HB-A1Ms

The HB-A1Ms is an explosion-proof sub-lock, also called a slave lock. It adds a secure, alarmed locking point to a container, tanker or vehicle and pairs over Bluetooth with a master GPS e-lock. The master unit collects the sub-lock status and sends it to your tracking platform, so you can secure several doors while keeping the cost and connectivity in one place.

No. The HB-A1Ms is designed to work with a master lock rather than as a standalone tracker, so it does not carry its own SIM. This is what keeps it compact and low cost. It reports through the paired master lock, which handles the positioning and data upload for the whole group.

Yes. The HB-A1Ms has an IP67 rating, so it is fully dust protected and resistant to rain and washdowns, and it uses an ATEX-certified explosion-proof shell suitable for hazardous or flammable cargo. It operates from -30 °C to +70 °C, making it fit for demanding outdoor and industrial conditions.

The HB-A1Ms supports keyless access through an RFID card (2.5 cm range) or the Bluetooth app (up to 20 m). There are no physical keys to manage, and access can be limited to authorised staff, which strengthens container and cargo security.

It suits any situation that needs more than one secure locking point, including multi-door containers, tanker and trailer compartments, logistics vehicles and safe boxes. Deployed as a tanker security lock, container security lock or safe box lock alongside a master unit, the HB-A1Ms extends coverage and adds an intelligent alarm to every sealed point.
