SRI VAARI ENGINEERING & AGENCIES is the most prominent manufacturer and exporter of Photoelectric Sensors . Our Photoelectric Sensors are widely used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. Types : Diffuse Scan : 18 mm - 250 mm Sensing 30 mm - 1500 mm Sensing Thru Beam : 18 mm - 3 mts & 10 mts Retro Reflective : 18 mm â 3 mts 30 mm â 5 mts âUâ Fork : 5mm, 10mm, 50mm Used For : To detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver Remote sensing contain only the optical components of a sensor Allows the sensor, itself, to be very small, the controls for the sensor are more accessible, since they may be bigger Restricted or the environment too hostile even for remote sensors, fiber optics may be used Specifications : Contains the optics, along with the electronics Performs its own modulation, demodulation, amplification, and output switching No electrical circuitry and no moving parts, and can safely pipe light into and out of hostile environments Consists of a receiver located within the line-of-sight of the transmitter Retro reflective arrangement places the transmitter and receiver at the same location Sensing Types : 18mm Type = 500 mm Sensing 30 mm Type = 1500 mm Sensing 18mm Type = 3000 mm Sensing 5 mm 10 mm 50 mm 3 mts 10 mts Applications : Industrial Manufacturing
