BFKK PZ-101 Photoelectric Sensor

SKU CH-R5RH-SAR6D

A built-in amplifier photoelectric sensor with a visible red LED spot for precise alignment up to 100 mm

  • Product typeSensors
  • Visible red LED spot simplifies alignment
  • 5 × 5 mm beam spot enables precise detection
  • 0–100 mm range suits close-range sensing
  • Built-in amplifier reduces external wiring
  • New condition ensures full manufacturer performance

Compact Spot Detection

The BFKK PZ-101 photoelectric sensor integrates an amplifier and a special lens to produce a small, focused beam spot. A red LED source makes the detection point visible for quick alignment during setup. It suits automation tasks that require precise, short-range presence sensing.

Operating Range

The unit detects targets from direct contact out to 100 mm with a visible spot as small as 5 x 5 mm at close range. The built-in amplifier eliminates the need for a separate controller, simplifying wiring and reducing panel space. Red LED emission allows operators to verify beam placement by eye.

Integration Fit

As a self-contained sensor, it requires only a power connection and an output line to the control system. The visible beam removes guesswork when positioning the unit relative to conveyors, feeders or pick-and-place heads. Buyers needing longer sensing distances or through-beam configurations should consider alternative architectures.

Questions about this item

How do I align the sensor using the visible red LED spot?

Position the sensor so the red LED projects a 5 x 5 mm spot on the target within 0 to 100 mm range; the visible beam lets you confirm exact alignment before tightening the mount.

What maintenance does the built-in amplifier photoelectric sensor require?

Periodically clean the lens to keep the 5 x 5 mm spot sharp; the red LED source has no user-replaceable parts, so only optical surface care is needed.

At what distance does the detectable spot size start to exceed the specified 5 x 5 mm?

The 5 x 5 mm spot is quoted at the sensor face; beyond the 100 mm maximum range the beam diverges and reliable detection drops off.
