Accessories

Slits

(A Slit is not provided with a Through-beam Sensor. Order a Slit separately if required.)

Slit width	Sensing distance	Minimum detectable object (reference value)	Model	Contents
0.5 mm dia.	3 m	0.1 mm dia.	E39-S65A	One set (contains Slits for both the Emitter and Receiver)

Reflectors

(A Reflector is required for each Retro-reflective Sensor: A Reflector is not provided with the Sensor. Be sure to order a Reflector.)

Name	Sensing distance		Model	Remarks
	Rated value	Reference value
Reflector	---	15 m (300 mm)	E39-R1	Retro-reflective models are not provided with Reflectors. Separate the Sensor and the Reflector by at least the distance given in parentheses. The MSR function is enabled.
	7 m (200 mm)	---	E39-R12
	---	7 m (200 mm)	E39-R6

Note: If you use the Reflector at any distance other than the rated distance, make sure that the stability indicator lights
         properly when you install the Sensor.

Mounting Brackets

A Mounting Bracket is not provided with the Sensor. Order a Mounting Bracket separately if required.

Appearance	Model	Quantity	Remarks
	E39-L153 *1	1	Mounting Brackets
	E39-L104 *1	1
	E39-L43 *2	1	Horizontal Mounting Bracket

	E39-L151	1 set
	E39-L144 *2	1	Compact Protective Cover Bracket (For E3Z only)

Note: When using a Through-beam Sensor, order one Mounting Bracket for the Receiver and one for the Emitter
*1. Cannot be used for Standard Connector models with mounting surface on the bottom. In that case, use Pre-wired
       Connector models.
*2. Cannot be used for Standard Connector models.

Sensor I/O Connectors (Sockets on One Cable End)

(Models for Connectors and Pre-wired Connectors: A Connector is not provided with the Sensor. Be sure to order a Connector separately.)

		L-shaped *1 *2		2 m		XS3F-M422-402-A
				5 m		XS3F-M422-405-A

Note: When using a Through-beam Sensor, order one Mounting Bracket for the Receiver and one for the Emitter
*1. The connector will not rotate after connecting.
*2. The cable is fixed at an angle of 180° from the sensor emitter/receiver surface.

* Models numbers for Through-beam Sensors (E3Z-LT[][]) are for sets that include both the Emitter and Receiver.
    The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3Z-LT61-L 2M),
    the model number of the Receiver, by adding "-D" (example: E3Z-LT61-D 2M.) Refer to Ordering Information to
    confirm model numbers for Emitter and Receivers.
