Omron’s oil-resistant, IP67G-rated sensors solve this problem by providing rugged durability for harsh environments. By eliminating oil ingress from any direction, they minimize unexpected downtime and significantly reduce the overall cost of ownership of machinery.

The secret to these sensors’ impenetrability lies in the unique composition of their outer cable sheaths. Composed of fluororesin, a special rubber developed by Omron that provides superior resistance to corrosion, these outer cable sheaths prevent cutting oil from reaching the fiber core. This ensures the machinery’s longevity and cleanability even in the harshest of environments.

What is fluororesin?

Fluororesin is a hydrogenated nitrile butadiene rubber that has been blended with fluororubber in a unique compound that suppresses cable swelling and deterioration. In general, fluorocarbon-based synthetic rubbers have strong resistance to a broad range of chemicals, and Omron’s compound has been specifically optimized to protect against cutting oil.

By preventing cutting oil from penetrating joint surfaces, the fluororesin outer cable sheaths are instrumental in protecting the printed circuit board (PCB) inside the sensor.

Additional protection from Smartclick

In addition to cable sheaths, joints and moving sections, cutting oil can enter through gaps between dissimilar materials. Several of Omron’s oil-resistant sensors use a patented structure known as Smartclick in combination with an O-ring seal to completely prevent gap creation. The single-motion locking seals and blocks all oil ingress.

The combination of Smartclick and O-ring seal also eliminates screw loosening due to vibration, a major challenge of many manufacturing environments.

What does IP67G signify?

Omron’s cutting oil-resistant sensors are given the rating IP67G, which indicates protection against dust and water immersion up to one meter. IP stands for “Ingress Protection,” a set of standards used to define the ability of an electrical device’s sealing to resist intrusion from foreign materials. The G signifies resistance to oil.

Omron’s IP67G-rated sensors pass the IP67G standard oil drop test as well as Omron’s own extended life test and oil-immersion testing. By resisting oil ingress for up to four years, these components solve problems at all phases of production.

Examples of oil-resistant sensing technologies from Omron

Designed to eliminate oil ingress by any path, the following components help manufacturers prevent unplanned downtime.

The IP67G oil-resistant photoelectric sensors, model E3ZR-C, have a fluororesin outer cable sheath as well as laser sealing without adhesives.

The IP67G oil-resistant proximity sensors, models E2ER and E2ERZ, also have a fluororesin outer cable sheath and are heat-welded with a fluoro component. Standard and chip-immune models are available.

The IP67G oil-resistant connectors, model XS5R, employ the Smartclick structure and O-ring seal as well as a fluororesin outer cable sheath. Omron’s technology combines forming and sealing methods with surface bonding techniques to ensure maximum protection.

Benefits of Omron’s IP67G-rated sensor line include increased longevity, enhanced quality control, added flexibility, better efficiency and decreased downtime.
