Panasonic Compact, U-shaped Photoelectric Sensor PM-K45-C3

Panasonic Sensor PM-K45-C3 Through-beam, 6 mm (fixed) Sensing range, NPN open-collector transistor with two modes: Light-ON and Dark-ON, 5 to 24 V DC

The Panasonic PM-K45-C3 is a compact, U-shaped photoelectric sensor from the PM-45 series, with a built-in amplifier. It is a through-beam sensor, meaning the emitter and receiver are on opposite sides of the 6 mm fork opening. This sensor detects objects that pass between the two sides of the fork, interrupting the infrared light beam.

Specifications

• Sensing method: Through-beam
• Sensing range: 6 mm (fixed)
• Minimum sensing object: 0.8 x 1.2 mm opaque object
• Response time: 20 µs (under light received condition) and 80 µs (under light interrupted condition)
• Output: NPN open-collector transistor with two modes: Light-ON and Dark-ON
• Output indicator: Orange LED that lights up when the light beam is received
• Supply voltage: 5 to 24 V DC
• Current consumption: 15 mA or less
• Cable: 3 m (9.843 ft) cabtyre cable
• Environmental protection: IP64-rated, providing protection against dust ingress and splashing water
• Operating temperature: -25 to +55 °C (-13 to +131 °F)
• Housing material: PBT resin enclosure with a polycarbonate display section

Features

• Space-saving design: The sensor has the same compact mounting pitch as older models, allowing for space savings in industrial setups.
• Robust construction: The unit is designed to resist vibration and shock, with cable and circuit joints encased in resin.
• Built-in amplifier: The integrated amplifier simplifies wiring and eliminates the need for an external amplifier.
• Multiple protection circuits: The PM-K45-C3 includes built-in protection against reverse supply polarity, reverse output polarity, and output short-circuits.
• Easy visibility: A large, multi-angle orange LED indicator makes it easy to check the sensor's status.

Applications

The PM-K45-C3 is commonly used in industrial automation and control systems for various detection tasks:

• Positioning: Detecting the position of objects or mechanical parts.
• Limit sensing: Identifying the start or end position of a moving body, such as on a pallet or conveyor.
• Object detection: Sensing the presence or passage of items on a production line.
• Robotics: For tasks requiring precise object sensing within a small, defined area.
