Sensors: 2-Channel Differential-Hall M18 series
Sensors: 2-Channel Differential-Hall M18 series
Product Overview:
The RHEINTACHO M18 series speed sensor is a 2-channel differential-Hall sensor designed for measuring rotational speeds and directions of gearwheels. It is suitable for vehicles, mobile machines, and electric/hydraulic drives.
Key Features:
- Wide frequency range with excellent EMC properties.
- Operates across a large gap with required alignment.
- Options for two frequency signals or one frequency and one digital direction signal.
- Output options: NPN or PNP.
Technical Specifications:
- Power Supply: 8 VDC to 32 VDC.
- Frequency Range: 0.1 Hz to 20 kHz.
- Operating Temperature: -40°C to +125°C (-40°F to +257°F).
- Protection Degree: IP67.
- Housing Material: Steel X12CrNiS18 8.
Mounting and Installation:
- DIN type thread with special alignment required.
- Maximum tightening torque: 12 Nm.
- Air gap for module 2: 0.2 mm to 2.5 mm.
- Handle with care to prevent damage to the sensor face.
Electrical Specifications:
- Current Consumption: <33 mA at 24 V (both outputs low), <23 mA at 24 V (both outputs high).
- Short Circuit Immunity and Reverse Polarity Protection: Yes.
- Insulation Strength: 500 VDC.
Environmental Conditions:
- Shock Resistance: 30 g at 11 ms, 3x each direction.
- Vibration: 15 g from 3 Hz to 2000 Hz, 10 cycles per direction.
- MTTF: 130.5 years at +100°C.
Safety and Handling Instructions:
- Ensure safe conditions before commissioning.
- Replace defective components.
- Maintain distance from heat sources and radio systems.
- Inspect for transport damage.
Connection Details:
- 4-pin Binder plug, M12 (male type).
- Pin assignments include VDC, frequency signals, and ground.
Specifications and Intended Use:
The sensor must operate within specified ranges for voltage, temperature, vibration, shock, and environmental influences. Usage outside these conditions can lead to life-threatening situations or damage.
Improper Use:
Any use not described under 'Intended Use' is improper. The sensor is not suitable for explosive environments. Damages from improper use void warranty and liability claims.
Connection and Wiring Guidelines:
Sensor lines should be shielded, short, and connected with low resistance. Connect or disconnect the sensor only when de-energized. Cables should be kept away from large electric machines.
Use in Safety-Related Functions:
The customer must conduct a risk analysis and define safety-related functions. Suitable safety measures are the customer's responsibility.
Disposal:
The sensor must be disposed of according to national regulations.
Technical Changes and Liability:
Technical changes may occur without notice. Liability for errors is excluded. A printed CE-Conformity declaration is available on request.
