Inductive Sensors for Extreme Temperature Ranges

These inductive sensors detect contactlessly metallic objects in extreme temperature ranges. With increased switching distances and a very robust design, the sensors are designed for a long service life of several years.

Inductive Sensors with Selective Performance

Inductive sensors with selective performance can differentiate between ferromagnetic metals (e.g. iron or steel) and nonferromagnetic metals (aluminum, brass, copper and stainless steel). The functional principle allows contactless and thus wear-free detection and differentiation of objects.

Inductive Sensors Welding Field Resistant with Correction Factor 1

Sensors in this category detect objects of different metals with identical switching distance. Teflon coating protects the sensor from extreme effects during the welding process. The sensor is also very robust against magnetic direct and alternating fields.

Inductive Sensors with Analog Output

Sensors of this type detect metallic objects and output the distance as a proportional voltage signal, even in dirty environments. The switching distance is identical on different metals, so the correction factor is 1. They also feature an almost linear output voltage.

Inductive Sensors with Full-Metal Housing

Inductive sensors with full-metal housing made of stainless steel 316L (1.4404/316L) are impact-resistant, resistant to chemicals and high water pressure (IP68/IP69K). ATEX approval for 3G and 3D makes these hermetically sealed sensors suitable for applications with a high risk of explosion.

Inductive Sensors with IO-Link

Inductive sensors with IO-Link communicate from the field level to the control. Preventive maintenance is possible via a special diagnosis output. Variable switching distances and frequencies offer a wide range of applications. The sensor output (either PNP or NPN) can be programmed as NC or NO.

Inductive Sensors with Increased Switching Distances

Inductive sensors with increased switching distances offer up to three times the switching distances compared to standard inductive sensors. The integrated weproTec technology ensures fault-free operation of several sensors that are operated directly next to one another.

Inductive Sensors with Standard Switching Distances

Inductive sensors with standard switching distances detect metal objects contactlessly using electromagnetic induction. Thanks to different ranges and different formats and housing materials, they detect the presence of moving parts even in the event of dirt or vibrations.

Temperature Sensors for Contactless Measurement

Sensors of this type measure the temperature of objects contactlessly using infrared radiation – regardless of material, size and state of aggregation. Two switching outputs and an analog output enable the comparison of target/actual values as well as absolute measurements.

Contrast Sensors

Contrast sensors with switching or analog output measure the brightness of objects. Sensors with switching output compare the brightness level with a reference value in order to detect contrast marking, for example. Sensors with analog output provide the measured brightness as a proportional voltage signal in order to monitor brightness curves, for example.

Color Sensors

Color sensors analyze the finest color nuances in automated processes at high speeds and select colored objects based on previously defined reference colors. Thanks to the pulsed white light, the sensors are insensitive to ambient light.

Gloss Sensors

Gloss sensors can differentiate between glossy and matte surfaces.

Fiber-Optic Cables

Plastic or glass fiber-optic cables are flexible enough for use in hard-to-reach places. They are compatible with all fiber-optic cable sensors as well as multispectral color sensors. Sensors with fiber-optic cables are used in scanning mode operation or in through-beam mode.

Fiber-Optic Cable Sensors

Fiber-optic cable sensors are combined with plastic or glass fiber-optic cables and are used in applications with small installation space or high temperatures. The sensors check the presence or position of objects in reflex mode operation or in through beam mode. Up to 15 fiber-optic cables can be connected to the sensors.

Light Curtains

Light curtains operate according to the retro-reflective or through-beam mode and consist of several beams arranged in a row and connected to one another. In industrial use, they are suitable for applications such as pick and place or for measuring tasks such as height or position checks.

Retro-Reflex Sensors with Light Band

Retro-reflex sensors with light band detect objects with variable edges, shapes and sizes. Thanks to the continuous, homogeneous laser light band, the sensor monitors a much larger area than a light barrier with a dot-shaped light spot. The light band can also detect small or translucent parts.

Retro-Reflex Sensors

Reflex light barriers and retro-reflex sensors work with different light sources, whereby the emitter and receiver are located in one housing. When the light beam between the emitter and the defined background or reflector is interrupted, a switching signal is output.

Fork Sensors

Fork sensors work with either red light or a collimated laser light beam. The emitter and receiver are arranged opposite each other in a plastic or stainless steel housing. Fork sensors with collimated laser light beam are particularly effective for detecting the smallest objects or clear glass.

Through-Beam Sensors

Through-beam sensors detect and count small parts, detect the edges of objects and monitor passages in systems. The emitter and receiver are housed in separate housings according to the through-beam mode. The sensor switches as soon as an object interrupts the laser light, red light or infrared light.

Sensors for Roller Conveyor Systems

Sensors for roller conveyor systems detect objects on electrically or pneumatically controlled conveyors. The format is specially adapted to the design of roller conveyors and is therefore safe from mechanical influences. The sensors are available with or without accumulation logic and as reflex sensors or light barriers with a reflector.

Reflex Sensors

In the case of reflex sensors, the emitter and the receiver are located in the same housing. The emitted light is reflected and recorded by the object, the evaluation is carried out according to the energy principle or via angle measurement. Objects can be detected with or without defined background.

Long-Range Laser Distance Sensors

Long-range laser distance sensors work according to the principle of transit time measurement, which means that they cover large working ranges, so that objects can be reliably detected even at great distances. The emitted light can be switched off for these sensors, which eliminates temperature drift.

High-Precision Laser Distance Sensors

High-precision laser distance sensors work according to the principle of angle measurement, whereby color, shape and object surface do not influence the measurement. Depending on the setting, they can be operated at very high speed or resolution. The measuring range can be selected individually within the sensor’s working range.
