1 Generalinformaon
The ASO SENTIR bumper is cer  ed according to “Safety of machinery — Pressure sensi ve protec ve devices —Part 3:
General principles for design and tes ng of pressure-sensi ve bumpers, plates, wires and similar devices”.
For the determina on of the performance level on a safety bumper, the overall system of the machine has to be determined
according to a previous risk assessment. The moun ng posi on can be chosen variably. But make sure the safety bumper is
not damaged. A er moun ng a func oning test should be made.
2 Theconstrucon
The basic construc on of the safety contact bumper consists out of a foam core and a one piece extruded signal generator
sensor, with two contact elements located opposite each other, which are assembled on an aluminium pro le.
The coa ng of the SENTIR bumper consists of imia on leather.
When the SENTIR bumper is compressed and the sensor is actuated, the evalua on device sends an immediate command to
the control unit.
Cable break is monitored permanently by an addi onal evalua on electronic (ELMON safety relay, e.g.).

5.1 Dimensioningofbumperheight
Use the following key in order to determine the appropriate height for the bumper:
Actuangdistance:  sB=15%bumperheight
Overtraveldistance:  sV=60%bumperheight
Nolongercompressiblebumper: 25%bumperheight
The overtravel distance sV can then be used to determine the appropriate bumper height.
Average values by a test speed of 10 mm/s.
These data are reference values compiled by laboratory tests. Even if the component is used as intended, external factors
and reac on  mes of all system components can have an infl uence on this type of value. Taking into account a risk analysis
of the machine to be carried out, the applica on of this safety component thus allows a presump on of conformity, but
does not release the machine manufacturer from the obliga on to carry out an applica on-side test in order to demonstrate
compliance with all applicable standards and direc ves.
