Product Description

Description
The speed sensors are suitable, in conjunction with a pole wheel, for generating square wave signals proportional to rotary speeds. They have a static behavior, i.e. the pulse generation is guaranteed down to a speed corresponding to a frequency of 0 Hz. The monitoring elements consist of magnetically biased differential hall-effect semiconductors. The internal two channel structure requires that the sensor must be oriented.

The attention of sensor mounting
These sensors use Hall probes. Therefore, the housing has to be aligned to the Installation pole wheel according to the sensor drawing. Deviations in positioning may affect the performance and decrease the noise immunity of the sensor.
The sensor should be mounted with the middle of the face side over the middle of the pole wheel. Dependent upon the wheel width, a certain degree of axial movement is permissible. However, the middle of the sensor must be at minimum in a distance of 3mm from the edge of the pole wheel under all operating conditions.
A solid and vibration free mounting of the sensor is important.
Eventual sensor vibration relative to the pole wheel can induce additional output pulses.
During installation, the smallest possible pole wheel to sensor gap should be set.
The gap should however be set to prevent the face of the sensor ever touching the pole wheel. Within the air gap specified the amplitude of the output signals is not influenced by the air gap.
The sensors are insensitive to oil, grease etc. and can be installed in arduous conditions.
The protective cap has to be removed before installation. The sensor has to be handled with care to prevent damage of the front face.
Connection  
The sensors must be connected according to electrical connecting diagram, Sensor wires are susceptible to radiated noise. Therefore, the following points have to be considered when connecting a sensor. The shield must be connected to the to 0 Volt of power supply or to specifically designated clamps
The sensor wires must be laid as far as possible from large electrical machines They must not run parallel in the vicinity of power cables. The maximum permissible cable length is dependent upon the sensor voltage, the cable routing, along with cable capacitance and inductance. However, it is advantageous to keep the distance between sensor and instrument as short as possible. The sensor cable may be lengthened via a terminal box located in an IP20 connection area in accordance with DIN40050.
