What are the key features of EE-SX493?
- 2 mm slot gap transmissive optical sensor integrates an IR emitter and photo-IC detector in a single compact housing for simple installation
- Photo-IC output delivers TTL-compatible logic levels directly, eliminating the need for external comparator or pull-up circuitry in most microcontroller interfaces
- Compact slot-type package with mounting holes enables secure mechanical fixing on motor shafts, conveyor edges, and encoder wheels for reliable position sensing
What is EE-SX493 used for?
The EE-SX493 is used in factory automation equipment to detect the position or speed of rotating encoder disks, conveyor belts, and actuator limit positions through its 2 mm optical slot. The integrated photo-IC output interfaces directly with PLCs and microcontrollers at 5 V logic levels without additional signal-conditioning components. Its rugged slot housing suits end-of-travel detection in printers, copiers, and robotic arms where reliable non-contact switching is required.

Frequently Asked Questions
How does the 2 mm slot gap of the EE-SX493 constrain the maximum thickness of detectable objects such as encoder wheels or flags?
The 2 mm slot gap sets the maximum allowable thickness of any interrupter flag or encoder disk passing through the sensor. Objects thicker than 2 mm will contact the housing and cannot pass, so designers must use flags or chopper wheels with blade thickness under 1.5 mm to allow adequate clearance. For thicker interrupters, Omron offers wider-slot variants with gaps of 3 mm or 5 mm in the EE-SX series.
Does the EE-SX493 photo-IC output connect directly to a 3.3 V microcontroller GPIO without additional circuitry?
The EE-SX493 photo-IC output is specified for a 5 V supply and provides TTL-compatible logic levels (logic-low typically below 0.4 V, logic-high close to Vcc). Connecting it directly to a 3.3 V GPIO input may work if the input is 5 V-tolerant, but for strict 3.3 V systems, a voltage divider or level-shift resistor of around 1 kΩ to 10 kΩ is recommended to prevent exceeding the GPIO absolute maximum voltage rating.
In what industrial automation scenarios does the EE-SX493 offer advantages over a reflective photoelectric sensor?
Transmissive sensors like the EE-SX493 are immune to surface color or reflectivity variations of the target object, making them more reliable than reflective sensors for detecting transparent films, clear packaging, or shiny metal tabs. The 2 mm slot provides a defined optical path that is unaffected by ambient light from the side, enabling consistent detection in environments with fluctuating background illumination common in 24/7 manufacturing lines.
