No pressure
The latest innovation from sensor specialist ifm electronic is designed to be easier to use and maintain than a traditional pushbutton. The new KT51 series consists of capacitive sensors built into a standard M22 pushbutton housing, complete with LED indication for actuation feedback
No physical pressure is needed to activate the button, just the presence of even a gloved finger, yet the KT51 won’t react to a film of moisture, in fact it is sealed to IP69K on the front face. Sometimes pushbuttons can be contaminated with dust, crumbs and other residue, which gets into the openings in the housing. The KT51 in contrast is fully sealed.
In addition, the KT51 is available in two versions with either static or dynamic operation. Static operation means the switch is made while the operator’s finger is present, while dynamic operation provides a fleeting pulse as the finger approaches, detecting a change and so ignoring any possible deposits left from the previous activation.
