Leuze PRK318B/4P Photoelectric Sensor
The Leuze PRK318B/4P Photoelectric Sensor, Part No. 50116858, is a cutting-edge solution for industrial automation. The 318B series sensor operates on the reflection principle and boasts a guaranteed operating range of 0.02 to 4.5 meters, extendable to 6 meters with a reflector TK(S) 100x100. Illuminated by a red LED with a wavelength of 620 nm, this sensor falls under the exempt group according to EN 62471 standards.The Leuze PRK318B/4P Photoelectric Sensor is electrical specifications include a supply voltage of 10 to 30 V DC, open-circuit current ranging from 0 to 15 mA, and a switching element using a PNP transistor for both light and dark switching principles. With a fast response time of 1 ms and a readiness delay of 300 ms, the sensor outputs signals through a 4-wire cable with a length of 2000 mm. Encased in an M18 x 1 mm plastic housing made of ABS, the sensor features an LED display and operates in temperatures ranging from -40 to 60 °C. It carries an IP67 degree of protection, belongs to protection class III, and holds certifications including c UL US, complying with IEC 60947-5-2 standards. Manufactured in China, this sensor finds application in diverse industrial environments.
