Capacitive proximity switches are designed for non-contact and wear-free detection of electrically conductive as well as non-conductive metal objects. Turck is expanding its portfolio of capacitive sensors, now offering 18 mm and 30 mm capacitive barrel sensors with teachable capabilities. The new offering comes in two variants - teach by wire or teach by button.

TURCK Expanded 18 & 30 mm Teachable Capacitive Sensors Distributors

Expanded Teachable

Capacitive sensors utilize a non-contact sensing technology that detects a wide variety of materials. When equipped with sensitivity adjustments users can tune out certain materials such as glass or plastic, making this type of sensor a common choice for point level applications.

If you are looking for TURCK Teachable Capacitive Sensors, please call us at (800) 894-0412 or email us at we will do our best to help you find the 18mm capacitive switch that you are looking for at the most competitive prices possible. If you are searching for 30mm capacitive sensor technical information (data-sheets) please use the datasheets or product selection guide page links.

The teach by button variant can be taught by a single press of a button, saving valuable installation and configuration time. Both present and absent media can be taught for a higher sensitivity teach. The variant without a push button can be taught either by a teach adapter or teach by wire (pin 5), which allows for a tamper-resistant installation. Each variant is available in either PNP or NPN.

The 18 mm housed version offers a 5 mm sensing range when flush mounted and a 7.5 mm range when not flush mounted. The 30 mm housed version offers a 10 mm sensing range when flush mounted, with a sensing range of 15 mm when not flush mounted. The expanded offering can be switched between NC and NO, and provides optical programming feedback through LEDs.

Saginaw Enclosures

These Enclosures are primarily used in an indoor environment to protect against dust, falling dirt, dropping of non-corrosive liquid, and light splashing of water. Saginaw Control & Engineering's Type 12 Pushbutton Enclosures are designed to house oil-tight push buttons, switches, and pilot lights. Add the letter "I" to the end of the part number to receive the enclosure with 22.5 mm international pushbutton holes.

Datalogic Sensors

The Metal Face Line inductive proximity sensors were made mainly for applications in extreme environments and cannot be solved with standard formats. Thanks to their stainless steel active face and the sturdy housing, they are able to withstand the shocks and the aggressive action of detergents and solvents used in environments subject to frequent high-pressure washing. Version are available with a diameter of 12 or 18 mm with M12
