Why Choose the Carlo Gavazzi PB18CNT15NC Through-Beam Photoelectric Receiver?
The Carlo Gavazzi PB18CNT15NC is a compact and reliable through-beam photoelectric receiver designed for safety-edge sensing and object detection in industrial automatic doors, gates and automation systems. As part of the Carlo Gavazzi PB18 photoelectric sensor series, it combines long-range optical detection with an NPN normally closed switching output for straightforward integration into industrial control circuits.
The PB18CNT15NC operates as the receiver in a separate emitter-receiver photoelectric system, providing a rated operating range of up to 15 m. It is designed for use with 890 nm modulated infrared light and features dark switching, allowing the output to respond when the optical beam between the emitter and receiver is interrupted.
With a 10–30 V DC supply, NPN normally closed output, 5 m cable and IP67 protection, the PB18CNT15NC is well suited to demanding industrial installations. Its ESPE Type 2 classification and support for automatic door and gate standards make it particularly suitable for safety-edge sensing applications.

Reliable Through-Beam Detection for Automatic Doors and Industrial Automation
Through-beam photoelectric sensing uses separate emitter and receiver devices positioned opposite each other. The emitter directs a modulated infrared beam towards the PB18CNT15NC receiver, allowing the system to identify an object or obstruction when that beam is interrupted. This arrangement provides dependable detection over significantly longer distances than many single-housing photoelectric sensing methods.
The PB18CNT15NC combines 15 m range, an NPN NC output and dark-switching operation with a rugged IP67 construction. These characteristics make it particularly effective for automatic door and gate safety-edge sensing as well as industrial machinery where reliable non-contact detection is required.
Typical Applications
- Industrial automatic door safety-edge sensing.
- Automatic gates and access-control systems.
- Machine guarding and presence detection.
- Conveyor and material handling systems.
- Industrial object and obstruction detection.
- Packaging and production machinery.
