Sensing characteristics

Cautions For Use

I/O Circuit and Wiring diagrams

I/O circuit diagrams

When selecting NPN output

Non-voltage contact

When selecting PNP output

Non-voltage contact or PNP open-collector transistor output

High [+5 V to +30 V DC (source current 0.04 mA or less)] : Effective
Low (0 to 0.6 V DC or open) : Ineffective

Analog output (common in NPN output type and PNP output type)

Notes:

1)	Analog output is not equipped with the short-circuit protection. Do not short-circuit or apply voltage to them.
2)	Use shielded wires for analog outputs.

Communication specifications (High function type)

The **HL-G1** can be connected to upper devices of RS-422/485.
When upper device sends the request command, the **HL-G1** series send the response command.
Communication method	RS-422	RS-485
	Full duplex	Half duplex
Synchronization method	Asynchronous communication method
Transmission code	ASC ll
Baud rate	9,600/19,200/38,400/115,200/230,400/460,800/921,600 bps
Data length	8 bits
Stop bit length	1 bit
Parity check	None
BCC	Yes
Termination code	CR

RS-422 1-to-1 connection

Notes:

1)	The transmission data cable and reception data cable are both twisted-pair cables.
2)	The shield is connected to the 0 V side of the power supply line inside the sensor.
3)	Be sure to connect the signal ground.
4)	The sensor is of non-isolated type. Make sure that the potential difference between the sensor and RS-422 connecting device does not exceed 4V. A difference in potential in excess may cause the connecting device or the sensor to malfunction.

RS-485 1-to-N connection

Connectable up to 16 units.
Please set the prefix with no duplication.

Notes:

1)	The transmission data cable and reception data cable are both twisted-pair cables.
2)	The shield is connected to the 0-V side of the power supply line inside the sensor.
3)	Be sure to connect the signal ground.
4)	The sensor is of non-isolated type. Make sure that the potential difference between the sensor and RS-485 connecting device does not exceed 4V. A difference in potential in excess may cause the connecting device or the sensor to malfunction.
5)	The sensor has a built-in terminating resistor. Be sure to turn ON the terminating resistor of the terminating sensor.
6)	Perform transition wiring for the transmission path.
7)	Connect the wires according to the specification of the equipment.
