描述：The I88-SU1Z HW is a 1NO/1NC snap-action insulation-enclosed Limit Switch with steel roller. It has UL94V-0 rated self-extinguishing black PA6 enclosure and cover. On actuation, the normally-closed contact function is immediately followed by the normally-open contact function. In this configuration there is no overlap of the NC/NO contacts. The switch provides a distinct OR-function. The changeover accuracy is not dependent on the approach speed. Consistently effective suppression of DC arc. Reliable contact-making also for extremely slow approach speeds. The snap mechanism triggers the full opening width of the contact on reaching the changeover point. Due to the force reversal in the mechanical system, a different switching point occurs in forward and reverse travel. The lag is referred to as hysteresis. The 6086171022 insulation-enclosed switches the switching elements are integrated directly in the moulded enclosure and are therefore not replaceable (complete switching devices). .
