Product Overview
The Omron EE-SA801A is a pushbutton-type photomicrosensor, manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
The sensor uses a GaAs infrared LED emitter and a silicon photo-IC receiver. Operating position is 3.5 to 4.5 mm with a free position of 5.0 mm and 0 mm total travel. Operating load is 3 N max, 0.5 N typical. It runs from a 12 to 24 VDC supply at 35 mA max and outputs NPN open-collector up to 50 mA with 0.4 V residual.
Response time is 1 ms and the polarity protection diode is built in. Operating temperature is -25 to +55 C. The case is polycarbonate, the actuator is polyacetal, and the 1 m pre-wired cable ends in bare leads. The EE-SA801R is the PNP sibling. For a slot-style optical switch with the same family heritage, pick the EE-SX674.

- Operating position 3.5 to 4.5 mm, free position 5.0 mm, total travel 0 mm max, 3 N max operating load
- 12 to 24 VDC supply, 35 mA max, NPN open-collector output 50 mA / 0.4 V residual, 1 ms response
- 1 m pre-wired standard cable, polycarbonate case, polyacetal actuator, IP40, 16.1 g
- SKU: EE-SA801A
- Series: Omron EE-SA701 / 801 pushbutton photomicrosensor family
- Voltage: 12 TO 24 VDC
Best-Fit Applications
- FOUP cassette seating check on a semiconductor loader where the pushbutton confirms the pod is down regardless of bottom colour or reflectance
- Lightweight tray presence check on a small pick-and-place station where 0.5 N operating load protects the tray from damage
- End-of-arm tool position check on a transfer arm where the 1 ms response catches arrival before the next motion
Buying Checklist
- Pick the EE-SA801A for a pushbutton photomicrosensor with NPN output on 12 to 24 VDC.
- Pick the EE-SA801R instead when the cabinet needs a PNP output instead of NPN.
- Pick the EE-SX674 instead when the line needs a slot-style through-beam optical switch with the same 5 V to 24 V supply range.

FAQ for EE-SA801A
Is the EE-SA801A a fiber amplifier?
No. The EE-SA801A is a pushbutton-type photomicrosensor with a built-in GaAs infrared LED and Si photo-IC. It does not need a fiber cable or external amplifier.
What is the sensing distance of the EE-SA801A?
Output is ON with no load (FP = 5.0 mm). When the actuator is pressed, the output reverses between 3.5 and 4.5 mm. Total travel is 0 mm max.
What cable does the EE-SA801A ship with?
A 1 m pre-wired standard vinyl cable with bare leads on the user end. For a 1 m robot cable, pick the EE-SA701R-R.
Is the EE-SA801A PNP or NPN?
NPN. The EE-SA801R is the PNP sibling with the same housing, supply, and 1 m pre-wired cable.
