What it is
The XUYAFPCO946S is a Telemecanique fiber-optic photoelectric sensor in the Photoelectric Sensors class, listed under the Square D Switches & Sensors brand. Fiber-optic photoelectric sensors are used for object detection and counting on automation lines where space is tight, the target is small, or the sensing environment is harsh — the fiber cable carries the light to and from the detection point so the amplifier electronics can sit in the panel away from heat, moisture, or mechanical abuse.
Lifecycle and sourcing
Lifecycle stage is recorded as current, so the part is specified into the BOM rather than routed through a last-time-buy or surplus channel. UPC 389119010002 supports PO and nameplate traceability for the storeroom record. Submit the line against an RFQ for current pricing and lead time; ratings beyond identity are not on this ledger entry, so the datasheet governs optical range, fiber length, and output configuration at order time.
