Juli 2005 5:48 17 Miniature Square Inductive Proximity Sensor E2S  Miniature housing with long sensing ranges  Front ans side facing sensing surfaces Features Ultra small housing High-Speed Response 5.5 mm 1 kHz The 5.5 mm x 5.5 mm type permits smaller, space-saving ma- chines and devices. Environment-Resistant Types IP67 Full sealing structure housing, degree of protection IEC60529 IP67. Adopted for more compact machines and devices. Low Current Consumption (Com- 1/20 pared to conventional models) 5.5mm Significantly lower current consumption. The 0.8 mA (for 24 VDC) leakage current for the DC 2-wire type has a ratio of ap- proximately 1/20 compared to the conventional DC 3-wire type. Optimum solution for multiple-sensor applications such as cam switches. E2S D-61 E2S F502-EN2-04.book Seite 62 Dienstag, 26.
