Sensor: 2-Channel Differential-Hall M18 Push-Pull
Sensor: 2-Channel Differential-Hall M18 Push-Pull
The document is a technical data sheet for the RHEINTACHO Messtechnik GmbH's 2-Channel Differential-Hall M18 series speed sensor, detailing specifications, applications, features, and safety instructions.
- Power Supply: 7 VDC to 32 VDC
- Frequency Range: 0 Hz to 20 kHz
- Operating Temperature: -40°C to +125°C (-40°F to +257°F)
- Degree of Protection: IP67 when the plug is connected
- Housing Material: Stainless steel 1.4305
- Output: Push-Pull
- Current Consumption: 30 mA at 32 V
- Short Circuit Immunity: Yes
- Reverse Polarity Protection: Yes
- Insulation Strength: 500 VDC
The sensor is used for detecting rotational speed and direction in gearwheels with small modules and high resolution, applicable in vehicles, mobile machines, and electric and hydraulic drives.
- Wide frequency range
- Requires alignment
- Precise phase shift and minimal jitter
- Handle the sensor carefully to prevent damage.
- Avoid installation near heat-generating parts.
- Unplug the sensor during electrical welding and painting operations.
- Shield and keep cables short.
- Only trained specialists should handle system developments and installations.
- Ensure the vehicle and hydraulic system are safe before commissioning.
- Do not use defective components.
- Contact RHEINTACHO for specific application instructions.
- Resistant to various hydraulic oils.
- Withstands a maximum pressure of 10 bar on the sensing surface.
- Vibration and shock resistance specified according to EN standards.
- Useful life period (MTTF) of 150 years at +60°C.
The sensor complies with standards including EN 12985:2015, EN13309:2010, ISO14982:2009, and EN 60947-5-2.
- Use within specified operational limits.
- Not suitable for explosive environments.
- Improper use voids warranty and liability claims.
- Ensure sensor cable extensions meet requirements.
- Avoid routing speed sensor lines near power-conducting lines.
- Secure cable harness near the sensor with spacing less than 150 mm.
- Preferably route wires inside the vehicle; if outside, ensure they are securely fixed.
- Avoid kinking, twisting, or routing wires through sharp edges without protection.
Operate the speed sensor within specified voltage, temperature, vibration, and shock ranges. Usage outside specified conditions may pose safety risks and cause damage.
Any use outside the intended scope is improper and not permissible in explosive areas. Improper use voids warranty and liability claims.
Customers must conduct risk analysis and define safety functions, implementing measures like sensor redundancy and emergency switches. Necessary product data for safety assessment is available upon request.
Dispose of the speed sensor according to national regulations.
Technical changes may occur without notice. Liability for errors is excluded. Printed declarations of conformity are available on request.
