*1.Values in parentheses indicate the minimum required distance between the Sensor and Reflector.

*2.The model number of the Emitter is expressed by adding an "L" to the set model number in the table. Example: E3T-ST11-L 2M
The model number of the receiver is expressed by adding a "D" to the set model number in the table. Example: E3T-ST11-D 2M
Orders for individual Emitters and Receivers are accepted. (Modifications are required for some models.)

*3.Ask your OMRON representative about the previous Retro-reflective Sensors: E3T-SR2[] and E37-SR3[].

*4.Models are available either with or without the E39-R37-CA Reflector included.
Model with E39-R37-CA Reflector: E3T-SR4[]-S
Model without Reflector: E3T-SR4[]-C

Variety of Connection Specifications

The models with the connection specifications marked with a black circle in the table are available. The model number indication is a combination of the basic model and the connection specification.

*The sensing distance depends on the Reflector that is used. The sensing distance is 200 mm if an E39-R4 is used and 100 mm if an E39-R37-CA is used.
