Pepperl+Fuchs 418100

The print mark contrast sensor, designated as DKE21-9,5/110/124, is constructed with a durable stainless steel housing. It operates within a detection range of 9.5 mm, with a tolerance of ± 3 mm, utilizing a modulated LED light source that emits visible green, red, and blue light. The sensor projects a rectangular light spot measuring 1 mm by 4 mm, and allows for dynamic Teach-in functionality.

With an electrical operating voltage range of 10 to 30 V DC, this device ensures reliable performance with a no-load supply current of ≤ 60 mA. The push-pull output is designed to be short-circuit and reverse polarity protected, supporting switching currents up to 200 mA and a frequency of 16.5 kHz, with a response time of 30 µs.

For enhanced durability, the sensor conforms to several international standards, including EN 60947-5-2:2007 and IEC 60947-5-2:2007, with significant resistance against shock and vibration. Its degree of protection is rated at IP67, ensuring reliable operation in challenging conditions. The sensor operates effectively in ambient temperatures ranging from -20 °C to 60 °C and can be stored at temperatures between -20 °C and 75 °C.

The sensor features a 5-pin M12 x 1 connector for easy integration and weighs 530 g. Its compact dimensions measure 85.6 mm in height, 33 mm in width, and 60.8 mm in depth, making it suitable for various industrial applications.
