Accessories for M3-mounting Sensors These accessories are not included with the Sensor. Order them separately if required.
*1.When using Through-beam Sensors (E3T-ST@@M@), order one Bracket for the Emitter and one for the Receiver.
*2. 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. Order two Sets, one for the Emitter and one for the Receiver, for Through-beam Sensors (E3T-ST@@M@).
Accessories for Small Cylindrical Sensors
*1.This Nut Set is for the Emitter/Receiver. This is the Nut Set for mounting the Sensor. Order this Set if you lose the screws.
Accessories for All Sensors
*1.Values in parentheses indicate the minimum required distance between the Sensor and Reflector.
*2. The E3T-SR4@ cannot be used with the E39-R37 or E39-RS1/2/3 (without CA) Tape Reflectors.
The E39-@-CA Reflector is for use only with the E3T-SR4@. It cannot be used with other Sensors.
