Field note — sensor selection
The E2A-S08LS02-M5-B1 is an inductive barrel-style proximity sensor with M8 x 1 thread, 2 mm detection range, PNP output, and 12-24 VDC supply, rated IP67. The 2 mm flush detection suits short-range presence sensing on ferrous metal targets in tight spaces. PNP sourcing output pulls up to the supply rail, so it mates directly with sinking PLC input cards without a pull-up resistor.
