Overview
The E51DS1 proximity sensor is a compact shielded inductive sensor head designed for industrial motor control and limit detection applications. The E51DS1 is an Eaton Cutler Hammer inductive proximity limit switch with 0.51 inch sensing range with side sensing capability and shielded design for reliable operation in industrial environments. This is a head-only component; a body and receptacle are required to form a complete operating unit.
