E3Z-LT/LR/LL
CSM_E3Z-LT_LR_LL_DS_E_6_4

Compact and Reliable
Laser Photoelectric Sensor
• Safety and reliability with laser class 1 (JIS and IEC).
• Product lineup includes models with distance setting without influence of
color.
• Maximum ambient operating temperature of 55°C and water-proof
construction in E3Z class.

*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 ofthe 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 orM8 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.)
