Optical Sensors - Photointerrupters - Slot Type - Logic Output

Definition:
Optical Sensors - Photointerrupters - Slot Type - Logic Output are specialized optoelectronic devices designed to detect the presence or absence of an object within a slot. These sensors consist of an infrared LED emitter and a phototransistor or photodiode receiver aligned opposite each other in a U-shaped housing. When an object interrupts the light beam, the receiver's output switches to a logic-level signal (e.g., TTL or CMOS), making them ideal for digital systems.

Types of Products in This Category:
1. Standard Slot-Type Photointerrupters: Basic models with fixed slot widths and logic-level outputs for general-purpose object detection.
2. High-Precision Models: Designed for applications requiring tight tolerances, such as encoder systems or print machinery.
3. Environment-Resistant Variants: Features like dust-proof or waterproof housings for industrial or outdoor use.
4. Miniature & SMD Versions: Compact designs for space-constrained PCB applications.

Purchasing Recommendations:
- Slot Width: Match the sensor s slot dimensions to the object size for reliable detection.
- Output Logic: Ensure compatibility (e.g., 5V TTL) with your microcontroller or PLC input.
- Response Speed: For high-speed applications (e.g., conveyor belts), select fast-switching models.
- Environmental Factors: Opt for shielded or ruggedized units if exposed to dust, moisture, or vibration.
- Certifications: Check for industry standards (e.g., RoHS, IP ratings) if required.

These sensors are widely used in automation, robotics, and safety systems, offering precise, contactless detection with easy integration into digital circuits.
