Note ) As the external shock absorber, a unit with appropriate capacity and features should be installed close to the load center of gravity. Note ) The selection confirmation is extremely important with this series. The selection should be confirmed thoroughly according to the selection flow on page.

Refer to each graph on page regarding the maximum allowable moment and maximum load weight for a particular piston speed. Precautions on design Prior to the selection calculation, verify the conformity of the operating conditions, such as the use of an external guide (in case of connection with a floating mechanism bracket, for example) or a stroke adjusting unit, with the maximum operating speed. (Refer to page.) Load weight (kg) m Moment (Nm) m m F M=F L F M=F L F M=F L L L L Calculation of guide load factor. Maximum load weight (), static moment (), and dynamic moment () (at the time of impact with stopper) must be examined for the selection calculations. To evaluate, use υa (average speed) for () and (), and υ (impact speed υ =.υa) for (). Calculate m max for () from the maximum allowable load graph (m, m, m ) and Mmax for () and () from the maximum allowable moment graph (M, M, M).

Note ) Moment caused by the impact load equivalent at the stroke end (at the time of impact with stopper). Note ) Depending on the shape of the work piece, multiple moments may occur. When this happens, the sum of the load factors (Σα) is the total of all such moments..

In conjunction with the absorption capacity selection, however, also confirm the conditions which make the shock absorber collision impact force to stay within the allowable range in the graph. Use of an external shock absorber with conditions exceeding the allowable range may damage the cylinder. To confirm the collision impact force of the shock absorber, first find the impact force or acceleration under the operating conditions using the selection information or selection software provided by the manufacturer, and then refer to the graph.

Switch Switch Black [White] Black [White] Blue [Black] Load -wire with -switch AND connection Switch Switch Brown [Red] Load When two switches are connected in series, a load may malfunction because the load voltage will decline when in the ON state. The indicator lights will light when both switches are in the ON state. Load voltage at ON = Power supply voltage Internal voltage drop pcs. = V V pcs. = V Example: Power supply is VDC Internal voltage drop in switch is V. -wire with -switch OR connection < Solid State> < Reed Switch> Brown [Red] Switch Switch Blue [Black] Brown [Red] Load When two switches are connected in parallel, malfunction may occur because the load voltage will increase when in the OFF state. Load voltage at OFF = Leakage current pcs. Load impedance = ma kω =6 V Example: Load impedance is kω. Leakage current from switch is ma. Because there is no current leakage, the load voltage will not increase when turned OFF However, depending on the number of switches in the ON state, the indicator lights may sometimes grow dim or not light up because of the dispersion and reduction of the current flowing to the switches.
