For Intrinsically Safe Operation in Hazardous Areas

• Intrinsically safe sensors featuring EZ-BEAM

technology; the specially designed optics and electronics

provide reliable sensing without the need for adjustments

• "T" style plastic housing with 30 mm threaded lens

• Completely epoxy-encapsulated to provide superior durability, even in harsh sensing environments rated

to IP69K

• Innovative dual-indicator system takes the guesswork out of sensor performance monitoring

• Advanced diagnostics to warn of marginal sensing conditions or output overload

• 5 to 30V dc; constant current output

WARNING: Not To Be Used for Personnel Protection

Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or death. This

device does NOT include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor

failure or malfunction can cause either an energized or de-energized sensor output condition.

Fixed-Field Mode Overview

T30 Series self-contained fixed-field sensors are small, powerful, infrared diffuse mode sensors with far-limit cutoff (a type of background suppression). Their high excess

gain and fixed-field technology allow detection of objects of low reflectivity, while ignoring background surfaces. The cutoff distance is fixed. Backgrounds and background

objects must always be placed beyond the cutoff distance.

Fixed-Field Sensing – Theory of Operation

The T30FF NAMUR compares the reflections of its emitted light beam (E) from an object back to the sensor’s two differently aimed detectors, R1 and R2. See Figure 1.

Fixed-Field Concept on page 2. If the near detector's (R1) light signal is stronger than the far detector's (R2) light signal (see object A in the Figure below, closer than the

cutoff distance), the sensor responds to the object. If the far detector's (R2) light signal is stronger than the near detector's (R1) light signal (see object B in the Figure

below, beyond the cutoff distance), the sensor ignores the object.

The cutoff distance for model T30FF sensors is fixed at 200, 400 or 600 millimeters (7.9 in, 16.7 in, or 23.6 in). Objects lying beyond the cutoff distance are usually ignored,

even if they are highly reflective. However, under certain conditions, it is possible to falsely detect a background object (see Background Reflectivity and Placement on page

2).
