The T8 series ultraminiature self-contained photoelectric sensors from Banner Engineering are only 16,3 mm in diameter (diameter of a 10c coin). Despite their small size, 10 to 30 V d.c., T8 sensors offer long sensing ranges of 2 m, in the opposed mode, and either 50 or 100 mm in the diffuse sensing mode, depending on the model selected. This range is many times greater than that of the typical 8 mm diameter inductive sensor and their tiny size also makes them a low-cost alternative to diffuse (bifurcated) fibre-optic sensors.
As the newest members of the Banner EZ-BEAM family of sensors, T8 series sensors require no adjustments to operate. These visible-beam miniature sensors are designed for precision sensing in small areas previously accessible only to remote sensors and fibre-optic cable. Typical applications include mounting on compact conveyors, packaging machines, circuit board and semiconductor wafer handling equipment, document handling equipment, robot end-efectors, feeder bowls, between the rollers of narrow conveyors, and as replacements for damaged small diameter inductive proximity sensors. They are also a suitable choice for in-die and on-die sensing applications including press performance monitoring, feed detection, feeding fault detection, material positioning, part out verification, slug stacking, die protection, quality validation (error proofing), transfer press finger sensing, positioning and nesting of parts.
T8 sensors also feature versatile outputs. Users can choose either a NPN (sinking) or PNP (sourcing) outputs, capable of switching up to a 50 mA load. They can also choose models for either light operate (NO) or dark operate (NC). A red LED indicates 'light sensed'. These sensors, despite their tiny size, feature a rugged ABS sealed housing that stands up to tough applications.
The housing is leakproof and meets the IP67 standards for harsh environments. Integral protective circuitry guards the sensors against reverse-polarity and transient voltages, short circuits and false pulse on power-up. Users can choose models with an integral 2 or 9 m prewired cable or 150 mm 'pigtail' pico-style, quick disconnect cable.
