*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.
The following connection forms are also available. 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, M8 3-pin connectors, or e-CON connectors.
*4.Consult with your OMRON representative if a distance of more than 10 m is required. Models with large custom-size spots can be produced. These make optical axis adjustment easier and allow the beam to be received more stably by the Receiver even if vibration is present.
Accessories
Slits (for E3Z-LT[][])
| Slit width | Sensing distance | Minimum detectable object (typical) | 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 (for E3Z-LR[][])
| Name | Sensing distance (typical) | Model | Remarks |
| 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 | ||
