Approximate price of slow reflection fiber optic sensors

Slow reflection fiber optic sensors typically range from $50 to $300 per unit, depending on specifications, brand, and included amplifier.

Overview

Slow reflection fiber optic sensors, also known as diffuse-reflection or reflective fiber optic sensors, detect objects by measuring the light reflected from a target surface. They are widely used in factory automation, robotics, and harsh environments due to their compact size, flexibility, and immunity to electromagnetic interference . These sensors usually consist of a fiber optic head and a separate amplifier unit, which can affect the overall cost.

Price Range

• Entry-level sensors: Basic reflective fiber optic sensors without advanced features or environmental protection can cost around $50–$100 per unit .
• Mid-range sensors: Units with higher precision, integrated amplifiers, or extended environmental resistance typically range from $100–$200 .
• High-end sensors: Industrial-grade sensors with specialized heads, high-speed response, or extreme temperature tolerance can cost $200–$300 or more . Prices vary based on brand (e.g., Omron, Panasonic, Keyence), fiber length, head material, and amplifier features. Some suppliers, like Farnell UK and Mouser Europe, provide fast quotes and datasheets for specific models . Online marketplaces like Amazon may offer lower-cost options but often lack industrial-grade specifications .

Purchasing Tips

• Check if the sensor includes an amplifier; some heads are sold separately.
• Verify environmental ratings (IP67, temperature range) for your application.
• Compare response time and detection distance, as slow reflection sensors may have longer response times than through-beam types.
• Request supplier quotes for bulk orders or specialized configurations to get accurate pricing. For exact pricing, it is recommended to visit supplier websites such as Mouser, Farnell, or Keyence, where you can select the specific model and configuration to obtain a current quote .
