What the ratings mean for fit
The E2E-X1C1 2M: The 1 mm sensing distance is the flush-mount (shielded) reach — if the target is non-ferrous (aluminum, brass), expect that distance to shrink; the sensor is specified for ferrous metal only. The 0 to 0.7 mm set distance range gives you fine adjustment for repeatable detection of small parts. Red LED indicator confirms target presence at a glance, useful during commissioning or troubleshooting without a scope. Response speed of 3 kHz means the sensor can detect objects passing at up to 3,000 events per second — adequate for counting on a fast indexing line or timing a cam position. The 15% max differential travel (hysteresis) prevents chatter at the switching threshold. Protection circuits include reverse polarity and surge suppression, so a miswire or transient on the DC rail won't kill the sensor on the first fault. Operating and storage temperature range is –25°C to 70°C with no icing or condensation — rated for indoor industrial environments but not for freezers or outdoor exposure without a heated enclosure. Ambient humidity tolerance is 35% to 95%, so it handles washdown zones if the cable entry is sealed. The 2 m cable is pre-wired; no connector option here, so factor in a junction box or terminal strip at the sensor location.
