By combining gear sensors with our F/V converters, tachometers, high-speed pulse counters, etc., real-time measurement of rotational speed, angle, and more becomes possible, offering various advantages.
High Precision & High-Speed Response
Achieves high precision and high-speed response under all conditions, from stop, ultra-low speed to high speed, rapid acceleration, and rapid deceleration using the PeriomaticTM method F/V converters and tachometers.
| > What is PeriomaticTM |
Improved Measurement Reliability and Safety
Peace of mind with equipment matching from a single manufacturer. Factory setting changes are also available (for measuring instruments).
*Image for illustrative purposes
Capable of Supplying Power to Sensors*
Eliminates the need to prepare a separate power supply for sensors.
*Optional for certain models. GP series does not require a power supply.

Output Circuit
Voltage output proportional to speed*3
0.5Vp-p or more
Self-generating type using a magnet and detection coil. No power supply required
Approaches gear tips, etc., and outputs a frequency signal proportional to the rotational speed
*1 Semi-open collector (open collector + pull-up): A proprietary output circuit developed by our company that allows connection as-is even if the pull-up voltage at the signal receiving end is higher than the sensor power supply voltage.
Unlike a simple open collector, pulse output with a voltage close to the sensor power supply voltage can be obtained.
*2 Differential (balanced) CMOS logic can be used as an unbalanced signal. When using as a balanced signal, please check the power supply voltage and output voltage specifications.
*3 The output voltage of the GP type is proportional to the speed in principle, but the GP type prevents unnecessary increases in output to improve reliability.
