The E2A-S08LS02-WP-C1 2M: M8 shielded inductive proximity sensor, 2 mm sensing distance, NPN-NO 3-wire output, 10 V DC supply, IP67 stainless steel housing, LED indicator.
2 mm sensing distance and switching frequency
The 2 mm sensing distance is typical for an M8 shielded inductive sensor — the shield focuses the field so the sensor can be flush-mounted in metal without false triggers from the surrounding material. The 1500 Hz switching frequency is fast enough for counting parts on a conveyor or detecting cam positions on a rotary indexer, but if you need to catch a fast-moving target at higher line speeds, a sensor with a higher switching frequency would be a better fit.
