{"product_id":"e3t-ft21-b0h1t2br5n","title":"Through-Beam Photoelectric Sensor E3T-FT21 - 300 mm Sensing Distance, NPN Output - 1 Count","description":"\u003cp\u003eThis listing is for a single E3T-FT21 through-beam photoelectric sensor offered as a replacement-style unit. Reference sources describe the model as a through-beam sensor with a nominal sensing distance of 300 mm and an NPN output (light-ON). The sensor is an ultrathin, compact design suitable for space-constrained installations. Please confirm physical dimensions, connector type, and electrical compatibility against your equipment or the manufacturer's datasheet before installation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eReplacement for E3T-FT21 form factor - compatible with equipment using the E3T-FT21 style through-beam photoelectric sensor; verify fitment and connector before ordering.\u003c\/li\u003e\n\u003cli\u003eThrough-beam detection with nominal sensing distance of 300 mm (supplier references list 300 mm as the sensing range).\u003c\/li\u003e\n\u003cli\u003eNPN output, light-ON operation reported in reference material - suitable for NPN-input PLCs and control circuits.\u003c\/li\u003e\n\u003cli\u003eCompact ultrathin body - scraped dimensions approximately 7 x 9.5 x 14.6 mm (estimate); check manufacturer datasheet for exact mounting and clearance.\u003c\/li\u003e\n\u003cli\u003ePackage contents: 1 x E3T-FT21 photoelectric sensor.
