Panasonic Through Beam Photoelectric Sensor Fork Style 6 mm NPN IP64 PM-U25-C3

The Panasonic PM-U25-C3 is an ultra-compact through beam photoelectric sensor specifically engineered with a fork-style housing to deliver precise object sensing in automation and control environments. Its integrated U-shaped plastic body contains both the emitter and receiver within a 6 mm slot, enabling fast and reliable detection of opaque targets passing through the gap. This configuration is ideal for applications where space is limited or alignment simplicity is paramount, such as parts counting, edge guiding, small part detection, and presence/absence checks in machinery.

Equipped with an NPN output, the sensor supports easy connection to a wide variety of PLCs and control inputs common in industrial systems. The output is protected against short-circuits and polarity reversals, which helps ensure system uptime and operational safety. The cable termination allows flexible installation options in both fixed and mobile setups within factory automation lines, pick-and-place units, and conveying systems.

The device features a robust polycarbonate and polybutylene terephthalate enclosure that guards the internal electronics from mechanical impacts and vibrations typically encountered in industrial settings. The housing is IP64 rated, ensuring resistance to dust ingress and protection from splash water, making it suitable for most indoor automation tasks. The operating temperature range from -25°C to 55°C allows use in environments with moderate temperature fluctuations.

The PM-U25-C3 operates using an infrared light source, which reduces susceptibility to interference from ambient light, fluorescent luminaires, or sunlight in open plant environments. The detection range of 6 mm, together with a fork style, helps ensure consistent operation even with variable target positioning, while the large, highly visible indicator LED provides clear operational feedback from both sides and above for quick status verification.

Additional protective design features include built-in reverse supply polarity protection, output polarity protection, and output short circuit protection. The sensor mounts easily with standard M2 or M3 screws and is compatible with a wide variety of installations requiring quick replacement or adjustment, maximizing productivity and minimizing downtime.

The PM-U25-C3 adheres to IEC standards and is designed without hazardous area certification, focusing on general industrial and automation use. Typical scenarios include assembly automation, printing machines, packaging lines, and precise detection in conveyor systems. Its use extends across electronics manufacturing, food and beverage industries, and automated inspection where non-contact, rapid sensing is required.
