Magnetic Gear Tooth Speed and Direction Sensor 　RFP Series

Direction determination with one

Constructed from hall elements, a magnet, and a signal processing circuit.
It converts the difference of magnetism into the electric signal, and outputs the logic pulses.

[Product Introduction Video] Japanese only
Detects both
forward and reverse		 Reduce drilling during installation, installation time and costs, etc.
conventional product
2 sensors are required for
both forward and reverse detection.		 RFP16
1 sensor detects both
forward and reverse.
Supports m1, 1.5, 2
Design flexibility is high and management cost can be reduced.
Detection from 0Hz
Confirmation of fine movements at the moment of starting and stopping.
-40℃ to ＋140℃
Operating tempereture for RFP16A with supply voltage 7-15V DC.
[15-25V DC]-40°C to +126°C　　[RFP16D]-20°C to +80°C.
IP67: Leak-free head Metal case with integrated tip and body / Conical PressTM cable withdrawal technology.

Includes Setting card Check the different mounting angles for each gear module with a single card.
Align the direction of the arrow on the card
with the forward direction of the gear and
check the mounting angle.
G: Forward direction of gear
