The COVID-19 pandemic has greatly increased the demand for non-contact push-buttons and switches, since the invisible transmission of viruses and bacteria are often through high-contact surfaces. A wide variety of technologies for contactless switching are vying for the attention of developers and buyers, but not all technologies are the same. There are instances, for example, where false signals are picked up by the sensor under certain conditions (eg, splashed water, rain) and this triggers unintentional switching.
The optical TOF (time-of-flight) technology used in SCHURTER’s TTS contactless switch can be programmed with precision and prevent such errors. Detection distance to activate the switch can be programmed at 60 to 0.05 mm, meaning that wiping over when cleaning the switch surface will not trigger and activate the sensor. The advantage of such customisable detection distance is that the switch can be used as a photoelectric barrier for certain applications.
Housed in stainless steel, visual feedback and status indication are via a bicolour ring illumination (red/green) in the actuator, whose input voltage is between 5 and 28 VDC. Maximum switching voltage is 42 VAC/60 VDC with a maximum current of 100 mA.
