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.

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 EE- SA701-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.

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