The Keyence OP-87420 is a tungsten electrode probe designed for use with the SJ-EH and SJ-EA Series static eliminators. Electrodes form the heart of static elimination systems, generating ions that neutralise electrostatic charges across production environments. As these probes are subject to continuous discharge cycles and environmental conditions, durable and reliable replacements are critical to maintaining stable static elimination performance. The OP-87420 has been engineered precisely for this purpose.

Constructed from tungsten, the OP-87420 delivers exceptional hardness and resistance to wear. Tungsten’s high durability ensures a long service life, even under demanding operational conditions, such as high-frequency discharge or extended run times. This robustness reduces maintenance frequency and helps facilities lower long-term costs while ensuring continuous and effective ionisation.

The probe features a dark-grey finish, making it easily distinguishable from other electrode variants, such as the light-grey OP-87418. This distinct colour coding aids technicians during installation or servicing, ensuring the correct electrode type is used for SJ-EH or SJ-EA models. Quick visual identification streamlines maintenance tasks and helps reduce downtime.

By maintaining stable and balanced ion discharge, the OP-87420 supports the performance of SJ-EH and SJ-EA Series static eliminators. These units are widely deployed in industries where precise electrostatic control is vital, including electronics manufacturing, semiconductor processing, automotive assembly, printing, and packaging. Reliable ionisation prevents issues such as electrostatic discharge (ESD), dust attraction, and product defects—helping to safeguard sensitive components and maintain high-quality output.

The OP-87420 also offers ease of integration and replacement. Sold separately, it allows for straightforward electrode maintenance without requiring full system replacement. Facilities can keep spare probes on hand, enabling proactive maintenance schedules that minimise unexpected downtime and ensure continuous protection against static-related issues.

In practical use, the tungsten construction ensures that the electrode delivers consistent discharge performance over extended periods, even in challenging environments. Its resilience against erosion and operational wear allows the SJ-EH and SJ-EA systems to maintain their efficiency, protecting production processes and optimising workflow reliability.

In summary, the Keyence OP-87420 tungsten electrode probe is a robust, reliable, and purpose-built component designed to support the SJ-EH and SJ-EA Series static eliminators. With its durable tungsten construction, dark-grey finish for quick identification, and ability to provide stable ion discharge, it ensures long-lasting performance and effective static elimination. For industries that depend on precision, consistency, and quality assurance, the OP-87420 is an essential accessory that upholds both system reliability and operational efficiency.
