethernet interface only for direct connections with a PC or for local network connections with a PC or LK-G5000 Series units.
*7 The EtherNet/IPTM interface cannot be used when a CC-Link unit or a DeviceNetTM unit is installed.
EtherNet/IPTM is supported by the latest controllers. For details on which controllers support EtherNet/IPTM , contact your nearest KEYENCE office.
