TPS

2. Introduction

The sensors of the TPS product family are a class of very
precise active infrared proximity sensors with background
suppression. Due to their very high sensitivity, they are able
to operate over distances of up to 2 m for independent
targets. The two sensor beams are in the same housing.
This unique concept allows various applications, such as
reliable object detection, direction recognition of moving
objects, height discrimination, etc. These applications
would not easily be possible with two individual sensors.
The sensing range can be adjusted very precisely by
multiturn potentiometers between 0.3 m and 2 m. The
two integrated status LEDs allow simple trigger level
adjustment.
The detection principle is based on triangulation
technology. This technology is optimized for excellent
background suppression and low sensitivity variation
between black and white objects. Therefore, the TPS
sensor is independent to variable ambient light conditions.
The application of multiple (adjacent) TPS sensors requires
only a gap of 0.2 m between the devices and 0.1 m to the
wall (see Figure 6).
IMPORTANT
 The infrared beams are not visible to the
human eye and are completely safe.

3. Applications

The TPS sensor uses the two light beams in different ways.
3.1

TPS 100: Presence detection

Figure 1: Function of TPS 100
If an object interrupts either beam, one shared output is
switched. The trigger level can be adjusted according to
the application requirements. The sensor can be tested
with a simple pulse using the test input.Closing edge of

TPS 200: Level detection

Figure 2: Function of TPS 200
With individually adjusted trigger levels on each beam,
the unit detects objects of different height. Each of the two
outputs represents the status of one beam with its related
trigger level.

TPS 210: Direction recognition

Figure 3: Function of TPS 210
The unit recognizes the direction of passing objects and
sends a pulse to the corresponding output.
