E51 inductive proximity sensors

Sensors and limit switches

E51 inductive proximity sensors combine high performance with a familiar limit switch style housing. Modular, plug-in components provide application flexibility, ease of maintenance, less downtime and reduced inventory. Choose from two-wire sensors with AC/DC operation, or four-wire sensors in either AC or DC styles. Connection options include terminal, mini-connector or various lengths of cable. Choose from standard sensors that detect all types of metallic targets.
