Specification Table

The distance to the hazard source is determined by the minimum detection body and response time of the selected area sensor. A common optical axis spacing of 20 mm (ø25 mm) is typically used. However, for closer distances to the hazard source, an optical axis spacing of 10 mm (ø15 mm) is recommended. Conversely, for longer distances to the hazard source, a cost-effective option is to use an optical axis spacing of 40 mm (ø45 mm).

When approaching the hazard source closely, use a detection body ø15 mm, with an optical axis spacing of 10 mm. This type ensures exceptionally high safety.	Common standard type: Detection body ø25 mm, with an optical axis spacing of 20 mm. A commonly used configuration.	When the distance to the hazard source is far Detection object ø45 mm, Optical axis spacing 40 mm. Please select this when the installation location is far from the hazard source.

Precautions

■About installation

(1) Bracket Installation

3. Precautions for adjacent installation
When two or more sets of area sensors are installed adjacent to each other, mutual interference is likely to occur between the sensors, as shown in Fig. 3-1, where infrared light from the emitter of product ① may affect the receiver of product ②. This may interfere with the protective function of product ②, putting the operator in danger, so the installation method shown in Figure 3-2 must be followed. That is, in the absence of a light-blocking plate, avoid installing adjacent area sensors on the same side. Otherwise, the light emitted from the emitter can easily fall on another adjacent receiver.

Figure 3-1 Illustration of interference between emitter ① and emitter ②

Figure 3-2 Illustration of installation positions for prevention of mutual interference between area sensors

Notes on adjacent installations

4. Correct installation position in the presence of reflective objects
If the area sensor is surrounded by any objects with smooth reflective surfaces, such as metal plates, floors, ceilings, machined parts, coverings, baffles, and glass panels, the area sensor must be installed at a distance greater than A (m) from the reflective surfaces, and the value of A can be derived from the formula or found in the coordinate diagram Figure 4-2. As shown in Figure 4-1, the cone has an aperture angle α that is formed between the optical axis and the light beam at the edge of the optical cone. Where α = aperture angle of light beam, L = distance between emitter and receiver, and L < the maximum transmitting distance of area sensor.
