Interlocked guard:
pick the interlock architecture
Name whether the guard needs a mechanical tongue, non-contact coded sensing, or a lock that holds the door shut, then collect RFQ fields that keep those architectures on separate commercial lines.

An interlocked guard is a movable guard whose position (and sometimes lock state) is monitored so the control system can react when the guard opens. Search results for "interlocked guard" and "machine guard interlock" often dump tongue switches, RFID sensors and solenoid locks into one basket. That mix produces non-comparable offers. This page is a continue/hold architecture fork for the guard itself. It does not publish hazard-zone design rules, invent SIL proofs for a machine, or claim stock, price or certificates beyond the linked family pages.
Architecture fork for an interlocked guard
Write the guard type and the interlock architecture on the same revision. A hinged fence with a tongue head is not interchangeable with a sliding cover that uses coded non-contact sensing, and neither is interchangeable with a locked guard that must stay shut until a stop completes.
| Architecture | What the buyer is buying | Hold if the RFQ only says… | NEWMAZZ family pages |
|---|---|---|---|
| Mechanical tongue / multi-contact | Actuator key enters a head; contact map follows guard position. Actuator often ordered separately. Fits many hinged doors when a physical key path is acceptable. | "Interlocked guard" with no contact map, head material or actuator note. | MA1. Optional handle kit: MAZ-K2 (for MA1/MA2/MA3). [1] |
| Non-contact coded sensing | RFID or magnetically coded open/closed sensing without a tongue slot; coding, distance and output type matter. | "Non-contact interlock" with no coding, operate/disconnect distance or output type. | MAS01–MAS03, MAS11. Magnetic proximity (different duty): MA-GLS. [1] |
| Guard locking on the same guard | Door stays locked until the lock releases; holding force, lock principle and unlock path sit beside the contacts or coded outputs. | "Interlock" when the process needs a locked guard but the RFQ has no holding-force or unlock line. | MA2, MA3, MA50, MA6. Detail fork: guard locking. [1] |
| Captive-key sequence (specialist) | A key that stays trapped until a defined sequence frees access; often isolation or multi-point access, not a simple door sensor. | "Key interlock" with no sequence or isolation vs access duty. | Not listed as a NEWMAZZ family here. Keep the specialist OEM on the worksheet. See trapped key interlock. |
Use this page when the buyer question is "what kind of interlock does this guard need?" Use the safety door switch type map when the question is already framed as a door-switch family comparison. Use guard locking when the only open question is lock vs sensing-only.
Six continue/hold checks
Describe the guard, not only the part name
Input: Hinged door, sliding fence, light cover, or other; how people access the hazard; whether the process needs the guard locked while a hazard can remain.
Decision: Continue when the RFQ states guard type and access scenario. Hold "interlocked guard" with no guard description.
Evidence to request: One-line guard duty the supplier must echo. Catalog entry: machine safety.
Lock the architecture row before price
Input: Tongue, non-contact coded, guard locking, or captive-key specialist (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 shortlist that prices MA1 tongue units against MAS11 sensors as if they were the same item.
Evidence to request: Catalog title that names the architecture.
Specify how the control system learns guard state
Input: Contact map (NO/NC count) or OSSD/output type, and whether dual-channel monitoring is expected upstream.
Decision: Continue when the supplier maps ordering options to your wording. Hold "safety contacts" without a map, or an OSSD quote labeled as dry contacts.
Evidence to request: Contact/output table. Module-side RFQ: MA9Z and the safety relay hub.
If the guard must stay locked, pin force and unlock
Input: Holding force (or N/A), lock principle and voltage if used, unlock method for maintenance.
Decision: Continue when those fields are filled or marked N/A. Hold a lock quote that omits holding force and unlock. Series catalog example: MA2/MA3 list 1,300 N. Confirm the model. [1]
Evidence to request: Lock rating line and unlock page reference.
If non-contact, pin coding, distance and environment
Input: Standard vs unique coding, operate/disconnect distances you will accept, cable or connector preference, IP and temperature band.
Decision: Continue when each offer states coding and distance from its own datasheet. Hold "high coding" without catalog wording. MAS11 family pages publish operate min. about 8 mm and disconnect max. about 17 mm as catalog claims; confirm the model. [1]
Evidence to request: Coding and distance rows.
Ask for documents per architecture
Input: Selection-manual page range, model datasheet, 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.

Short FAQ
Is "machine guard interlock" a different article?
No. Keep that related search on this URL so the architecture checklist does not split across doorway pages.
How is this different from the safety door switch guide?
That guide is a door-switch type map for buyers already shopping switches. This guide starts from the guard duty (tongue vs non-contact vs lock vs captive-key) and the RFQ fields that follow.
Will you publish a generic interlock wiring diagram?
No. Wiring belongs to the selected model's operating instructions. A generic diagram would invent steps this site cannot verify.
