Magnetic safety switch:
coded non-contact vs tongue
Separate magnetically coded and RFID non-contact sensing from mechanical tongue interlocks, then collect coding, distance and output fields so quotes stay comparable.
Published 3 November 2026 · By JOYLINKTECH · Series facts cite NEWMAZZ MAS and related family pages. Related "magnetic safety switches" searches stay on this URL.
Buyers searching "magnetic safety switch" (and the plural "magnetic safety switches") often mean a magnetically coded non-contact pair that reports guard open/closed. Some RFQs still receive tongue interlocks or solenoid locks in the same shortlist. Those are different products. This page is a continue/hold fork for magnetic / coded non-contact sensing versus mechanical tongue sensing, aligned to the NEWMAZZ MAS families documented on this site. It does not invent sensing distances, stock, price or certificates beyond the linked pages, and it does not treat MAS03 magnetic holding force as a guard-lock rating.
Sensing fork that changes the quotation
Write the sensing principle on the revision before unit price. A magnetically coded pair is not a low-cost tongue substitute when your drawing assumes a key slot, and a tongue head is not a drop-in for a coded non-contact mount.
| Architecture | What the buyer is buying | Hold if the RFQ only says… | NEWMAZZ family pages |
|---|---|---|---|
| Magnetically coded non-contact | Coded magnetic actuator and sensor pair; contact arrangement and cable length vary by model. No tongue slot. | "Magnetic safety switch" with no coding, contact map or operate/disconnect distance. | MAS11 (operate min. about 8 mm; disconnect max. about 17 mm as series catalog claims; confirm the model). [1] |
| RFID / coded non-contact (OSSD-style families) | RFID coded sensing with transistor/OSSD-style outputs on some families; coding and output polarity belong on the same sheet. | "RFID switch" or "magnetic" used interchangeably without naming RFID vs magnetic coding or output type. | MAS01, MAS02, MAS03 (standard/unique coding as catalog claims). [1] |
| Non-contact with magnetic holding (not a lock) | Coded non-contact sensing plus a light magnetic pull that helps seat a light cover. Catalog holding force is far below solenoid lock ratings. | RFQ that treats "magnetic holding" as a guard-lock holding-force line. | MAS03 lists up to about 15 N magnetic holding as a series feature claim. For true locks see guard locking. [1] |
| Magnetic proximity (door open/close detection) | Proximity detection for open/close status; different duty from coded safety pairs. Confirm whether your drawing needs coded safety sensing or proximity only. | "Magnetic switch" with no coded-safety vs proximity duty sentence. | MA-GLS (detection distance 15 mm or more as catalog claim; confirm the model). [1] |
| Mechanical tongue (not magnetic) | Actuator key enters a head; contact map follows guard position. Use when a physical key path is required or already drawn. | Shortlist that prices tongue units against MAS11 as the same commercial line. | MA1. Wider type map: safety door switch. |
If the guard must stay locked until a hazard is clear, leave this sensing fork and open the guard locking checklist. Solenoid lock series on this site include MA2 and MA3 (1,300 N series catalog holding force; confirm the model).
Six continue/hold checks
State coded non-contact vs tongue vs proximity duty
Input: One sentence: magnetically coded pair, RFID coded non-contact, magnetic proximity only, or mechanical tongue.
Decision: Continue when the duty is explicit. Hold "magnetic safety switch" with no sensing principle.
Evidence to request: Duty line echoed on every offer. Browse machine safety.
Pick the MAS / MA-GLS / MA1 row before price
Input: Target family row from the fork, or a named OEM code you are replacing.
Decision: Continue when every quotation uses that row, or when a supplier proposes a different row with a written deviation. Hold a mixed shortlist of tongue and coded non-contact as one line.
Evidence to request: Catalog title that names sensing principle.
Pin coding and operate / disconnect distances
Input: Standard vs unique coding where applicable; operate and disconnect distances you will accept.
Decision: Continue when each offer states coding and distance from its own datasheet. Hold marketing "high coding" without catalog wording. Series catalog example: MAS11 operate min. about 8 mm, disconnect max. about 17 mm. Confirm the model. [1]
Evidence to request: Coding and distance rows.
Specify outputs in the same vocabulary as the datasheet
Input: Normally closed safety contacts (arrangement by model) vs OSSD/NPN/PNP transistor outputs; dual-channel expectations upstream.
Decision: Continue when the supplier maps options to your wording. Hold an OSSD quote labeled as dry contacts, or "safety contacts" without a map. MAS11 describes normally closed safety contacts (arrangement depends on model); MAS01–MAS03 list dual NPN/PNP or OSSD-style transistor outputs as catalog claims. Confirm models. [1]
Evidence to request: Contact/output table. Module-side: MA9Z.
Separate magnetic holding from guard locking
Input: Whether you need only a light magnetic seat force, or a true lock holding force.
Decision: Continue when the RFQ marks magnetic holding as N/A or as the ~15 N-class MAS03 feature (confirm model), and routes true lock needs to the lock fork. Hold any quote that equates MAS03 holding with MA2/MA3 lock force.
Evidence to request: Holding-force line with units, or explicit N/A.
Ask for documents, not a verbal "magnetic approved"
Input: Datasheet, selection-manual page range, dimensional drawing, certificate copies only if your project requires them.
Decision: Continue when each offer points to storeable files. Hold brand adjectives without page numbers. JOYLINKTECH does not invent certificates or stock claims.
Evidence to request: PDF page numbers tied to each code.

Open MAS11 for magnetically coded contacts, MAS01–MAS03 for RFID/coded non-contact families, MA-GLS for magnetic proximity, and MA1 when the drawing still needs a tongue. When the worksheet is filled, prepare an inquiry or email customer@joylinkrobot.com. Suitability and commercial terms need confirmation for the proposed configuration.
Short FAQ
Are "magnetic safety switches" a different article?
No. Keep the plural on this URL so the sensing checklist does not split across doorway pages.
Is a magnetic safety switch the same as a guard lock?
No. Coded magnetic sensing reports open/closed. Guard locking holds the door shut until the lock releases. See the guard locking fork for holding force and unlock fields.
Will you publish a generic magnetic-switch wiring diagram?
No. Wiring belongs to the selected model's operating instructions. A generic diagram would invent steps this site cannot verify.
