BLASI – Magnetic switch
BLASI – Magnetic switch monostable is a compact reed‑type position sensor used on BLASI automatic doors and barriers to detect when the door is open or closed. The BLASI – Magnetic switch monostable changes its contact state only while a magnet on the moving leaf passes close to it and returns to its original state when the magnet moves away. This “one stable state” behaviour makes it suitable for momentary position signals, such as door‑open or end‑of‑travel detection, in BLASI control and safety circuits. Its sealed construction and low‑voltage contacts allow it to be used in indoor and outdoor applications where reliable, non‑contact feedback is required.
Product Details
BLASI – Magnetic switch monostable integrates into BLASI revolving, swing and sliding‑door systems to monitor door position without physical contact. The switch is mounted on the fixed frame while a matching magnet runs on the moving leaf; when the magnet passes the BLASI – Magnetic switch monostable, the internal reed contact switches, sending a clear ON or OFF signal to the BLASI control unit. Once the magnet moves away, the contact returns to its rest position, which supports simple, repeatable logic for open‑door or closed‑door indications. This non‑contact design reduces wear, dirt‑related failures and vibration effects, improving reliability in high‑traffic entrances such as malls, airports and office lobbies.
Designed for low‑power control circuits, BLASI – Magnetic switch monostable typically offers one or more dry contacts suitable for integration with BLASI safety and interlock functions. Its compact body and standard cable or terminals make it easy to mount on frames, pillars or control enclosures without complex alignment. By using BLASI – Magnetic switch monostable, installers gain a straightforward, low‑maintenance position sensor that supports accurate door‑status feedback and contributes to the safe, predictable operation of BLASI‑based automatic‑door and barrier systems.
