Mounting and connection
Before installation of SB3,5-E2, Verify target depth, PNP input polarity and flag clearance. Inspect the exact terminals, mechanical engagement and clearance against the manufacturer's drawing. If the installation is Ex-rated or safety-related, validate the complete certified circuit and site procedure. Do not copy limits from a visually similar suffix onto SB3,5-E2.
Purpose in the process
The operational role of SB3,5-E2 is to detect a metal flag passing through a narrow slot. Document the expected input condition and the required output or mechanical response. A change in host electronics, wiring, hazardous-area classification or process medium can alter whether SB3,5-E2 remains suitable. Similar-looking designations listed below are inventory references only, not declared substitutes.
Installed assembly
For SB3,5-E2, start with the real installation rather than the appearance of a similar component. Record the mating device, drawing revision, power supply, connection, mounting position and environmental conditions. The complete SB3,5-E2 code is the ordering key. Accessories and certificates may be separate line items, so request confirmation of the entire installed assembly.
Order description
An enquiry for SB3,5-E2 should include the exact printed code, quantity, host or mating accessory, approval need and a label photograph. The technical table identifies confirmed values for SB3,5-E2; any uncertain variant choice is explicitly a verification item. Request the appropriate document for every alternative suffix and retain the approved selection with the maintenance file.
Functional acceptance
To accept SB3,5-E2, observe a known normal state and a known changed state at the connected host. Record the measured values, output indication and controller response. Where adjustment or configuration exists, preserve its settings before removing the former unit. Check the working-range edge and repeat the test after final mechanical fixing of SB3,5-E2.
