E3T
Small Cylindrical Sensors A set of mounting nuts is included with the Sensor.
Accessories (Order Separately)
Accessories for M2-mounting Sensors These accessories are not included with the Sensor. Order them separately if required.
*1.When using Through-beam Sensors (E3T-ST@@, E3T-FT@@), order one Bracket for the Emitter and one for the Receiver.
*2.Order two Sets, one for the Emitter and one for the Receiver, for Through-beam Sensors (E3T-ST@@ or E3T-FT@@).
This is the Screw Set for mounting the Sensor to the Mounting Bracket. Order this Set if you lose the screws. Do not use this Screw Set to mount the Mounting
Bracket to the equipment.
*3.This is included with the Sensor.
