Position Sensors
For non-contact position sensing: an extensive variety of inductive, capacitive, magnetic and photoelectric sensors.
Inductive Sensors

Inductive sensors are nowadays indispensable for industrial usage. As compared to mechanical switches they offer almost ideal conditions: non-contact operation free from any wear and tear, high switching frequencies and accuracy. In addition, they are insensitive to vibration, dust and moisture. Inductive sensors detect all metals without contact.

Capacitive Sensors

Capacitive sensors are used for the non-contact detection of any objects. In contrast to inductive sensors, which only detect metallic objects, capacitive sensors can also detect non-metallic materials. Typical applications are in the wood, paper, glass, plastic, food and chemical industries.

Magnetic Sensors

Magnetic sensors are used for the detection of positions without contact or wear and tear in control technology. They are used where inductive proximity switches reach their limits. Since magnetic fields penetrate all non-magnetizable materials, the sensors can detect magnets through walls made of non-ferrous metal, stainless steel, aluminum, plastic or wood.

Cylinder Sensors

Non-contact sensors virtually work without wear and often achieve a longer life than Reed switches. This saves expensive repair and downtimes.

Photoelectric Sensors For General Applications

Photoelectric sensors are used where safe and non-contact de-tection of the exact position of objects is required. The material of the objects to be detected is of no importance. Compared to proximity switches photoelectric sensors have a much higher sensing zone.

Photoelectric Fork Sensors / Angle Sensors

As is the case with through-beam sensors transmitter and receiver are arranged face to face. Both components are permanent parts of a fork or an angle, i.e. they do not have to be aligned towards each other.If an object enters the detection zone, the light beam is interrupted and a switching signal is generated. Optical fork and angle sensors use a particularly fine light beam and are thus suitable for the detection of tiny objects.

Laser Sensors / Distance Measurement Sensors

Laser systems are used where detection of small objects or precise positioning is required.Due to the small angle of divergence long ranges of up to 60 meters can be achieved.

Fibre Optic Sensors

Fibre optics are used where mounting space for photoelectric standard sensors is confined. Advantages of these systems: The evaluation electronics and the optoelectronic components are located separately from the sensing surface of the system.Fibre optic sensing heads can therefore be mounted in places where access is difficult.

Photoelectric Sensors For Specific Applications

Special tasks require special solutions. In addition to the standard photoelectric sensors and fibre optic systems ifm electronic offers special sensors for certain applications.

Feedback Systems For Valves And Valve Actuators

ifm electronic offers two inductive sensors integrated into one housing for position feedback on quarter-turn actuators (type IND). A target puck with two targets offset by 90° which is installed on the actuator shaft damps the lower or upper sensor of the IND depending on the position of the actuator (“open” or “closed). For position feedback on rising stem valves efector valvis is used. Two or three optional switch points can be set via a pushbutton over a stroke of 80 mm. This measuring stroke is resolved into steps of 0.2 mm by means of a target mounted on the valve spindle. Using this inductive sensor enables the detection of even very short strokes.

Switching Amplifiers

Switching amplifiers evaluate the sensor’s signal and control the output. Variants with relay as well as active transistor and potential-free optocoupler outputs are available.


Sensors For Motion Control
Detection of movement – from encoders, rotational speed detection through to pulse evaluation, with 100% quality.

Encoders use the wear-free photoelectric detection. A pulse disc firmly attached to the shaft ensures this detection.By means of high pulse counts linear distances can be precisely resolved to just a few millimetres.

Speed Sensors

Rotational speed sensors integrate rotational speed detection and monitoring in one unit. The sensor head operates to the principle of the inductive proximity sensor. The sensor detects metal actuating surfaces on a rotating machine. The integrated evaluation converts this information into rotational speed. If the set min/max rotational speed is higher or lower, the electronic output switches.

Inclination Sensors

The 2-axis inclination sensors with a built-in CAN open interface are used for leveling and angular position detection of mobile machines. Typical applications are for example position detection of platforms or leveling of mobile cranes. Moreover there are inclination sensors with binary or analogue output stages which are connected directly to controllers or I/O modules.

Pulse Evaluation Systems

The complete product family includes analogue and digital pulse evaluation systems for speed, slip and direction monitoring, frequency-to-current converters, counters and digital displays as well as threshold relays and displays for analogue standard signals.

Vision Sensors

Stand-alone unit with integrated lighting and evaluation in a robust, industrially compatible housing. The electronic eye for monitoring presence, completeness, position, quality control as well as sorting tasks.

3D Sensors

efector pmd 3d is the first industrial 3D sensor that can assess objects in three dimensions at a glance. Each pixel of this chip matrix evaluates its distance to the object. The image of the object on the chip matrix and the respective distance values correspond to a 3D image. The integrated evaluation enables the detailed assessment of the object’s or scene’s conditions by means of volume, distance or level detection in three dimensions.

3D Cameras

The pmd 3d camera detects scenes and objects in their spatial dimensions at a glance. In contrast to laser scanners it does not require moving components and is thus robust and wear-free. The operating principle is the same as for the 3D sensor. Besides the 3D distance image the camera provides a grey image of the scene. The combination of these images offers the possibility to freely program application-specific tasks by means of a software development kit.

Level Sensors

Level measurement distinguishes between direct measurement in the medium and the indirect detection from the outside (for example through the tank wall by means of capacitive sensors)deposits and wear and tear often lead to failures in particular if mechanical switches are in contact with the medium.The electronic IFM sensors however can do without any mechanical component. This makes the sensors especially robust and reliable. Regular maintenance and cleaning are not necessary.

Temperature Sensors

In automation and process technology, monitoring and control of temperatures is one of the most important measuring tasks. The correct temperature often influences quality and efficiency of the process. To avoid dangerous states, the temperature must be monitored in many applications.To do so, compact temperature switches and transmitters as well as cable and probe sensors are used that are connected to an external control monitor. In some industrial areas non-contact infrared (IR) measuring sensors are used.

Signal Evaluation Systems

Control monitors in DC and AC versions evaluate the signals of the flow sensors and provide them as a binary signal for further processing. They integrate wire break and temperature monitoring. Versions for hazardous areas are also available.
