IMG12/16 Magnetic Gear Speed Sensor

> To Product Page
Noise Suppression & Power Reverse Connection Protection

Response 0 - 20kHz
Temperature -20 to +105°C
Power Supply DC4.5 - 25(17)V

Output Circuit
Semi-Open Collector*1
Line Driver
Differential (Balanced) CMOS Logic*2

Detects from 0Hz, enabling accurate rotation measurement via jitter suppression technology

Line driver output type supports environments with long wiring

Equipped with a power reverse connection protection circuit to prevent failures due to wiring mistakes

FDP10/16 Magnetic Gear Speed Sensor

> To Product Page
Full Thread, General-Purpose, Easy Installation

Response 0 - 15kHz
Temperature -20 to +80°C
Power Supply DC4.5 - 25V

Output Circuit
Semi-Open Collector*1

Pursuing ease of use as a general-purpose sensor

Output circuit is unbalanced, obtaining an output voltage almost equivalent to the sensor power supply voltage

Equipped with a semi-open collector output circuit so it can be connected directly even if the pull-up voltage of the signal receiving end is higher than the sensor output

FP12T-50 Magnetic Gear Speed Sensor

> To Product Page
Wide Temperature Range

Response 10 - 30kHz
Temperature -40 to +150°C
Power Supply DC5 - 12V

Output Circuit
Open Collector


Built-in amplifier, usable in high temperatures (150°C)

RFP16A/D Magnetic Gear Speed Sensor

> To Product Page
Detects Both Forward & Reverse Directions with 1 Sensor

Response 0 - 15kHz
Temperature
-40 to +140°C (RFP16A Power Supply under 15V)
-40 to +126°C (RFP16A Power Supply 15V or higher)
-20 to +80°C (RFP16D)
Power Supply DC9 - 25V

Output Circuit
Semi-Open Collector*1
(A/B Phase or Speed/Direction Discrimination Signal)

Detects both forward and reverse directions with 1 sensor. Reduces work hours such as hole drilling and mounting adjustments

*Supports m1/1.5/2 / Involute gear verified

GP12/16 Self-Generating Electromagnetic Pickup

> To Product Page
Self-Generating Type Requiring No Power Supply

Response 220 - 50kHz
Temperature -20 to +100°C
Power Supply No Power Required

Output Circuit
Voltage Output Proportional to Speed*3
0.5Vp-p or higher

Self-generating type with magnet and detection coil. No power supply needed

Approaches gear tips, outputting a frequency signal proportional to rotation speed

*1 Semi-Open Collector (Open Collector + Pull-up): Our proprietary output circuit allowing direct connection even when the pull-up voltage of the signal receiving end is higher than the sensor power supply voltage.
Unlike a simple open collector, it yields pulse output with a voltage close to the sensor power supply voltage.
*2 Differential (Balanced) CMOS Logic can be used as an unbalanced signal. When using as a balanced signal, please verify the power supply and output voltage specifications.
*3 Although the output voltage of the GP type is proportional to speed in principle, the GP type prevents unnecessary increases in output to improve reliability.
