The selection of the sensors is exclusively determined by the need for permanently mounted cables to be installed.

The number of sensors for each door depends of the door width only. In the following drawing, the door width is shown schematically.

A distinction is made between narrow doors, wide doors and extra wide doors. This table provides an overview of the possible door widths:
|
Description of door width |
Explanation |
|
narrow doors door width < 1m(door width < 3'3'') one sensor per door |
Doors that cannot be passed conveniently by two adult persons besides each other at the same time |
|
wide doors 1.0m <= door width < 1.5m (3'3'' <= door width < 4'11'') two sensors per door |
Doors that can be passed conveniently by two adult persons besides each other are considered to be wide. |
|
extra wide doors 1.5m <= door width < 2.0m (4'11" <= door width < 6'6'') three sensors per door |
Doors that can be passed conveniently by three adult persons besides each other are considered to be extra wide. |
Identical sensors are used for narrow, wide and extra wide doors.

When selecting the
location to install the sensors, check that no mechanical parts, such as the
pieces of doors or their supports, are moving in the area vertical below
the passive component of the sensor. |
|
|
When selecting the
location to install the sensors, also check that the sensors will be
installed as close as possible to the vehicle wall. The space
required for the installation of the sensors is shown in the figure on the
right (an optimum is 45mm in height and 50mm in depth). Scale: NTS |
|
|
The sensors are designed symmetrically with regard to their longitudinal axis.Scale: NTS |
|
This allows to install the sensors in two different ways (rotated by 180°):

The sensor arrangement is described by the term element combination
(EC). The element combination includes the information for the software in the
analyser as to
