Built sensor tough E52 rectangular style – Eaton's E52 rectangular-style inductive proximity sensors feature a compact, space-saving design for applications where tubular sensors cannot be used. These 3-wire DC devices are constructed with robust PBT housings for corrosion resistance, and they are epoxy filled to withstand shock and vibration. Bright indicator LEDs are available on all models to clearly show sensor status. E52 cube style – Eaton’s E52 cube-style sensors deliver rugged, robust, long-range inductive sensing. These sensors feature convenient auto-con?guring outputs that automatically detect an NPN or PNP output con?guration and automatically set up the sensor for proper operation, without user intervention. Bright power and output indicator LEDs make setup and troubleshooting easy.
