Technical identity, constraints and acceptance of MMB70-12GH50-1N

Pepperl+Fuchs MMB70-12GH50-1N is a magnetic field sensor used to detect a magnetic actuator across a machine gap. This entry identifies the complete MMB70-12GH50-1N designation and shows the technical data that can be used as a starting point. The shared main image is a Pepperl+Fuchs category reference montage, not an exact photograph of MMB70-12GH50-1N. Final selection still requires the fitted label, the latest manufacturer record and the actual site drawing.

Key technical data

Installation record

For a replacement MMB70-12GH50-1N, compare the full printed code character by character. Confirm supply, I/O direction, signal type, terminal or plug pinout, operating environment and mechanical clearances. If the circuit has functional-safety or hazardous-area requirements, obtain the exact approval documents for MMB70-12GH50-1N; the visual similarity of another code is not a valid substitute. Include mating heads, reflectors, boards, cables and licences as separate line items where needed.

Process role

The job of MMB70-12GH50-1N is to detect a magnetic actuator across a machine gap. Define its boundary in the real installation: what connects upstream, what response is required downstream, how it is powered and how it is mounted. A model that looks like MMB70-12GH50-1N may not provide the same circuitry or approvals. Capture the present configuration before removal, including any addresses, calibration, scaling, taught limits or software settings.

Test record

At commissioning, Check magnet position, NAMUR input and sensing distance. Test MMB70-12GH50-1N in the assembled system using a known input or mechanical condition, then read the corresponding output and controller response. Repeat at the low and high ends of the real operating window. A status LED alone cannot prove that MMB70-12GH50-1N has the correct settings, connected accessory or alarm action. Keep the measured values and any deviations in the maintenance record.

Order record

An RFQ for MMB70-12GH50-1N should quote the complete designation, required quantity, installed controller or host, connection style, certification need and the intended operating environment. Request confirmation for any alternate suffix. Related-looking models are indexed below to help identify inventory, but technical table values on this page apply only to the named MMB70-12GH50-1N variant where verified. Each other complete code needs its own specification review.

Related-looking model strings

These designations visually resemble MMB70-12GH50-1N; they can still have different functions, ratings, interfaces and approvals. Verify each complete code independently before ordering or substitution.

Close-out

After the handover of MMB70-12GH50-1N, archive the exact label, configuration backup, drawings and test result. If the process or host changes later, redo the relevant match and acceptance checks for MMB70-12GH50-1N. Do not treat the product montage or the related-code index as a wiring diagram or a declaration of interchangeability.
