Non-voltage contact or NPN open-collector transistor

External synchronization input (Voltage between ES+ and ES– )
Low: 0 to 1 V
High: +V or open

Notes: 1)	When ES+ (pink) and ES– (pink/blue) of external synchronization input are connected, both HIGH and LOW comparative outputs are triggered in the mode selected by the external synchronization selection switch. If the external synchronization function is not used, always short-circuit ES+ and ES– and set the external synchronization selection switch to gate trigger.
2)	To use the analog output (gray), choose a device with an input impedance of 1 MΩ, or more, and connect the shield wire of the analog output to 0 V (common input) of the device.
3)	Insulate all unused wires individually to avoid miscontact.
