3.1

pressure-sensitive mat

sensitive protective equipment (ISO 12100:2010, 3.28.5) comprising a sensor (3.3) or sensors, a control unit (3.5) and one or more one or more output signal switching devices (3.6) which detects a person standing on it or who steps onto it and where the effective sensing area (3.4) is deformed locally when the sensor(s) is actuated

Note 1 to entry: See Figure 1 for a schematic sketch of a pressure-sensitive mat.

3.2

pressure-sensitive floor

sensitive protective equipment (ISO 12100:2010, 3.28.5) comprising a sensor (3.3) or sensors, a control unit (3.5) and one or more output signal switching devices (3.6) which detects a person standing on it or who steps onto it and where the effective sensing area (3.4) is moved as a whole when the sensor(s) is actuated

Note 1 to entry: See Figure 1 for a schematic sketch of a pressure-sensitive floor.

3.3

sensor

part of the pressure-sensitive mat (3.1) or pressure-sensitive floor (3.2) which contains an effective sensing area (3.4)

Note 1 to entry: The application of an actuating force to the effective sensing area causes the signal from the sensor to the control unit to change its state.

3.4

effective sensing area

part of the top surface area of the sensor (3.3) or a combination of sensors of the pressure-sensitive mat (3.1) or pressure-sensitive floor (3.2) within which a response to an actuating force will take place

Note 1 to entry: See 4.2 for requirements with regard to the actuating force.

3.5

control unit

device that responds to the condition of the sensor (3.3) and controls the state of the output signal switching device (3.6)

Note 1 to entry: The control unit can also monitor the integrity of the pressure-sensitive mat or pressure-sensitive floor (see reference to categories and performance levels according to ISO 13849‑1) and can contain facilities for processing a reset signal. The control unit can be integrated with the machine control system.

3.6

output signal switching device

part of the pressure-sensitive mat (3.1) or pressure-sensitive floor (3.2) which responds by producing an OFF state when the sensor (3.3) or monitoring function means is actuated

Note 1 to entry: The output signal switching device can be integrated with the machine control system.

3.7

actuating force

any force which produces a pressure on the effective sensing area (3.4) to create an OFF state in the output signal switching device (3.6)

3.8

reset

function which permits an ON state in the output signal switching device (3.6) , providing that certain conditions are met

3.9

ON state

state in which the output circuit(s) of an output signal switching device (3.6) is complete and permits the flow of current or fluid

3.10

OFF state

state in which the output circuit or circuits of an output signal switching device (3.6) are broken and interrupt the flow of current or fluid

3.11

response time

time between the start of the application of a force to the effective sensing area (3.4) and the start of the OFF state of the output signal switching device (3.6)

Note 1 to entry: See 4.3 for requirements with regard to the response time.

3.12

dead zone

part of the top surface area of the sensor (3.3) outside the effective sensing area (3.4)
