Ordering Information

Red light

Infrared light

M2-mounting Sensors

A set of mounting screws is included with the Sensor.

M3-mounting Sensors

A set of mounting screws is not included with the Sensor. Order a Screw Set separately if required.

Small Cylindrical Sensors

A set of mounting nuts is included with the Sensor.

*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. Models are available either with or without the E39-R37-CA Reflector included.
