AutomationDirect now offers Datalogic print mark contrast sensors with 6-12mm sensing distances. We also now offer the Contrinex DW-series of extended and triple-distance proximity sensors in 3mm to 30mm cylindrical and 20mm rectangular styles.

Contrast Sensors for Print Mark Detection

Datalogic print mark contrast sensors, with 6-12mm sensing distances, are designed to detect the difference in the wavelength of the reflected light between a target mark and background. Contrast sensors use RGB light emission with automatic selection, and feature teach-in sensitivity adjustment, and selectable light on/dark on outputs.

contrast sensors The S8 Series compact contrast sensors feature horizontal spot orientation, a 25 kHz switching frequency, NPN or PNP logic output, 12-30 VDC operating voltage, and are available with IP67-rated plastic or IP69K-rated 316L stainless steel housings. The S8-series sensors, starting at $68.00, are fitted with a 4-pin M8 quick-disconnect or have an attached 150mm cable with M12 quick-disconnect.

New TL Series contrast sensors feature vertical or horizontal spot orientation, 10-30 VDC operating voltages, aluminum housings, and NPN/PNP or PNP logic outputs. TL-series sensors are fitted with a 5-pin M12 quick-disconnect with adjustable exit angle; models are available with 0-5VDC analog outputs and 15, 20, or 50 kHz switching frequencies. These IP67-rated contrast sensors start at $130.00.

Datalogic print mark contrast sensors are CE, RoHs and Reach compliant, and are cULus approved.

Contrinex 3mm to 30mm Tubular and Rectangular Inductive Proximity Sensors

Proximity sensors allow non-contact detection of objects. They are used in many industries, including manufacturing, robotics, semiconductor, etc. Inductive sensors detect metallic objects while capacitive sensors detect all
other materials.

Contrinex DW series inductive proximity sensors are available in barrel sizes from 3mm to 30m, and in a rectangular 20mm x 32mm configuration. Extended and triple sensing distance versions are available for both standard industrial and harsh duty applications. With 10 to 30 VDC operating voltage and sensing distances ranging from 1mm to 40mm, cylindrical sensors are available in shielded and unshielded models with nickel silver, nickel silver/chrome, chrome plated brass, or stainless steel housings. DW-series 3mm sensors are fitted with an axial cable; other sizes offer two-meter axial cable, M8 or M12 quick-disconnects. DW-series proximity sensors have an LED indicator and are available with NPN and PNP, and N.O. or N.C. outputs. Starting at $52.00, DW series industrial proximity sensors have an IP67 rating; harsh duty versions have IP68/IP69K ratings.
