Contrinex 8/10/2018In general, the same application rules as for the well-known inductive switching devices apply. However, there are, in addition, a number of extra features, which are discussed in the application report "New Inductive Proximity Switch with Analog Output".
Contrinex 8/9/2018Safetinex products offer high-quality safeguarding solutions for both personnel and machinery. The range comprises light curtains of Type 2 or 4 according to the international standard ISO 13849. Resolution is suitable to protect hands (30 mm), fingers (14 mm) or full body (3 to 6 beams). A choice of standard or slim profile is available in various lengths up to almost 2 meters.
Contrinex 8/9/2018Contrinex inductive devices work according to one of three different technologies. All involve the generation of an alternating magnetic field that emerges at the sensing face. The presence of a conductive, generally metallic, object influences this field in a way that can be detected and evaluated by built-in electronics. All Contrinex ASIC sensors are IO-Link enabled in PNP NO versions.
Contrinex 8/9/2018Diffuse sensors enjoy great popularity with users and are consequently often employed. With these devices, the pulsed light from the emitting diode falls on an object of any shape or color, from which it is reflected in a diffuse manner. In turn, part of this reflected light reaches the light-receiving device, which is located in the same device (fig.1).
Contrinex 8/9/2018The inductive proximity switches' time came at the beginning of the 1960's. Due to their reliability, high quality to price ratio and ease of installation they have conquered a wide range of applications. Despite many technical improvements, one of the substantial and long standing drawbacks of these devices was the poor ratio of construction size to switching distance.
Contrinex 8/9/2018The ideal detector should be as precise as you want and infinitely fast, but close to zero in price and size. We will show in the following text first of all what it is possible to achieve today regarding size. Due to the ever-increasing intensive use of high-performance electronic machine controls, a larger concentration of sensors can be observed.
Contrinex 8/9/2018Classical (switching) inductive proximity switches in fact work internally as analog devices, although they produce a binary signal at the output, which is often desired. A large part of the available internal information, though, is lost. Switches with analog outputs provide the user with full information, permitting a variety of possible applications.
Contrinex 8/9/2018Pressure-resistant inductive proximity switches were developed for a multitude of uses: from all applications in the area of hydraulic technology to many uses within the domain of pressure (up to 500 bars). Pressure resistance of the switch is dependent on the thickness of the casing walls particularly in the region of the sensing face. Herein lies a problem: to guarantee an acceptable switching distance with these thicker walls.
Contrinex 8/9/2018Cylindrical housings are preferred for smaller sensors. Sizes M18, M12 and M8 are at present available on the market for photoelectric equipment (versions in non-standard housings such as M6 and others with separate evaluation electronics are not discussed here). Required, but still not available, were units with a 4 mm diameter or with MS thread and which are known from inductive versions and used there in large numbers.
Contrinex 8/8/2018In principle, Condet devices give approximately the same operating distances on non-ferrous metals as on steel (with standard devices, an important reduction must be reckoned with on non-ferrous metals). The correction factor is, however, not exactly 1 (table 1). It is, moreover, dependent on the device's size, execution (embeddable I non-embeddable) and the target geometry (dimensions and thickness).
Contrinex 8/8/2018Contrinex now offers inductive proximity switches which function using the completely new Condet technology the conducting target, provoking a current flow. When the transmitter current pulse is abruptly switched off, the object becomes the primary coil. The residual current flowing in it at that moment fades away, thereby inducing a voltage in the device coil, which is now the secondary coil (Fig.2). This reverse induced voltage is evaluated by the device.
Contrinex 8/8/2018Contrinex Basic range inductive sensors have a worldwide and well-deserved reputation for uncompromising accuracy and exceptional reliability. With best-in-class sensing distances between 1.5 mm and 40 mm, the Basic range offers fit-and-forget operation, delivering world-class performance and a highly attractive total cost of ownership.
Contrinex 8/8/2018Contrinex photoelectric devices are divided into five technology families, depending on their operating principle. The program includes energetic diffuse sensors, diffuse sensors with background suppression, reflex sensors, through-beam sensors and sensors with analog output.
Contrinex 8/8/2018Compared to classic systems, such as bar codes or laser marking, RFID technology offers important advantages. Transponder information can be read or written even when there is no direct line of sight between it and the Read/Write Module. In addition, information can be added, modified or replaced. It is a useful technology for automated production, reducing human error while increasing reliability, flexibility and traceability.
Contrinex 4/16/2018The sensing face of the proximity switch can be located in the same plane as the metallic mounting surface (naturally, it may also protrude if so desired). The mounting surface is allowed to fit tightly around the device; it may for instance also have a tapped fixing thread.
Contrinex 4/16/2018Today, encoders are mature products, and are available in a variety of designs. However, compared to inductive proximity switches, they are significantly more expensive. In addition, they have rotating axes, and consequently require a certain care during assembly. Finally, encoders are often far too efficient for the requirements of the job to be done.
Contrinex 10/9/2014Intelligent sensors are the fundamental building blocks of modern smart factories. They enable sensor-supported production resources (machines, robots, etc.) to configure, control, manage and optimize themselves. Precise, reliable sensor data is now more essential than ever.
