Long-distance Proximity Sensor
E2EM
CSM_E2EM_DS_E_10_1
Long-distance Proximity Sensor
Long-distance detection at up to 30 mm enables secure mounting
with reduced problems due to workpiece collisions.
No polarity for easy wiring with DC 2-wire models.
Cable protector provided as a standard feature.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read Safety Precautions on
page 6.

Accessories Instruction manual
*1. Use the Sensor within the range in which the setting indicator (green LED) is ON (except X2 Models).
*2. The response frequency is an average value.
Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing distance.
*3. The residual voltage is 5 V. Make sure that the device connected to the Sensor can withstand the residual voltage. (Refer to page 6 for details.)
