The Cutler-Hammer® E56 Pancake

from Eaton’s electrical business is a

high performance inductive proxim-

ity 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, long-

range sensing solution.

Long Range Inductive Sensors Designed for Use in Heavy-Duty

Industrial Environments

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
