概述

Description

EE-SX1046 is a slot-type optoelectronic interrupter (optoswitch) from the EE-SX series. It houses an infrared LED and a phototransistor in a compact package with a narrow slot. When an object passes through the slot, the IR beam is interrupted, causing the phototransistor to switch, giving a digital on/off signal.
Key points:
- Four leads: LED anode/cathode and transistor collector/emitter.
- Output is usually an open-collector transistor; use a pull-up to logic voltage.
- Common uses: rotary encoders, position/speed sensing, printers, robotics.
- Interfaces: drive the LED with a current-limited supply; pull up the transistor output to your logic level.
- Variants exist in different package styles (through-hole and SMD); check the datasheet for exact dimensions, CTR, supply voltages, wavelength, and response times.
For precise electrical specs and mechanical dimensions, consult the EE-SX1046 datasheet.

Features

Here are the typical features of the Panasonic EE-SX1046 (slotted opto-interrupter):
- Slotted optical interrupter with infrared emitter and phototransistor in one compact package
- 4-pin configuration (emitter, detector, Vcc, GND) for easy interfacing
- Outputs a digital signal via an open-collector transistor (requires pull-up)
- Designed for encoder and edge-detection applications; fast switching
- Narrow slot to detect small interrupts from rotating shafts or moving parts
- RoHS compliant and suitable for a wide operating temperature range
- Low profile, suitable for space-constrained designs
Note: exact electrical specs (voltage, current, CTR, response time) vary by variant; consult the datasheet for precise values.

Package

EE-SX1046 is a slot-type optical interrupter (slotted photointerrupter) in a 4-pin through-hole DIP package.

Pinout

- Pin count: 4 pins
- Function: Slotted infrared optointerrupter (IR LED + phototransistor). Pins: 1 = LED anode, 2 = LED cathode, 3 = transistor collector, 4 = transistor emitter.

Manufacturer

Manufacturer: Omron Corporation (Omron).
What kind of company: A Japanese multinational electronics and automation company that designs and manufactures sensors, switches, relays, and other industrial automation components.

Application

EE-SX1046 is a Panasonic optoelectronic sensor for non-contact detection. Common applications:
- Non-contact position sensing and edge detection
- Encoder feedback and speed measurement on motors/conveyors
- Object presence/absence detection
- Counting/indexing in automation lines
- Paper/foil/label detection in printers/scanners
- Replacement for compact limit switches and simple safety interlocks

Equivalent

EE-SX1046 is Sharp’s slotted optical interrupter (emitter + phototransistor). Direct equivalents are other Sharp EE-SX slotted-interrupter parts sharing the same footprint and pinout. For cross‑brand equivalents, look for 4‑pin slotted photointerrupters with the same slot width and similar LED wavelength (~940 nm) and check distributor cross‑reference tables (Omron, Everlight, TT Electronics, etc.).
