Page 5: Safety Instructions
OPD101 2 Safety instructions • The unit described is a subcomponent for integration into a system. – The system architect is responsible for the safety of the system. – The system creator undertakes to perform a risk assessment and to create documentation in accordance with legal and normative requirements to be provided to the operator and user of the system. -
Page 6: Intended Use
OPD101 3 Intended use 3.1 General description The sensor projects a laser line onto the object and determines the height profile of the object along the laser line by means of the triangulation principle. The object to be detected has to be in the sensor's operating range. -
Page 7: Normal Operation
OPD101 In the next step, the sensor continually detects height profiles, compares them to the activated reference profile and generates a matching value. Now the user can set a switching threshold. Interpretation of the matching value (Ò / 7). X axis in [mm]... -
Page 8: Fluctuation Of The Matching Value
OPD101 Matching value provided in [%] Description There is a 50 % match between the measured profile and the activated reference profile. The matching value to be tolerated must be determined by the user during set-up and should be used as switching threshold for the following differentiation:... -
Page 9: Profile Properties
If the value has decreased significantly, e.g. due to changes in the sensor position, it is advisable to teach the object again. The status parameter can be continuously monitored via the ifm parameter setting software “Vision Assistant”. The status parameter can therefore also be used to optimise the sensor position during teaching. -
Page 10: Function
OPD101 4 Function The photoelectric sensor detects the height profile of the object in the operating range, continually or upon triggering, by means of triangulation. Besides, the photoelectric sensor has an IO-Link interface. The sensor can be used in three different modes of operation: •... - Page 11 OPD101 The ifm software package “Vision Assistant” includes a corresponding protocol handler that combines the profile images and visualises them. This simplifies the teaching process (guided teach), as the detection zone of the sensor and the assessment of the profiles is visualised base on the profile images.

OPD101 5 Installation 5.1 Installation conditions u Install the unit so that the object to be detected is within the sensor's detection zone. u For direct installation, fix the unit using two M4 screws. Further accessories Ò www.ifm.com Ò Data sheet Ò Accessories. -
Page 13: Front Inclination
OPD101 5.2.2 Front inclination transmitter receiver interrupted laser line Fig. 5: Front inclination If the sensor is inclined forwards or backwards, make sure that the laser line reflected by the object can be detected by the receiver. It can be ensured that the receiver detects the laser line by reducing the inclination angle or rotating the sensor by 180°. -
