T H E PROXIMITY SWITCHES O F T I E F E N B A C H C O N T R O L S Y S T E M S >>> HAVE BEEN ESPECIALLY DEVELOPED FOR THE RELIABLE, WEAR-FREE AND MAINTENANCE-FREE MEASUREMENT AND EVALUATION OF MOVEMENTS AS INSTRUMENT FOR MONITORING CONVEYOR AND CRANE SYSTEMS, TRANSFER LINES, BELT TRACK; AND MACHINE CONTROLS. The almost inertia-free lnamur-type proximity switches are two-wire sensors and provide an electrically processible signal when actuated. The non-contact position measurement is effected by means of magnets or metallic targets which cause an attenuation of the oscillator when approaching the active sensing surface. Thanks to the use of corrosion-resistant materials the proximity switches are largely unaffected by external influences. They can be installed in any desired position. All proximity switches are certified according to Directive 94/9/EC (ATEX). >>> TIEFENBACH CONTROL SYSTEMS OFFERS OPTIMUM SOLUTIONS FOR THE MOST VARIED MEASUREMENT + EVALUATION OF MOVEMENT APPLICATIONS

ina05/09 FUNCTION AND DESIGN NAMUR proximity switches are two-wire sensors which detect metallic materials without contacting them. Physically, metal approaching the active sensing surface attenuates the oscillator in the proximity switches, that is it decreases the oscillating amplitude. Attenuation is effected by means of metallic targets. The nominal distance stated in the technical data refers to a target made of S235 (St 37) steel. When using other metallic materials reductions of the distance have to be taken into consideration. When the oscillator is attenuated a current change occurs which is identical with the output switching command. For triggering the switching command it is of no importance whether non-metallic materials such as e.g. glass, plastic, or rubber are located between the metallic target and the active sensing surface. Another positive feature of the oscillator is its high degree of safety against interfering pulses. Due to the response time of the proximity switch and particularly of the control device a minimum switching sector length is required which determines the duration of the attenuation. Deattenuation requires a pause sector of at least twice the length. The proximity switches can be used for controlling safety-relevant control and monitoring circuits. The respective criteria are defined in EN 50227 (NAMUR). Irrespective of the status of the control they allow to permanently monitor lines and cables for broken conductors and short circuits. The electronic components are embedded in cast resin. The solid construction with the brass housing ensures adequate safety with respect to explosion protection and mechanical damage. Application The proximity switch can be used in all applications where motions have to be detected and evaluated. It is thus used as control and monitoring organ in conveyor and crane installations, transfer lines, machine control systems, as well as for solving general automation problems. Thanks to its small size it is particularly suitable for speed sensing in gearboxes and other mechanisms with a confined space. It is possible to install the proximity switch flush in metal (shielded). This arrangement, however, already causes an attenuation of the oscillator. Therefore, the switching distance to the metal target has to be reduced.
