Contrinex KT#-4155-407 photoelectric contrast sensor

The KT#-4155-407 sensor is suitable for all industrial applications where accurate detection of markings is required. This applies in particular to the packaging and printing industries. The sensor has a teach-in function and five switching tolerance levels. During the teach-in process, intensity levels of background and marking are captured and a detection threshold is set between them. Five tolerance levels allow the user to set a detection threshold either close or very close to the intensity of the marking, or in the middle, or close or very close to the background intensity. Simple teaching takes place either directly on the sensor, or via IO-Link, or via external teach-in. LED indicators facilitate the teach-in process.

Three LEDs automatically emit red, green or blue light, reliably ensuring differentiation even between close levels of contrast. The light spot is very small, measuring just 1.5 x 3.5 mm, allowing even the smallest markings to be detected.

The sensing range is 12 mm, with a response time of 50 µs, and a frequency of up to 10 kHz.

The sensor is available either with a connector (KTS-4155-407) or cable (KTK-4155-407) and operates simultaneously as a PNP or NPN sensor. The connector is adjustable through 0°, 45° and 90°. The space-saving dimensions (40 x 50 x 15 mm) and rugged cubic housing of this small sensor make it suitable for integration anywhere.
