pa18csr30pam1 – photo rr pl m18 pnp no+nc,plg
Carlo Gavazzi PA18CSR30PAM1 is an M18 retro-reflective photoelectric sensor with a fixed sensing distance up to 3 m, 10–40 V DC supply, complementary PNP NO + NC outputs, M12 connector and IP67 protection.
Why Choose the Carlo Gavazzi PA18CSR30PAM1 Photoelectric Sensor?
The Carlo Gavazzi PA18CSR30PAM1 is an M18 retro-reflective photoelectric sensor designed for dependable non-contact object detection in industrial automation, conveying and machine control applications. Part of the Carlo Gavazzi PA18 series, it combines an industrial-standard cylindrical PBTP housing with integrated amplification and complementary PNP transistor outputs.
Using a GaAlAs LED producing modulated infrared light at 880 nm, the PA18CSR30PAM1 operates with a suitable reflector positioned opposite the sensor. When an object interrupts the returned light beam, the complementary outputs change state, providing reliable product, package and component detection without mechanical contact.
The sensor provides a fixed rated operating distance of up to 3 m when used with the specified ER4 reflector, operates from 10–40 V DC and provides complementary PNP normally open and normally closed outputs rated up to 200 mA. Its M12 × 1 connector, compact M18 housing and IP67 protection support straightforward installation and servicing in industrial machinery.

Reliable Retro-Reflective Detection for Industrial Automation
Retro-reflective photoelectric sensing uses a single sensor and a separate reflector to establish an optical detection path. The PA18CSR30PAM1 transmits modulated infrared light towards the reflector and monitors the returned beam; when an object interrupts that beam, its complementary PNP outputs change state to provide reliable contact-free detection.
With a rated sensing distance of up to 3 m, a maximum operating frequency of 120 Hz and no sensitivity adjustment required, the PA18CSR30PAM1 provides a straightforward solution for product detection, counting and machine monitoring. The M12 connection also allows the sensor or cable to be replaced independently during installation and maintenance.
Typical Applications
- Conveyor object and package detection.
- Packaging and processing machinery.
- Product counting and presence monitoring.
- Material handling and logistics systems.
- Component detection on assembly equipment.
- Automated production machinery.
- Machine sequence and position monitoring.
- General industrial automation and machine building.
