| Touch-activated photoelectric switches designed to replace capacitive touch switches and mechanical push buttons; The OPTO-TOUCH's solid-state output is activated for as long as a finger, introduced into the touch area (yoke) of the switch, interrupts the infrared sensing beam; Touch buttons are ergonomically designed to eliminate the hand, wrist, and arm stresses associated with mechanical push buttons; They require absolutely no physical pressure to operate; Field covers are designed to prevent inadvertent activation of OPTO-TOUCHs due to objects (loose clothing, debris, etc.) which might accidentally block their sensing beam" |
| Ergonomic design eliminates hand, wrist and arm stress |
| Field covers (black) included to prevent inadvertent activation from loose clothing, debris, etc |
| Optimized for easy mounting with 30 mm threaded base |
| All models are highly resistant to EMI, RFI, and ambient light interference |
| Environmental considerations for use of the two types differ |
| Easily retrofitted to existing machines |
| Infrared LED sensing beam |
| 12000 lux ambient light |
| 0.05 W minimum wattage |
| 2 m cable connection |
| Prolonged exposure of the opto-touch to direct outdoor sunlight will cause embrittlement of the polysulfone housing, window glass effectively filters longer wavelength ultraviolet and provides excellent protection from sunlight |
| One lights whenever power is applied; the other lights whenever the switch is activated making the normally-open (NO) output conduct |
| Normally open/normally closed operation |
| Complementary NPN (sinking) open-collector transistor |
| 150 mA maximum load, less than 1 V at signal levels; less than 1.5 V at full load on-state saturation voltage, less than 1 uA off-state leakage current |
| All models require less than 25 mA (exclusive of load) |
| Protected against reverse polarity and transient voltages |
| All models protected against false pulse on power-up Models with solid-state outputs have overload and short circuit protection |
| Black polysulfone upper housing, fiber-reinforced valox base, polycarbonate-pet polyester blend field cover |
| Thermoplastic polysulfone. 90 percent at 50 deg C (non-condensing). Complementary NPN |
