YJMKOI 2026 Upgraded ANSI Heavy Duty Electric Door Strike Lock – 12VDC, Fail-Safe / Fail-Secure

Overview

Meet the YJMKOI 2026 Upgraded ANSI Standard Heavy Duty Electric Door Strike Lock, designed to modernize access control without sacrificing reliability. Crafted from a high‑quality alloy, it resists corrosion and rust even with daily use, and it remains steadfast in challenging environments. This upgrade channelizes a robust exterior through a compact interior mechanism, delivering dependable performance in busy entryways.

When electrified, the strike lock offers impressive endurance: it can withstand up to 1000 kg (2200 lbs) of impact and has a tested life of over 500,000 cycles. Operating at 12V DC, it provides a stable power draw suitable for a wide range of door frames and control panels. The combination of durability and efficient power use makes it suitable for both new installations and upgrades to existing locks.

Two operation modes for flexible security

The device offers two adjustable modes to suit different situations. In Fail Safe (NC), the door unlocks when power is off, ideal for interiors and areas where safe egress is critical. In Fail Secure (NO), the door remains locked when power is off, providing additional security for exterior doors. Changing modes is simple: loosen the screw and switch to the other mounting hole. This adaptability helps you align the hardware with your door behavior and safety requirements.

Versatile application and easy integration

This upgrade aligns with ANSI standards and can be used to convert cylinder locks and mechanical locks into electronic access control systems. It supports a wide variety of door types and configurations, making it suitable for offices, shops, schools, and small facilities that need scalable access control solutions. It is designed to help you upgrade without replacing entire lock hardware.

Key benefits include:

• Durable construction with corrosion resistance for long-term performance
• High impact tolerance after electrification for added security in active environments
• Very long cycle life to minimize maintenance and downtime
• Clear mode selection to balance safety and security as needed
