Panasonic PM-K45 Photoelectric Sensor
The Panasonic PM-K45 Photoelectric Sensor, with part number PMK45, adheres to the CE Marking Directives, ensuring compliance with EMC and RoHS standards. It features a fixed sensing range of 6 mm, suitable for precise object detection tasks, with a minimum sensing object size of 0.8 × 1.2 mm. Equipped with an NPN open-collector transistor output, the sensor offers two output options: Light-ON and Dark-ON, providing versatility for different application requirements. It consumes minimal power, with a current consumption of 15 mA or less, operating within a supply voltage range of 5 to 24 V DC.
The Panasonic PM-K45 U-Shaped Photoelectric Sensor demonstrates rapid response times, with a response time of 20 μs or less under light received condition and 80 μs or less under light interrupted condition. Our engineers has entered all the specification details about this sensor according to the datasheet.
It is designed to operate in ambient temperatures ranging from -25 to +55 °C (-13 to +131 °F). The storage temperature range is from -30 to +80 °C (-22 to +176 °F). It can operate with ambient humidity levels of 5 to 85% RH. For storage, it can handle humidity levels of 5 to 95% RH. The sensor has an IP64 protection rating, ensuring durability in industrial environments. The sensor can withstand vibration frequencies from 10 to 2,000 Hz. It handles 1.5 mm (0.059 in) double amplitude. It can endure shock accelerations up to 15,000 m/s² (1,500 G approx.).
Our engineers actively inputted all the required details of this item in accordance with the datasheet. Nevertheless, it’s imperative to recognize that errors may arise during this process. Despite our sincere efforts, it’s important to remain cautious. Nonetheless, inaccuracies can still occur.
