Panasonic PM-R25-P Photoelectric Sensor
The Panasonic PM-R25-P Photoelectric Sensor is a compact, U-shaped micro photoelectric sensor designed for reliable and accurate object detection in limited spaces. With a fixed sensing range of 6mm, this ultra-small sensor is perfect for fine-positioning and presence detection in high-speed automation environments.
Its repeatability of 0.01mm or less and response time as fast as 20μs enable precise control even during rapid operations. Equipped with PNP open-collector output and both Light-ON/Dark-ON modes, the PM-R25-P adapts easily to diverse system requirements. The unit also integrates short-circuit protection and features an orange LED indicator for clear operational feedback.
The rugged design offers IP64 protection against dust and water, while the infrared LED light source ensures reliable sensing for objects as small as 0.8 x 1.2mm. Certified to meet CE, UKCA, ISO 13849-1, and UL/c-UL standards, the PM-R25-P is built for dependable performance under harsh industrial conditions.
This sensor’s compact body, strong shock resistance, and easy-to-integrate 4-core cabtyre cable make it an excellent choice for demanding detection tasks.
