EE-SA701/801

Pushbutton-type Photomicrosensor
EE-SA701/801
CSM_EE-SA701_801_DS_E_4_2
Using a pushbutton enables
accurately detecting difficult-to-detect
objects.
• Conforms to standards for semiconductor FOUP cassettes to enable
accurately detecting FOUP cassettes without being affected by the
material, color, or reflectance of the bottoms of the cassettes.
• Thin design enables mounting in a wider range of applications, e.g.,
on transfer arms.
• Increased visibility with 4-direction indicator.
• Optical detection of actuator operation provides a long life
(mechanical life: 5 million operations min.).
• Models available with PNP or NPN output.
• Models are available with very flexible robot cable.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.

Note: 1. Free position (FP): The position of the top of the actuator when no force is being applied to the actuator.
Operating position (OP): The position of the top of the actuator when the actuator is pressed and the output transistor changes from OFF to ON for the EESA701-R/-SA701P-R and from ON to OFF for all other models.
Total travel position (TTP): The position of the top of the actuator when the actuator is pressed as far as it can be pressed.
2. This does not indicate that the output will be ON from 3.5 to 4.5 mm, but rather that the output will change from ON to OFF at some point between 3.5 and
4.5 mm.

Operating Principles
This is a pushbutton-type sensor. An emitter (GaAs infrared LED) and
receiver (Si photo IC) are positioned across from each other inside the
sensor and light is received when there is no sensing object. When
the sensing object presses the actuator, the light path between the
emitter and receiver is broken so that the receiver no longer receives
light.
(2) Stability Checking Function
The light intensity emitted by the LED can be reduced by 20% by
using the following circuit configuration. By doing so, the light
reception operation at 80% light intensity with no sensing object
(same as 100%, i.e., the output transistor should turn ON) can be
tested in advance to check for malfunctions caused by deterioration
of LED light intensity.

(1) External Diagnosis Function
The light emission from the LED can be stopped by using the
following circuit configuration. This enables checking the operation of
the receiver by turning the LED ON and OFF when there is no load.

Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
Adjustment
This product is not designed or rated for ensuring
safety of persons either directly or indirectly. Do not
use it for such purposes.
The EE-SA801 requires 10 ms to be in stable operation after power is
supplied. If separate power supplies are used for the EE-SA801 and
load, be sure to supply power to the EE-SA801 before supplying
power to the load.
Precautions for Correct Use
Make sure that the Photomicrosensor is used within the rated ambient
environment conditions.
● Mounting
Mount the Photomicrosensor securely on a flat surface using M3 pan
head screws, and tighten the mounting screws using a tightening
force of 0.59 N·m max.
Operating Environment
• The EE-SA801 is not watertight. Do not use the EE-SA801
outdoors.
• Do not use the EE-SA801 in places where water, oil, or chemical
may be sprayed onto the EE-SA801. The exterior coverings of the
EE-SA801 are made of polycarbonate. Keep the coverings away
from any alkaline, aromatic hydrocarbon, or aliphatic chloride
hydrocarbon solvents, all of which will damage the coverings.
