The Pilz PSEN OP4H-A-30-030/1 is a high-performance safety light curtain designed to provide compact yet effective safeguarding in industrial environments. As part of the well-established Pilz PSENopt family, this model offers a combination of robust protection, compact coverage, and reliable performance, ensuring that operators and machinery remain safe in automation setups where smaller access points or work areas need precise safeguarding.
Operating at a 24 V DC supply, the light curtain is fully compatible with modern control systems and straightforward to integrate into existing safety architectures. Its 950 nm infrared wavelength technology provides highly accurate and interference-free detection, ensuring stable operation even in environments with ambient lighting or reflective surfaces that might disrupt less advanced systems.
The dual OSSD (Output Signal Switching Device) outputs provide an essential layer of safety redundancy. With two independent outputs, the device maintains its protective functionality even in the event of a single-channel fault, ensuring compliance with international safety standards such as EN ISO 13849 and IEC 61496. This fail-safe design makes it suitable for mission-critical applications where uncompromising reliability is required.
The PSEN OP4H-A-30-030/1 has a protective field height of 300 mm, making it ideal for hand protection, small access points, or point-of-operation safeguarding. Its compact protective field is well-suited for workstations, packaging machines, or light-duty robotics where precise safety coverage is needed without extending protection unnecessarily.
Built for industrial durability, this light curtain operates in an ambient temperature range of 0 °C to +50 °C, ensuring consistent performance under typical factory conditions. Its solid design and reliable beam alignment enable long service life, even in continuous production environments. Installation flexibility allows the curtain to be mounted vertically for access guarding or horizontally for detection across work surfaces, adapting to diverse safety requirements.
Typical applications for this model include assembly stations, pick-and-place systems, laboratory automation, packaging machinery, and compact robotic cells. By offering quick response times, it ensures machinery is stopped immediately upon beam interruption, maintaining operator protection without compromising productivity.
In summary, the Pilz PSEN OP4H-A-30-030/1 safety light curtain is a compact, reliable, and efficient safeguarding solution. With its 24 V DC supply, infrared detection, dual OSSD redundancy, and 300 mm protective height, it provides precise safety coverage for smaller applications. This balance of protection, performance, and flexibility makes it a valuable addition to any modern automation environment where operator safety is paramount.
