About This Product

This is a proximity switch with an intrinsically safe explosion-proof structure. Stable operation over a long detection distance reduces equipment stoppages due to malfunctions and sensor failures due to collisions with the detection target, improving equipment availability.

■Common precautions regarding Zena Barrier

- Only sensors that have passed the combination test can be used. ・Please store in a non-hazardous location and in a container with IP20 or higher rating.

■Notes

・Wiring/operation/maintenance/inspection work should be carried out by someone with specialized knowledge and skills in the construction of explosion-proof electrical equipment and related laws and regulations. - When installing in a hazardous location, the hazardous area where it can be installed varies depending on the model, so be sure to check the corresponding hazardous area. ・Specifications/design etc. are subject to change without notice.
