Unshielded vs. shielded – what the sensing distance means for fit
The E2B-M18KN16-M1-C1: Unshielded construction gives this sensor 16 mm of sensing range – three times more than the shielded peer E2B-M18KS05-M1-B1 (5 mm). The trade-off: unshielded sensors require non-flush mounting (at least the sensing distance away from ferrous metal framing). If your application can tolerate that stand-off, the longer range buys more margin against target wobble or contamination.
