Capacitive switch offers noncontact
actuation
The 1297/1897 series capacitive switch from CTL Components features programmable sensitivity levels that enable it to be actuated by a light touch or even by the mere proximity of an object.
The 1297/1897 series capacitive switch from CTL Components features programmable sensitivity levels that enable it to be actuated by a light touch or even by the mere proximity of an object Manufactured in Germany by Mentor, the new switch has no moving parts and thus eliminates the problems of wear and tear associated with conventional mechanical switches

Multiturn encoder has multiple bus interfaces
CTL Components has a multiturn encoder with an interchangeable bus interface design, which allows a single encoder body to be combined with a wide variety of different field bus systems.
SMD light pipes with integrated LEDs
New from CTL Components is the world's first range of taped-and-reeled SMD light pipes featuring integrated LEDs.
The proximity capability of the switch opens up an array of possibilities for the designer as it can be located behind a plastic, glass or ceramic panel and protected from hazards such as moisture, dirt and vandalism.
This makes it especially suitable for use in hygiene-sensitive applications, industrial control panels and a wide variety of equipment accessible to the general public, including vending machines, lift control panels, exhibition displays and information terminals.
The switch works by creating a localised capacitive field, which changes when an object comes near, thereby causing a disturbance of the resonant circuit.
If the disturbance exceeds predefined limits, then a switching signal is generated.
Available in both surface-mount and through-hole versions, the capacitive switch can be specified with or without an integral two-colour LED light pipe, which displays the status of the switch in red or green.
This compact device has maximum overall dimensions of just 10 x 10.4 x 28.5mm, a voltage rating of 5 to 30V DC and an operating temperature range of -40 to +85C.
