500kg (1000Lbs) holding force, fail-secure, 12/24 VDC/AC, 12V/550mA(±10%); 24V/1100mA(±10%), Painted Steel, 90Lx35Wx67H(mm).
The YLI YS-139NO is a commercial-grade electric door strike delivering 500kg (1000Lbs) holding strength. Engineered with precision stainless steel keeper mechanism, fail-secure operational mode, and tested to exceed 1,000,000 continuous door release cycles.
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 âelectrically controlledâ operation for daily use and âmanual operation â for emergencies. It features a reinforced durable solenoid designed for continuous operation and fail safe and fail secure versions are optional..The strike keeper is made of stainless steel and the internal moving parts are reinforced with 304 stainless steel ,making them sturdier and more durable.
Why Buy This Product
Verified 500kg (1000Lbs) Holding Strength
Solid alloy and stainless steel construction resists violent kick-in attempts and pry-bar forced entries up to 500kg (1000Lbs).
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.
