Panasonic CX-421 Photoelectric Sensor
The Panasonic CX-421 Photoelectric Sensor (CX421, UCX421) offers a sensing range of 300 mm, suitable for various applications. It can detect opaque, translucent, or transparent objects, though it's advisable to verify detection with an actual sensor before use. With a repeatability of 1 mm or less and hysteresis of 15% or less, it ensures accurate and reliable operation.
Operating on a supply voltage of 12 to 24 V DC, the sensor has low current consumption of 13 mA or less. The Panasonic CX-421 Photoelectric Sensor features an NPN open-collector transistor output with short-circuit protection, offering flexibility with switchable Light-ON or Dark-ON operation. The response time is swift, at 1 ms or less.
This sensor is ideal for high-precision tasks in industries requiring reliable object detection, offering protection against shock and vibration, and can extend up to 100 m with an appropriate cable.
Our engineers meticulously inputted all the necessary details of this sensor following the datasheet guidelines. However, it’s crucial to acknowledge the potential for errors during this process. Despite our diligent efforts, it’s imperative to remain vigilant as inaccuracies may persist despite our sincere endeavour's.
