The XUK5APANM12 is a diffuse-mode photoelectric sensor from the Square D Telemecanique XUK block series. It detects objects directly up to 1 m away without a separate reflector, switching a PNP output at 100 mA into a 12–24 VDC supply. Response time is 2 ms with on/off delay and solid-state output options, and the sensor operates at up to 250 Hz. The 4-pin micro DC connector mates with standard M12 cordsets, so field replacement doesn't require stripping cable. Rated NEMA 4/4X/12/13 and IP65, the PBT housing withstands washdown zones and indoor environments. The yellow output LED and red stability LED give immediate diagnostic feedback without a programmer.
Comparison with XUKT1KSML2
The sibling XUKT1KSML2 is polarized retroreflective, requiring a reflector and offering 1.5 m range. Diffuse versus retroreflective is a fundamental difference: if the existing install uses a reflector, XUK5APANM12 will not work unless the target reliably returns enough light.
For BOM-locked designs, the XUK5APANM12 carries UL, CSA, and CE approvals, so panel certification is straightforward.
