Banner Engineering S18 Series Photoelectric Sensors

Banner Engineering S18 Series Photoelectric Sensors feature EZ-beam technology with specially designed optics and electronics for reliable sensing without adjustments. The sensors are self-contained, fixed-field, infrared diffuse mode sensors with far-limit cutoff, a type of background suppression. High excess gain and fixed-field technology allow the components to detect low-reflectivity objects while ignoring background surfaces. The S18 EZ-beam series sensors feature a -40°C to 70°C operating temperature range, <1 microamp at 30V_DCoff-stage leakage current, and 20mA receiver current. These Epoxy encapsulated barrel-mount sensors are leakproof, rated NEMA 6P and IEC IP67 per IEC 60529.

Features

Output configuration (DC voltage):
- SPDT solid-state DC switch; choose NPN (current sinking) or PNP (current sourcing) models
- Light operate- N.O. output conducts when sensor sees its own (or the emitter’s) modulated light
- Dark operate- N.C. output conducts when the sensor sees dark; the N.C. (normally closed) output may be wired as a normally open marginal signal alarm output, depending upon wiring to power supply (U.S. patent 5087838)
Output rating (DC voltage):
- 150mA maximum (each) in standard wiring (when wired for alarm output, the total load may not exceed 150mA)
- <1 microamp at 30V_DC OFF-state leakage current:
- <1V at 10mA DC; <1.5V at 150mA DC ON-state saturation voltage
Protected against false pulse on power-up and continuous overload or short circuit of outputs
Output response time (DC voltage):
- 3ms ON and 1.5ms OFF opposed mode models
- 3ms ON and OFF retroreflective, fixed-field, and diffuse mode models
- NOTE: 100ms delay on power-up; outputs do not conduct during this time

Repeatability:
- 375μs opposed mode models
- 750μs retroreflective, fixed-field, and diffuse mode models
- Repeatability and response are independent of signal strength
Environmental rating:
- Leakproof design rated NEMA 6P and IEC IP67 per IEC 60529
- IP69K per DIN40050 for the quick disconnect and cable models when the cables are protected from direct spray
Vibration and mechanical shock:
- All models meet MIL-STD-202F, method 201A (vibration: 10Hz to 60Hz maximum, 0.06inch (1.52mm) double amplitude, 10G acceleration) requirements
- Method 213B conditions H&I
- 75G with device operating; 100G for non-operation shock
