System Line - AC Single-Stroke Solenoids The AC single-stroke solenoids of the Kendrion „System Line“ are manufactured from magnetically high-quality sheet metals. This design evokes a dynamic force behaviour, the maximum force being reached at the stroke end position. Due to this ascending force characteristic AC single-stroke solenoids are particularly suitable for overcoming spring forces. Compared to the DC single-stroke solenoid higher switching capacities are possible as the switching times are considerably shorter here. In addition, AC single-stroke solenoids with the same performance...

With the AC solenoids of the series WL the yoke is Ushaped while the armature is T-shaped, the pole faces remain blank after grinding in. This design allows for optimum pulling force results with relatively small sizes as the lines of force can pass the working air gap either in the coil centre or via the limbs. The solenoid system can be used for short as well as longer strokes (max. 50 mm). On request further sizes and coil designs are available. With respect to the coil design higher forces can be achieved under consideration of a shorter duty cycle. Pushing models are also available on request....

Special Models on Requeste AC Solenoids Series WLG Solenoid systems of the series WLF have the same design as the type series WL, but they are integrated into a closed aluminum housing providing special protection. This housing allows for particularly effective heat dissipation and use under relatively rough conditions. WLF and WLG have the same design, the only difference being that a bellow ensures a high level of protection against dust. AC Solenoids Series WLA AC solenoids of the series WLA are particularly suitable for use under rough conditions. The excitation system is potted in the housing...

AC Solenoids Series WTI With the series WTI the armature is I-shaped. The socalled plunger-principle is applied here, making this type particularly suitable for large strokes. The solenoid has a very strong acceleration as the stray field is narrow in the starting position. With the immersion of the armature the stray field can develop and the pulling force is reduced until the working air gap has narrowed accordingly. Due to this reduction the working flux dominates and increases the pulling force. Further coil designs are available on request. With respect to the coil design higher forces can...

Technical Explanations As shown in the table below thermal classes are classified according to DIN VDE 0580 / 07.2000 into insulation classes on the basis of their longterm thermal stability. Depending on the type our linear solenoids are manufactured in thermal classes E, B and F. If required by the application most devices can also be delivered in thermal class H. Rated Modes of Operation Continuous operation is the operation during which the duty cycle is so long that the SteadyState temperature is reached. Intermittent operation is the operation during which duty-cycle and currentless break...

Technical Explanations Reset force is the force required to reset the armature into stroke start position after switching off the excitation current. Relative duty cycle (% ED) is the ratio between duty cycle and cycle time in per cent. It is calculate according to the following formula: % ED=(duty cycle / cycle time) * 100 In order to calculate the relative duty cycle the preferred value of the cycle time acc. DIN VDE 0580 item 3.2.2 of 5 minutes is usually taken as a basis. If the cycle time is irregular the relative duty cycle is determined from the ratio between the sum of the duty cycles...
