Product Overview

ANSI Heavy Duty Surface mount electric strike is designed for use with ANSI cylindrical locksets. It can be fitted to wooden door,metal door,PVC door ,etc. It features both “electrically controlled” operation for daily use and “manual operation “ for emergencies. Equipped with one set of NO/NC/COM to provide real-time feedback of door status to the access control system.It features a reinforced durable solenoid designed for continuous operation (tested and certified for 1 million cycles of continuous electrification).The strike keeper is made of stainless steel and the internal moving parts are reinforced with 304 stainless steel (static strength is approximately 900kg), making them sturdier and more durable. The operating mode fail secure or fail safe can be adjusted as needed.

Why Buy This Product

Verified 1000kg (2200Lbs) Holding Strength

Solid alloy and stainless steel construction resists violent kick-in attempts and pry-bar forced entries up to 1000kg (2200Lbs).

Seamless Mortise Latch Integration

Installs directly into the door frame, allowing standard cylindrical and mortise latch sets to remain in place for mechanical egress.

1,000,000 Operational Life Cycles

Custom heat-treated stainless steel keeper and heavy-duty electromagnetic valve ensure decades of trouble-free commercial operation.

Adjustable Latch Cavity Alignment

Enables micro-adjustment of the keeper cavity to eliminate door rattling and compensate for seasonal door sag.

Best for These Applications

Commercial Office Suite Entrances

Securing tenant entrance doors equipped with standard mechanical lever handle locksets.

Interlocking Secure Airlocks & Mantrap Doors

High-security access portals requiring instantaneous release and positive lock status feedback.

Educational & Healthcare Facilities

Classroom, clinic, and administrative doors demanding quiet, reliable electronic release during daily traffic.

Emergency Exit & Panic Bar Portals

Rim exit panic devices and crash bars requiring code-compliant electrified exterior release.

Key Advantages

  • High-Strength Stainless Steel Keeper:Precision cast 304 stainless steel latch keeper resists abrasive wear from latchbolts, preventing mechanical jamming.
  • Low Operating Temperature Circuit:Continuous-duty solenoid incorporates current-limiting stepping to prevent coil overheating and frame thermal expansion.
  • Universal Frame Jamb Preparation:Engineered to fit standard ANSI and European mortise cutouts in hollow metal, aluminum, and solid wood frames.
  • Back-EMF Transient Surge Protection:Integrated suppression diode / MOV prevents inductive voltage spikes from damaging access controller relays.

Frequently Asked Questions

The YS-138SUR-S replaces the fixed strike plate in the door frame. When energized (or de-energized, depending on fail mode), the motorized/solenoid keeper pivots open, allowing the door latchbolt to swing free without turning the door handle.
The YS-138SUR-S is configured as a fail-secure electric strike. Many YLI strike models also feature a field-reversible screw allowing installers to switch between fail-secure (power to unlock) and fail-safe (power to lock) on site.
The YS-138SUR-S requires DC12V(DC 24V customizable) with an operating current draw of 12V/280mA(±10%); 24V/140mA(±10%). A regulated access control power supply with at least 1.5A capacity per door is recommended.
Models equipped with the 'LK' designation feature a mechanical hold-open toggle lever. When switched, the keeper remains free-swinging, allowing unrestricted passage during daytime business hours without drawing electrical power.
