Electric strike ES-081 NC


The ES-081 NC electric strike by Spreest provides secure locking and instant unlocking – ideal for access control in offices, apartments, and at entrance gates.
The compact, steel electric strike ES-081 NC operates in fail-secure (NC) mode. This means that in the event of a power failure, the door leaf is automatically locked – meeting the "fail-secure" requirements.
The electric strike is symmetrical, making it suitable for both left and right-hand doors, and its EURO 95 mm spacing with additional 52 mm holes and slim design means it fits most door frames, cassettes, aluminum profiles, and door systems.
Key features
- Fail-secure (NC) – No power = door locked; 12 V DC applied = door unlocked
- Memory function – A short pulse (≥ 0.5 s) keeps the strike unlocked until the first opening of the door leaf, even if power is interrupted.
- Manual lock – A switch on the body allows the strike to be left constantly open or closed.
- Symmetrical design – One model for left and right-hand doors.
- EURO / DIN 95 mm – Fits popular cassettes; additional 55 mm holes.
- Strength 6000 N (≈ 600 kg) – Reliable locking even under strong pressure.
- Minimum release force ≤ 30 N – Does not strain the handle or the electric strike in the intercom.
- Latch play adjustment ± 1 mm – Easy adjustment to curved frames.
- Low consumption 0.8–1A – Does not overload the power supply.
- Quiet operation – Included RL207 diode suppresses potential overvoltages and "humming."
- Over 200,000 cycles – Long lifespan with daily use.
- Stainless steel / galvanized – Resistance to corrosion and mechanical damage.
