概要

Description

EE-SX4320 is a compact slotted optical switch (photointerrupter) from Omron’s EE-SX family. It combines an infrared LED emitter and a phototransistor receiver in one housing with a narrow slot. When an object passes through the slot, the beam is interrupted and the receiver output changes state. This makes it suitable for position, speed, and encoder-type sensing.
Key points:
- Output: transistor-based (NPN or PNP, often open-collector) and can be configured as dark-on or light-on depending on variant.
- Wiring: usually 3 wires (Vcc, GND, Output) with an appropriate pull-up/down; variants exist with different pinouts.
- Power: typically 5–24 V supply (variant dependent).
- Mounting: requires alignment of the beam with the target and a defined air gap per datasheet.
Common uses: end-stop sensing, gap detection in printers, robotics, and automation.
For exact pinout, voltage, current, and switching characteristics, consult the EE-SX4320 datasheet for your specific variant.

Features

EE-SX4320 is a slotted optical switch (photointerrupter) in the EE-SX family. Typical features include:
- Slotted design with integrated IR emitter and phototransistor receiver for non-contact sensing
- Detects a moving flag/slot through the aperture (no mechanical wear)
- Output: transistor-type (open-collector) NPN or PNP; TTL/CMOS compatible
- Supply voltage: variant-dependent (commonly around 5 V; some variants accept 4.5–24 VDC)
- Fast switching with low power consumption
- Compact, rugged housing suitable for PCB mounting
- Good ambient-light rejection with shielding; some variants offer adjustable sensitivity
- Long life and high reliability due to solid-state construction
- RoHS-compliant variants available; multiple package options (through-hole or surface-mount)
Note: exact electrical specs (voltage range, current, sensitivity) can vary by specific SX4320 variant—check the manufacturer datasheet for precise values.

Package

The EE-SX4320 is a slotted photointerrupter (slot-type photomicrosensor) in a through-hole 4-pin package (slot/photointerrupter housing).

Pinout

EE-SX4320 is a 4-pin slot (photointerrupter) photomicrosensor.
Pins and functions (typical):
- Pin 1: LED anode (V_LED+)
- Pin 2: LED cathode (LED return)
- Pin 3: Phototransistor collector (output — connect to VCC via pull-up)
- Pin 4: Phototransistor emitter (ground)
The detector is an NPN phototransistor; the collector provides the output and needs a pull‑up resistor to VCC. Always confirm the manufacturer datasheet for exact pin numbering orientation and electrical limits.

Manufacturer

Manufacturer: Omron Corporation (specifically Omron Electronic Components).
What kind of company: Omron is a Japanese multinational electronics and automation company that designs and manufactures industrial automation equipment, sensors and electronic components, control systems, and healthcare devices.
