1000kg (2200Lbs) holding force, fail-secure, DC12V (24V need orderï¼, 12V/320mA(±10%);24V/160mA(±10%), Surface by coating nickel, 230Lx40.5Wx30H(mm).
The YLI YS-621-S is a commercial-grade electric door strike delivering 1000kg (2200Lbs) 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
YS-621-S is suitable for fire exit door with Push-rod lock.The operating principle of electric strike is that electromagnetism produces the force to pull or push the release lever so that to lock or open the door.
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.
