Through-Beam Photoelectric Sensor E3T-FT21 - 300 mm Sensing Distance, NPN Output - 1 Count

This 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.

• Replacement for E3T-FT21 form factor - compatible with equipment using the E3T-FT21 style through-beam photoelectric sensor; verify fitment and connector before ordering.
• Through-beam detection with nominal sensing distance of 300 mm (supplier references list 300 mm as the sensing range).
• NPN output, light-ON operation reported in reference material - suitable for NPN-input PLCs and control circuits.
• Compact ultrathin body - scraped dimensions approximately 7 x 9.5 x 14.6 mm (estimate); check manufacturer datasheet for exact mounting and clearance.
• Package contents: 1 x E3T-FT21 photoelectric sensor. Images show the sensor only; mounting hardware or analyzer body are not included unless listed.
