รายละเอียด||โฟโต้สวิตช์แบบทรงสี่เหลี่ยม รุ่น S18
- Self-contained Class 1 modulated visible laser diode emitters permit higher gain and extended range in opposed mode sensing systems
- Narrow effective beam for small-object detection or for precise position control
- 10 to 30V dc operation; third wire extinguishes laser light when connected to +V dc
- Compatible with all EZ-BEAM® receivers; may also be used with a variety of other Banner modulated photoelectric receivers (see Excess Gain chart below)
- Popular 18 millimeter threaded barrel design

Models S18
Excess Gain S18
Excess Gain of the S186ELD emitter is dependent on the receiver used. Following is a comparison of the excess gain for recommended receivers at 15 m (50'). For information on compatibility of the S186ELD emitter with other Banner photoelectric receivers, contact the factory Applications Group at the address or numbers listed on the back cover.
Alignment
Conventional modulated infrared LED photoelectric emitters are designed with beam divergence angles of several degrees. As a result, most emitters are easily aligned to their receivers by simple line-of-sight methods.
The beam size listed in Figure 1 is also the effective beam size at the receiver. The effective beam is equal to the minimum opaque object profile required to block the light beam. The beam size at the emitter is 2.5 mm (0.1") diameter.
The effect of angular misalignment is dramatic (see Figure 2). The wide beam angles offered by conventional photoelectric emitters allow several degrees of misalignment between the optical axes of the emitter and receiver. This is not true for laser emitters which require their beam center to directly strike the receiver lens. Figure 2 shows how far the laser beam will miss the center of the receiver lens for each degree of angular misalignment. Note that even at only a 5' range, one degree of misalignment will cause the laser beam to miss the lens of most receivers.
Alignment Tip: The visible red beam of the laser emitter is easily seen in subdued lighting. At opposed distances of up to 10', attach a sheet of white paper directly in front of the receiver lens. Mark the location of the lens center on the paper; use the mark as an aiming target. Sight along the beam from directly behind the laser emitter. Adjust the emitter mounting until the red image (the dot of red light) is centered exactly on the mark. Remove the paper and check the response of the receiver.
For longer distances (up to 25'), replace the white paper with a 4" x 4" square of high-grade retroreflective tape (Banner model BRT-THG-4X4-5 or equivalent; see Figure 3). For greater distances, use a larger sheet of retroreflective material (see page 4).
