FAQ
1. What is EE-SPY301?
The EE-SPY301 is a connector-type horizontal reflective photomicrosensor from OMRON, part of the EE-SPY30/40 series. It features a horizontal design with a built-in amplifier, and detects the presence of objects by emitting infrared light and sensing its reflection.
2. What are the key specifications of EE-SPY301?
Key specifications include:
Sensing Method: Reflective (diffuse)
Sensing Distance: 5mm (based on 15×15mm white paper with 90% reflectivity)
Supply Voltage: DC 5V to 24V (wide range)
Output Type: NPN
Output State: Dark-ON
Load Current: 80mA max.
Response Frequency: 100Hz min.
Ingress Protection: IP50
3. What package does EE-SPY301 use?
It uses a through-hole mount module package. It is a horizontal type sensor with dimensions of approximately 26mm (L) × 7mm (W) × 20mm (H) . Electrical connection is made via a dedicated connector.
4. What applications is EE-SPY301 suitable for?
This sensor is widely used in industrial automation for detecting, positioning, and confirming the presence of objects on conveyors, packaging, and assembly lines. Typical applications include product counting on production lines, packaging inspection, automatic door control systems, logistics sorting equipment, robotic vision-assisted positioning, and position detection in automatic assembly equipment. Thanks to its modulated light technology, it is particularly suitable for open factory environments with significant light variations.
5. What development tools support EE-SPY301?
As a standard industrial sensor, it does not require dedicated software tools. It can be directly connected to PLCs (Programmable Logic Controllers), relays, or TTL circuits. A Light-ON indicator is provided for easy on-site adjustment and operation verification. OMRON provides 2D/3D CAD data for this product on their website.
6. What is the operating temperature range of EE-SPY301?
The ambient operating temperature range is -10°C to 55°C (with no freezing or condensation). The storage temperature range is -25°C to 65°C (with no freezing or condensation).
7. What are the key features of EE-SPY301?
Strong Noise Immunity: Uses a modulated light system, effectively resisting interference from ambient light
Wide Voltage Range: Operates on a wide supply voltage of DC 5V to 24V
Easy Setup: Features an optical axis mark for easy alignment and a Light-ON indicator for operation confirmation
High Reliability: Rated IP50 for dust protection
8. Is EE-SPY301 output normally open or normally closed?
The EE-SPY301 has an NPN - Open Collector / Dark-ON output configuration. This means the output turns ON when it does NOT detect an object (dark condition) ; it turns OFF when an object is detected (light condition).
9. What are the alternative models for EE-SPY301?
Within the same series:
EE-SPY302: Vertical mount, 5mm sensing distance, Dark-ON output
EE-SPY401: Horizontal mount, 5mm sensing distance, Light-ON output
EE-SPY402: Vertical mount, 5mm sensing distance, Light-ON output
EE-SPX301: Slot type (through-beam), 3.6mm sensing distance, NPN Dark-ON output
To convert NPN output to PNP, the EE-2001 conversion connector can be used
10. What are the design considerations when using EE-SPY301?
Sensing Object: The rated sensing distance of 5mm is specified for white paper (15×15mm) with 90% reflectivity. The distance will be significantly shorter for black or highly transparent objects
Cable Extension: When extending the cable, use wires with a cross-section of 0.3mm² or more; the total length should be kept under 2 meters; adding an external 10μF capacitor can improve operation stability
External Interference: Avoid exposing the sensor to direct ambient light from fluorescent or incandescent lamps. Receiver surface illumination: incandescent light, sunlight 3000 lx max
Mounting: Connection is made using a connector — do not solder to the pins
