Panasonic EX-31B-PN Photoelectric Sensor
The Panasonic EX-31B-PN Photoelectric Sensor (EX31BPN, UEX31BPN) offers precise detection with a sensing range of 500 mm. It complies with CE marking directives and RoHS standards for quality assurance. With a compact design and IP67 protection, it ensures reliable performance in industrial environments.Operating on a supply voltage of 12 to 24 V DC with minimal current consumption of 10 mA or less for both the emitter and receiver, the Panasonic EX-31B-PN Photoelectric Sensor offers efficient performance. Utilizing a PNP open-collector transistor for output with maximum source current support of 50 mA, it ensures reliable operation with dark-ON output operation and integrated short-circuit protection for added safety.
Engineered to withstand demanding environments, the EX-31B-PN features an IP67 protection rating and sturdy construction comprising die-cast zinc (nickel plated) enclosure, polycarbonate lens, and enclosure cover. With a 2-meter (6.562 ft) 3-core cabtyre cable included, extendable up to 50 meters (164.042 ft) for both emitter and receiver, it offers versatility in installation.
The sensor is lightweight yet durable. Originating from Japan, it upholds the highest standards of quality and reliability associated with Panasonic products. Additionally, two nuts are provided as accessories, enhancing convenience during installation.
