Purchase now: Wenglor YK12PA7 Laser Sensor
Purchase now: Atlantech Drives provides you the Wenglor YK12PA7, a specialized Miniature Reflex Sensor utilizing Laser Class 2 (Red) technology. This sensor is famous for its incredible precision in a tiny package. It features Background Suppression with a sensing range of up to 120 mm. The YK12PA7 is specifically designed for applications where space is extremely limited and the target objects are very small, such as detecting IC chips, needle tips, or small mechanical latches.
Technical Specifications and Precision Optics
The YK12PA7 stands out with its High Switching Frequency (approx. 1.9 kHz) and very low current consumption (< 15 mA). The Red Laser spot is razor-sharp, allowing for the detection of height differences as small as 0.5 mm. The sensor uses a 4-pin M8 Connector for a compact footprint. *Note: This product is technically discontinued by the manufacturer, but we source surplus and new-old-stock units for critical repairs.*

Expert Tips: Finding a Replacement
Can’t find a YK12PA7? Expert Tip: Since the YK series is phased out, if you are building a new machine, do not use this. Use the P1KH002 instead. It has the same 120mm range, laser precision, and M8 connector, but with modern IO-Link electronics. If you need the YK12PA7 specifically to fit a custom-molded bracket that won’t fit the P1K housing, contact us for stock availability.
Frequently Asked Questions (FAQs)
Q: Why use a laser here?
A: At 120mm, a standard LED spot would be 10-15mm wide. The YK12PA7 laser spot is under 1mm, allowing you to detect features *inside* a small assembly without triggering on the side walls.
Q: Is it compatible with P1KH mounting?
A: Not exactly. The hole spacing might differ slightly. Always check the dimensional drawing if you are migrating to the P1KH series.
