E4B
J SENSING TYPE
Through-beam
Detects the attenuation or interrupted condition of the ultrasonic beam caused by the object E4B-TjS Emitter passing between the Emitter and Receiver. Sensing object
E4B
E4B-TjR Receiver
Reflective
Setting distance
Detects only the beam reflected from the object existing within the sensing distance range set with the distance adjuster.
Distance adjustment E4B-LSj
Unstable range
Sensing object Sensing distance adjustable range
Setting zone
Sensing background
Detects the object with the interruption of the normal beam reflected from the acoustically reflective surface. E4B-RS70
Sensing object
Acoustically reflective surface
Sensing target
Detects only the beam reflected from the object existing in the sensing range set with the distance selector.
E4B-RS70
Unstable range
Sensing object
Note: An object may be detected due to multiple reflection if the object is in the unstable range where the distance adjuster is ineffective, in which case however, the detection of the object will not be stable. Therefore, do not attempt to use the E4B to detect an object in the unstable range.
