Ordering Information

Sensors (Refer to Dimensions on page 11.)

*1. The Reflector is sold separately. Select the Reflector model most suited to the application. *2. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. *3. Pre-wired Models with a 0.5-m cable are also available for these products. When ordering, specify the cable length by adding “0.5M” to the end of the model number

(e.g., E3Z-LT61 0.5M). M12 Pre-wired Connector Models are also available. When ordering, add “-M1J” to the end of the model number (e.g., E3Z-LT61-M1J). The cable is 0.3 m long. Also, the following connection forms can be manufactured. Ask your OMRON representative for details.

• Pre-wired Models with 1-m or 5-m cables

• Pre-wired Connector Models with M8 4-pin connectors or M8 3-pin connectors.

*4. Through-beam Sensors are normally sold in sets that include both the Emitter and Receiver.

Orders for individual Emitters and Receivers are accepted. (Modifications are required for some models. Ask your OMRON representative for details.)

Accessories

Slits (A Slit is not provided with a Through-beam Sensor. Order a Slit separately if required.) (Refer to Dimensions on page 14.)

Reflectors

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

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

(Refer to Dimensions on E39-L/F39-L/E39-S/E39-R.)

Note: When using a Through-beam Sensor, order one Mounting Bracket for the Receiver and one for the Emitter * Cannot be used for Standard Connector models.

Sensor I/O Connectors

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

(Refer to Dimensions on XS3, XS2)

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 su

rface.
