EE-SX1340

EE-SX1340 is a model in Omron’s EE-SX family of compact optical sensors. It’s a small infrared photoelectric switch that detects objects without contact. The device combines an IR emitter and a receiver in one housing and switches its output when the light path is interrupted or reflected by a target. It typically provides a digital switching output (NPN or PNP open-collector) from a DC supply (commonly 5–24 V). SX1340 variants come in 3-wire or 4-wire configurations and may offer dark- or light-ON operation with basic sensitivity adjustments on some versions. Applications include printers, packaging lines, conveyors, and general part detection. For exact sensing distance, output type, LED current, mounting, and other specs, consult the EE-SX1340 datasheet.

EE-SX1340 is Omron’s EE-SX series slotted optical interrupter. Key features:
- Slotted package with integrated IR LED and phototransistor
- Detects object presence by interrupting light through the slot
- Digital output via transistor switch (typical NPN open-collector or similar)
- Compatible with standard DC supplies (variants commonly around 5 V; some versions support wider ranges)
- Low power consumption and fast switching
- Compact, robust housing; suitable for through-hole or PCB mounting
- Numerous slot/lead options for easy mechanical integration
- Used for encoders, printers, edge/position sensing, and other counting/detection tasks
- Generally offers good immunity to ambient light with built-in filtering
Note: exact electrical specifications (voltage range, current, response time, and output type) vary by specific variant; verify the datasheet for the SX1340 variant you’re using.

Pin count: 4 pins.
Function: Slotted optical interrupter (photo-interrupter). It contains an IR emitter LED and a phototransistor. Pins are LED Anode, LED Cathode, Phototransistor Collector, and Phototransistor Emitter.
