Long-distance Proximity Sensor
Safe Mounting with Greater Sensing
Distance and Easy Wiring with No
Polarity
Ensures a sensing distance approximately 1.5 to 2
times larger than that of any conventional OMRON
Sensor.
Offers greater design flexibility and ease for the
detection of large-sized or non-ferrous sensing
objects.
Problems such as the collision of workpieces are
eliminated.
The E2EM has no polarity, thus eliminating
problems associated with reversed wiring.
