SICK Background Suppression Photoelectric Sensor Block Sensor Detection Range 25 mm to 400 mm PNP Output IP66 WTB9M4L-3P1191

SICK WTB9M4L-3P1191 Background Suppression Photoelectric Sensor is a robust block-style sensor designed for industrial automation applications requiring precise detection of small or transparent objects. Operating over a detection range of 25 mm to 400 mm, this sensor features PNP output with a cable wire terminal type and a 4-wire interface, using a red light source for accurate detection even through challenging backgrounds.

Constructed with a durable plastic housing and mounted using a hole mount type, the sensor is rated IP66, IP67, and IP69K, ensuring resistance to dust, water, and high-pressure cleaning, making it ideal for harsh industrial environments. It operates reliably within a temperature range of -10°C to 50°C, suitable for varied industrial settings.

Its quick response time of 1 ms supports high-speed applications, while the sensor is capable of detecting materials such as methyl methacrylate and plastics. Certified by CE and UL, the sensor assures quality and compliance with industry standards. Maximum electrical ratings include 30V DC voltage and 100 mA current capacity.

The WTB9M4L-3P1191 sensor belongs to the SICK W9 series, known for rugged VISTAL™ housings that protect against mechanical damage and environmental interferences, employing SIRIC® technology for suppression of optical and electromagnetic disturbances. These features extend machine uptime and reliability.

Applications include detection of the smallest workpieces, inspection through narrow openings, and object detection with background suppression in automation, manufacturing, packaging, and quality control processes. Its highly visible light spot facilitates quick alignment and installation.

The sensor utilizes red light as the light source for reliable detection. It operates within a temperature range of -10°C to 50°C for versatile industrial use. Equipped with a cable wire terminal and a 4-wire interface for flexible connectivity.

Rated IP66, IP67, and IP69K for harsh industrial environment resistance. Designed with a durable plastic housing and hole mounting for secure installation. Response time is rapid at 1 millisecond, enhancing detection speed.

Suitable for detecting materials like methyl methacrylate and plastic. CE and UL certified ensuring compliance with international standards. Maximum DC voltage rating is 30V and current is 100mA. Precise background suppression reduces false detection in complex applications.
