E51 Modular Limit Switch Style Sensors
Automation and Control, Inductive Proximity Sensor, High-Performance Limit Switch-Style For Harsh Industrial Applications. High-Performance With Modular, Plug-In Components Provide Application Flexibility, Ease of Maintenance, Less Downtime, And Reduced Inventory.
With the E51 Limit Switch-Style Sensors you can 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.
Standard Sensors—Assembled with Terminal Wiring
Standard E51 sensors feature long sensing ranges and a choice of top or side sensing heads. Alternate frequency units eliminate interference when mounted close to standard frequency units. Order sensors in component form, as assembled plug-in units, or in a sealed version where the sensor body is factory assembled to an epoxy filled receptacle with tamper-proof screws to ensure a lasting seal.
Standard Sensors – Assembled with Receptacles Sensor body is attached to the receptacle with tamper-proof screws.
