ALPRO EB501 12V DC Mini Solenoid Bolt

The Alpro EB501 12V DC Mini Solenoid Bolt is a highly compact and versatile electric locking solution designed for remote access and exit control. Engineered for concealed mortice installation, this slimline mini bolt is ideal for timber and metal doors, as well as narrow profile joinery, cabinets, and showcases.

It is suitable for both sliding and swing doors with single or double-action operations, and can be mounted either vertically or horizontally in the door or frame. Operating on a fail-unlocked (power-to-lock) configuration, the bolt ensures safe egress by retracting automatically in the event of a power failure.

The EB501 features a robust 12mm diameter stainless steel bolt with a 12mm throw, paired with a continuously rated solenoid. It includes built-in door position monitoring for status feedback, and a selectable auto re-lock timer that can be set to 0, 3, 6, or 9 seconds. For added reliability, the unit is fully protected against transient voltages and reverse polarity, and comes backed by a 3-year manufacturer's guarantee.
