pd32cnb12npt – photo brr 120mm npn no/nc cab
Carlo Gavazzi PD32CNB12NPT is a miniature diffuse-reflective photoelectric sensor with background suppression, 120 mm teach-in sensing distance, 10–30 V DC supply, NPN NO + NC outputs and a 2 m cable for precise industrial object detection.
Why Choose the Carlo Gavazzi PD32CNB12NPT Photoelectric Sensor?
The Carlo Gavazzi PD32CNB12NPT is a miniature diffuse-reflective photoelectric sensor with background suppression designed for precise short-range object detection in industrial machinery and automation systems. As part of the Carlo Gavazzi PD32 series, it combines a compact 12 × 20 × 32 mm housing with a teach-in sensing distance of up to 120 mm.
Background suppression allows the PD32CNB12NPT to detect the required object while reducing unwanted switching from surfaces located behind the target. Its NPN transistor output with complementary NO + NC switching provides flexible integration with compatible PLCs, machine controllers and industrial automation equipment.
With a 10–30 V DC supply, fast 1000 Hz operating frequency and electronic teach-in adjustment, the PD32CNB12NPT is well suited to high-speed presence and position monitoring. This version is supplied with a 2 m fixed cable and features an IP67-rated ABS housing for industrial installations.

Precise Teach-In Detection with Background Suppression
Diffuse-reflective photoelectric sensors detect objects using light returned directly from the target, eliminating the need for a separate reflector or receiver. Background suppression helps prevent surfaces beyond the selected detection point from causing unwanted switching, making this sensing principle particularly useful in compact machinery where structures or conveyor surfaces may be located behind the target.
The Carlo Gavazzi PD32 series combines miniature construction with electronic teach-in configuration and fast switching performance. The PD32CNB12NPT offers a 120 mm sensing distance and 1000 Hz operating frequency, making it suitable for precise presence, position and component detection in automated production equipment.
Typical Applications
- Small-component presence detection.
- Packaging and production machinery.
- Industrial conveyor object detection.
- Assembly and material handling equipment.
- Component position monitoring.
- High-speed counting and inspection systems.
- Compact PLC-controlled machinery and factory automation.
