The RH Series
AI-Tek Instruments are the experts in magnetic hall effect sensors and have taken their years of experience in designing and manufacturing Hall Effect sensors for harsh applications. The RH Series is a line of durable hall effect sensors perfect for industrial, rail, military and automotive use.
The RH series sensors are single-element based, zero speed, single-channel speed sensors. These sensors are an excellent option if you are looking for general purpose speed sensing. Unlike the DH series that requires rotational alignment at installation, the RH requires no alignment. Air gap adjustment is precise and easy and similar to a VR type sensor.
Key Features of the RH Series
Suitable for 24 diametral pitch or coarser gear (target), the standard catalog sensors are easily applied to your various sensing needs. If you have a unique, special requirement that cannot be met with any of the standard options, we will gladly review your specs and work with you on a special sensor design.
How the RH Series Works
The RH sensor is hall-effect based and can sense each change in target movement, regardless of speed, from near zero to 15 kHz frequency range, generating a steady pulse train of frequency proportional to the target speed. Each time a gear tooth (or any ferrous discontinuity) passes in front of the sensor the output changes state. Installation is simple and requires no rotational alignment.
For applications with cable runs that exceed 500 feet, you will need to use a Digital Signal Distance Amplifier (DSDA).
