Description
The E57 Series is no longer available. Please refer to our
Proximity Sensors
as an alternative
.
The Cutler-Hammer® Premium+ Series
inductive proximity sensors have improved
sensing performance, product durability and
selection. This improved line of sensors
carries the Premium+ Series name because
we have upgraded the design to a rugged
stainless steel body, shock resistant front
caps and impact absorbing potting
compound. Also, the Premium+ Series line
now includes a choice of AC/DC and
DC-only, 12, 18 and 30 mm sensors with
unmatched noise immunity of greater than
20V/meter.

Note:
1 For cable lengths longer than 2m (6'), add the number of the desired length in meters to the end of the listed model number (for model numbers ending with a number, add an "S" and then the length). Example for a 5 m cable: E57LAL12A2 becomes E57LAL12A2S5.
2 Avoid wiring these AC/DC models in series as the sensors may not perform reliably. Contact OMEGA’s Applications Engineering with questions.
