Amplifiers D3RF series
D3RF series
Amplifiers D3RF series
16µsec response, long sensing distance,
finest in digital-class amplifiers.
High speed digital fiber sensor
Widest display in the class
5mm wider display than conventional D2RF.
7 segment with high brightness LED for better
visibility.
Easier operation
More than 2 sec. pressing the button for teaching.
Higher functionality is in deeper setup layer. These
prevent miss-operations.
Dual “ASC” for easy maintenance
Detects light degradation made by some dust and
adjusts the brightness. It re-adjusts threshold auto-
matically after cleaning up so no need re-teaching.
100% display for better
recognition of change
Display can be changed to percentage (0~100) by
simple single action with buttons. Easy to recognize
when the level changes.
Brightness stabilizing function
“FALUX”
Our original technology “FALUX” stabilizes LED
brightness by adjusting LED current even under
fluctuation of LED temperature after power up.
Adjustable hysteresis
Hysteresis can be adjusted from 1% to 40% as you
like. This enables flexible setup of sensitivity accord-
ing to various object condition.
Fastest in the class
16µs(1-HS mode)
22µs(inter-connection type)
Originally developed super high speed processor
“FAntron DUO” enables fastest speed in the class 16
µs (1-HS mode). It can detect over 30,000 pieces per
second. Maximum speed of inter-connection type is
22us. It can prevent cross talk up to 2 units.
Super sensing distance
Utilizing our original pulse emitting method, High
power LED and efficient collective lens, it can receive
enough light to realize around 3 times longer sensing
distance for diffuse and 5 times longer sensing
distance for thru-beam sensing.
ECO mode
It has ECO mode that enable power saving by
making sub-display (green) OFF and darken main-
display (red).

Without FALUX With FALUX
Sensing level changes when light path
got some contamination and then it
works wrongly . It needs re-teaching.
Threshold level is adjusted optimized
level automatically according to
sensing level continuously.
