Power and Output LEDs for Status Indication 3-64 3-65 3-66 3-66 3-67 3-67 The Cutler-Hammer(R) E56 Pancake from Eaton's electrical business is a high performance inductive proximity sensor. The E56 Pancake provides greater sensing ranges than other inductive sensor package types. The E56 Pancake family provides convenience and ease of wiring with auto-configurable, complementary outputs. (Auto-configurable outputs automatically detect an NPN or PNP output configuration and switch the sensor accordingly, without user intervention.) Power and output LEDs make troubleshooting much easier than conventional proximity sensors, which usually only feature output LEDs. These convenience features, combined with the performance of the E56 Pancake, make it an excellent inductive sensing solution for applications requiring an extremely rugged, longrange sensing solution. Approvals Micro-Connector, Mini-Connector or Screw Termination Wiring Options Three Package Sizes with 50, 70 and 100 mm Ranges Product Features Longest inductive sensing ranges available (up to 100 mm) Three sizes to meet your application needs, with maximum ranges of 50, 70 or 100 mm Complementary outputs (1 N.O. / 1 N.C.) on 4-wire DC models Auto-configure output technology on 4-wire DC models, which automatically detect how the sensor has been wired (NPN or PNP) and switch the sensor 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 N.O. or N.C. Robust design featuring vibration and impact-absorbing potting compound Ideal for extreme temperatures or high pressure washdown environments Typical Applications Heavy-duty trucks, cranes and machinery Steel mills Pipe and rod manufacturing Automotive manufacturing Amusement parks Inductive Proximity Sensors E56 Pancake Voltage Type Output Configuration Output Contacts Shielding Sensing Range Connector Style Catalog Number 20 - 250V AC 20 - 60V DC 45/65 Hz -- N.O. or N.C.
