E2S
Miniature Square Inductive Proximity Sensor
E2S
• Miniature housing with long sensing ranges
• Front ans side facing sensing surfaces
Features
The 5.5 mm x 5.5 mm type permits smaller, space-saving ma-
chines and devices.
Full sealing structure housing, degree of protection IEC60529 IP67.
Significantly lower current consumption. The 0.8 mA (for 24
VDC) leakage current for the DC 2-wire type has a ratio of ap-
proximately 1/20 compared to the conventional DC 3-wire
type. Optimum solution for multiple-sensor applications such
as cam switches.

Rating/Performance
DC 2-wire Models
* The response frequencies for DC switching are average values measured under the condition that the distance between each sensing object is twice as large as the
size of the sensing object and the sensing distance set is half of the maximum sensing distance.
DC 3-wire Models
* The response frequencies for DC switching are average values measured under the condition that the distance between each sensing object is twice as large as the
size of the sensing object and the sensing distance set is half of the maximum sensing distance.

Precautions
Design
Effects of Surrounding Metal
• Provide a minimum distance between the Sensor and the
surrounding metal as shown in the table below.
• Front Surface Sensing Type (Not exceeding the sensor
head height)
(Unit: mm)
• End Surface Sensing Type
(Unit: mm)
Mutual Interference
If more than one Sensor is located face to face or in parallel,
be sure to maintain enough space between adjacent Sensors
to suppress mutual interference as provided in the following
diagram,.
(Unit: mm)
Note: The above values in parentheses are applicable when using two sensors
with different frequencies.
Mounting
Tightening torgues
Do not tighten the E2S-W(Q)2#mounting screws to a torque
exceeding 0.7 Nm.
