描述：The I88-U1Z HW is a 1NO/1NC slow-action insulation-enclosed Limit Switch with steel roller. It has UL94V-0 rated self-extinguishing PA6 enclosure and cover. On actuation, the normally-closed contact functions correspond to the movement of the impact pin. The approach speed controls the contact opening (closing) time. Large distance/actuating travel between normally-closed and normally-open contact function. The switching points are identical in forward and reverse travel. The 6086121021 insulation-enclosed switches the switching elements are integrated directly in the moulded enclosure and are therefore not replaceable (complete switching devices). Galvanic isolation describes the isolation of electrically conducted parts by insulating material or by air gaps. In switching device with several contact elements, galvanically isolated contact elements make it possible to switch voltages with different potential (normally closed contact in safety circuit). . Type-Zb galvanic isolated changeover contact . Snap-on cover can be released with screwdriver . Cover opening range 135° (cover can also be detached from hinge) .
