Sensors and limit switches

E56 pancake inductive proximity sensors

Tough-built sensor.

These pancake-style sensors are an excellent solution for applications that require an extremely rugged solution combined with the longest inductive sensing ranges available. Eaton's E56 pancake-style sensors feature auto-configurable, complementary outputs for ease of wiring. In addition, power and output LEDs make troubleshooting much easier than conventional sensors.

Core features of E56 pancake inductive proximity sensors

  • Auto-configure output technology on 4-wire DC models automatically detects how the sensor has been wired (NPN or PNP) and automatically sets up the sensor for proper operation without user intervention
  • Small-diameter, 2-wire AC/DC models feature a selector switch inside the housing, enabling output contacts to be used as either NO or NC
  • Range adjustment potentiometers on medium and large diameter units allow for rapid set-up in any machine application
  • The robust design features impact-absorbing potting compound that helps sensors withstand high shock and vibration environments
