What the complete MJ35-F12-1N-5M code means for this installation
Pepperl+Fuchs MJ35-F12-1N-5M is a NAMUR magnetic-field sensor used to detect a magnetic actuator at a defined gap. This service brief separates the confirmed identity of MJ35-F12-1N-5M from the installation choices that must be checked on site. The shared Pepperl+Fuchs main image is an illustrative category montage, not an exact photograph of MJ35-F12-1N-5M. Use the complete designation on the fitted label when enquiring or replacing the part.

Installation question
At installation, Check both NC channels and the matched NAMUR evaluation circuit. Confirm power is isolated where required and compare the connector or terminals against the current manufacturer documentation for MJ35-F12-1N-5M. Verify safe-area and hazardous-area boundaries where applicable; the exact certificate and site wiring govern the final decision. Leave enough clearance for the fitted cable and normal service access.
What must the unit do?
In operation, MJ35-F12-1N-5M is intended to detect a magnetic actuator at a defined gap. Establish the real input condition, the expected output response and the acceptance limit. Where an accessory, receiver, host card, reflector or magnet is required, include that matched part in the bill of materials. Do not infer that the picture or a neighbouring model code establishes compatibility for MJ35-F12-1N-5M.
What evidence is retained?
Before ordering MJ35-F12-1N-5M, photograph the nameplate and document what is connected on each side of the device. Check supply, signal or mechanical interface, mounting, environmental exposure and the receiving controller. The table is a compact technical reference for MJ35-F12-1N-5M; a similar printed string can denote another function, rating or certification. Retain any parameter backup and the current drawing with the maintenance record.
Commission MJ35-F12-1N-5M with an observable, known condition rather than only checking an indicator lamp. Record at least two input states and their controller responses, then test the edge of the real working range where practical. If MJ35-F12-1N-5M is part of a safety or Ex installation, use the site's approved proof-test procedure and exact approval documents. Save settings, photos and measured results so a later replacement can be compared reliably.
What should purchasing quote?
A useful quotation request for MJ35-F12-1N-5M includes the full code, quantity, site function, connection type, any mating accessory and required approval. Ask the supplier to confirm every changed suffix on a proposed alternative. This page does not declare that other visually similar codes are interchangeable with MJ35-F12-1N-5M; each requires its own data and fit review.
