Thermopile Sensor PMMA Plastic Optical Fiber for Sensing Type 2
This is a JINSHANG TECH plastic optical fiber intended for optical sensing and signal pickup, guiding light to and from a sensing head in electrically noisy or space-constrained equipment.
Manufactured for production use rather than as a one-off sample, the unit is built to a stable fiber specification so orders can be repeated with consistent dimensions and performance.
Key Characteristics
- Supply voltage: 60±2 nV/Hz1/2
- Certified to ISO9001 ,ROHS
- Passive sensing tip — no electronics or voltage required at the measurement point
- Immune to EMI and safe around high-voltage and high-noise machinery
- Tight bend radius routes light into compact mechanisms and small enclosures
- High NA for efficient coupling to low-cost LED/phototransistor sensor heads
- Withstands vibration and repeated movement on moving carriages and robots
- Chemically inert polymer tip suitable for damp or corrosive environments
Typical Applications
The unit is commonly used for through-beam and reflective presence/position sensors in machines. The result is a reliable, repeatable build that tolerates the routing, vibration and repeated handling typical of production installations.
Frequently Asked Questions
Q: How is POF used in a sensor? A: Light is launched through the fiber to a sensing head; the returned or interrupted light is measured by a remote amplifier, keeping electronics away from the target.
Q: Can the sensing end be placed near high voltage? A: The fiber is non-conductive, so the sensing tip carries no electrical potential and is safe in high-voltage areas when the amplifier is mounted remotely.
Q: What affects sensing range? A: Fiber diameter, bend radius, head geometry and the amplifier's optical power set the detection distance; larger cores generally collect more light.
Q: Is it affected by motor noise? A: No. Because the signal is light, EMI and RFI from motors, contactors and inverters do not couple into the fiber.
