Key Feature Summary:
Heavy-Duty Construction:Built for harsh industrial environments.
High Current Rating:Can switch loads up to 10A directly, often eliminating the need for an interposing relay.
IP67 Rating: Fully sealed against dust and temporary submersion, making it suitable for washdown applications (e.g., food & beverage, pharmaceutical).
Versatile Actuator: The top-push roller plunger (2RQ8) is ideal for applications where the actuating object approaches from directly above the switch.
European Conduit Standard: The PG thread is a metric standard commonly used in Europe and Asia. For North American NPT threads, the equivalent model would be BZE7-2RQ8-NPT .
