All sensors have been fully tested prior to delivery. Proper function and safety of this position sensor is guaranteed as long as it is mounted, connected, and used within the appropriate specified values, and in accordance with the instruction manual. Warranty will be granted for a period of 12 months after delivery. Warranty is limited to repair or replacement at no charge. Defective parts will be repaired or replaced at no cost in cases of malfunction or damage caused by faulty materials or manufacture.. Safety instructions Do not use POSIROT® position sensors in safety critical applications where malfunction or total failure of the sensor may cause danger for man or machine. For safety related applications additional mechanisms (devices) are necessary to maintain safety and to avoid damage. Disregard of this advice releases the manufacturer from product liability. The sensor must be operated only within values specified in the catalog or datasheet. Connection to power supply must be performed in accordance with safety instructions for electrical facilities and performed only by trained staff. MAN-PR-E-09 www.asm-sensor.com ASM GmbH POSIROT® Instruction Manual Description The angle sensors PRAS/PTAS of the POSIROT® product family perform touchless or shaft based angle measurement. A position magnet rotates in front of the sensing area of the sensor head. The angular position is converted into a standardized high resolution voltage or current output. Measuring ranges 15° to 360° having rising or falling charachteristic are available. Mounting Placement and alignment of the position magnet For non-contact sensor models air gap and alignment of sensor and position magnet has to be observed. The linearity will degrade in case of misalignment. Also external magnetic fields and magnetized materials nearby can effect the measuring result.

If both markings match output will be at 50% of full scale. Accordingly the inclination sensor marking points downward (mounting position see page 14).

Cable screen has to be connected to protective earth. Caution: Observe different color code for pre-assembled accessory cables - refer to accessories pages. The protection class of sensors with connector output is valid only if the electrical plug is connected! Cable outputs must be installed in such a way that no moisture can get into the cable. Crossing the dew point must be avoided.
