SDC AUTOS136V Single Push 36" Electronic Strike

The SDC AUTOS136V is a wired electronic strike rated for 36" door openings, designed for access control deployments where you need to integrate legacy proximity card readers (125 kHz) alongside modern credential types (DESFire, MIFARE, NFC at 13.56 MHz) on the same infrastructure. Unlike solutions that force you to run separate reader hardware, the AUTOS136V handles multiple card formats through a single strike mechanism — reducing installation complexity and cost when retrofitting mixed-credential environments.

Key Features

• Multi-credential support (DESFire, MIFARE, NFC, 125 kHz Prox): Eliminates the need for separate strikes per credential type. One strike serves all formats, cutting material and labor costs in hybrid deployments.
• 24VDC wired operation: Hardwired power simplifies installation in fixed-frame access points; no PoE dependency means you avoid power-budget concerns on shared network infrastructure.
• OSDP and TCP/IP protocols: OSDP (Open Supervised Device Protocol) is the access control industry standard for reader-to-controller communication; TCP/IP support ensures compatibility with cloud or hybrid cloud access control platforms.
• Manages up to 63 doors and 250,000 user credentials: Scales from small multi-door sites (retail, small office) to mid-sized enterprise deployments without requiring multiple controllers or management systems.
• Single push mechanism: Optimized for push-to-open door applications; suitable for emergency egress where fail-safe or fail-secure behavior must comply with local fire codes.
• 36" frame compatibility: Standard opening dimension; confirm existing frame width before ordering to avoid mismatch issues that require frame modification.

Integration and Deployment Context

The AUTOS136V integrates with any access control panel or door controller that supports OSDP or TCP/IP reader output — including modern unified systems and legacy on-premises panels. Because it accepts multiple credential technologies on a single input, it's particularly useful in environments where you're migrating from legacy 125 kHz systems to modern card-less credentials but can't replace all readers in one project phase.

For integrators deploying across multiple building zones, the 250,000 user credential limit handles most mid-market campus environments; validate cardholder database size against your anticipated growth to avoid license or provisioning bottlenecks.

Things to Confirm Before Specifying

Verify that your existing door frame is truly 36" — non-standard openings (32", 40", oversized commercial frames) require different strike models. Confirm your access control panel supports OSDP or TCP/IP reader mode (vs. older Wiegand-only architectures). Test multi-credential reader compatibility with your chosen reader hardware; not all readers support all card formats simultaneously, despite strike-side support.

For related access control infrastructure, consult access control systems to understand panel and reader ecosystem before finalizing strike selection.

Frequently Asked Questions

Q: Does the AUTOS136V work with Wiegand-only readers?

A: No. The AUTOS136V requires OSDP or TCP/IP reader output. Legacy Wiegand readers cannot communicate with this strike.

Q: What happens if power is lost?

A: The AUTOS136V is a fail-safe device — it defaults to the unlocked state on power loss. Confirm this behavior meets your site's emergency egress and security policies before installation.

Q: Can I retrofit the AUTOS136V into a 40" door frame?

A: No. The AUTOS136V is rated for 36" openings only. Using it in a 40" frame will leave gap exposure and compromise lock engagement.

Q: Does it support NFC smartphone credentials?

A: Yes, if your NFC reader outputs OSDP or TCP/IP and transmits the credential over one of the supported formats (DESFire, MIFARE, or generic NFC at 13.56 MHz). The strike itself is format-agnostic.

Q: Is the 24VDC power supply included?

A: No. You must provision a separate 24VDC power supply rated for the strike's steady-state and inrush current draw.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The AUTOS136V succeeds in environments where you have legacy proximity card infrastructure running in parallel with newer MIFARE or NFC systems — a common retrofit scenario in enterprises. The real win here is that one strike handles multiple credential formats via OSDP, so you're not wiring and provisioning separate hardware per card type. That said, the 36" limitation is a hard constraint; measure twice.

Technical Highlights:

• Multi-credential gatekeeping (DESFire, MIFARE, NFC 13.56 MHz, 125 kHz Prox): Eliminates single-format lock-in. Your access control panel sends credentials to one strike regardless of card type — simplifies wiring and provisioning for campus or multi-phase deployments.
• OSDP protocol support: OSDP is the modern standard for reader-to-panel communication; TCP/IP layering adds cloud integration flexibility that older Wiegand architectures cannot match. This future-proofs your strike investment across panel hardware refreshes.
• Credential capacity (250,000 users across 63 doors): Adequate for most mid-market deployments; validate your cardholder database and growth roadmap before specifying — exceeding capacity requires distributed controller architecture or a different strike family entirely.

Deployment Considerations:

• Frame size is non-negotiable. A 36" strike in a 40" opening creates a security gap. Confirm existing door dimensions before purchasing; frame modification is costlier than ordering the correct model.
• OSDP or TCP/IP reader output is mandatory. If your site is running Wiegand-only readers, the AUTOS136V will not integrate — you'll need a Wiegand-compatible strike or reader replacement.

The AUTOS136V is the right choice for integrators managing multi-credential migrations on a fixed timeline: one strike, multiple credential types, standards-based protocol. Use it in hybrid credential environments (retail chains, corporate campuses, education) where you're phasing out legacy readers but cannot replace them all simultaneously.
