Optical Sensors - Photointerrupters - Slot Type - Transistor Output
Definition:
Optical Sensors - Photointerrupters - Slot Type - Transistor Output are specialized optoelectronic devices designed to detect the presence, absence, or movement of objects within a predefined slot. These sensors consist of an infrared LED emitter and a phototransistor receiver aligned opposite each other in a compact housing. When an object interrupts the light beam passing through the slot, the transistor output switches states, providing a reliable digital signal for detection applications.
Types & Variations:
This category includes multiple configurations tailored for diverse industrial and commercial needs:
- Slot Width Variations: Ranging from narrow (e.g., 3mm) to wide (e.g., 20mm) slots for different object sizes.
- Output Types: Transistor output (NPN/PNP) for compatibility with PLCs, microcontrollers, or logic circuits.
- Packaging Options: Through-hole or surface-mount designs for PCB integration.
- Performance Grades: Standard vs. high-precision models with varying response times and sensing accuracy.
Purchasing Recommendations:
1. Application Alignment: Select slot width based on object size and required detection precision. For automated assembly lines, opt for sub-millimeter tolerance models.
2. Output Compatibility: Verify voltage/current ratings (e.g., 5V DC, 20mA) to match your control system. NPN outputs are common for sinking configurations.
3. Environmental Fit: For harsh environments (dust, moisture), prioritize IP-rated housings or models with reinforced IR filtering.
4. Certifications: Ensure compliance with industry standards (e.g., RoHS, CE) for quality assurance.
Ideal for robotics, security systems, and industrial automation, these sensors offer cost-effective, non-contact detection with minimal maintenance. Compare datasheet parameters (e.g., response time, gap distance) to optimize performance-to-price ratios.
