Product Overview

MHK 4G GSM Gate Opener is a mobile phone access controller for operating gates, garage doors, barriers, bollards, shutters, access doors, and compatible machines. It uses GSM, 3G WCDMA, and 4G/LTE network communication, allowing authorized users to trigger the relay by phone call or SMS where network coverage is available. For Abu Dhabi homes, villas, warehouses, and commercial entrances, this controller reduces the need for multiple remote controls. The system supports caller ID authorization, ignores unknown numbers, and can manage up to 200 or 1200 authorized users, depending on version. If you prefer the original manufacturer’s model, compare it with the WAYHANG WH-120 PRO 4G opener, which lists similar 4G bands and relay specifications.

Be the first to review “MHK 4G GSM Gate Opener Controller”

Which mobile networks and bands does the MHK 4G GSM gate opener support?

The MHK 4G supports GSM, 3G WCDMA, and 4G/LTE networks, listing EU and AU LTE band sets plus WCDMA B1, B2, B4, B5, and B8. That helps if one network is weak at your gate, but check your operator’s coverage first. The Euromatic 4G lists the EU bands only, so compare both with POWERgate Abu Dhabi.

What is included with the MHK 4G GSM opener, and what power supply must I add?

The MHK 4G pack includes the device, an antenna, wiring terminals, and a quick guide, but no power adapter or push button. It needs AC 9–30V or DC 9–36V, which you can take from a board’s accessory output such as on the FAAC 740D, or buy an adapter, so ask POWERgate Abu Dhabi.

The MHK 4G has a wired switch input — can I still open the gate if the mobile network fails?

The MHK 4G supports a wired switch input as well as calls and SMS, so add a push button for local opening, which is not included. A wired switch also gives you a way in if mobile coverage drops. Its relay is rated 3A at 240V AC, so use it only as a start contact.

At AED 180, how many users does the MHK 4G manage, and how should it be protected in Abu Dhabi?

At AED 180, the MHK 4G manages up to 200 or 1200 authorised numbers depending on version, ignores unknown callers, and works from -10°C to +60°C, so fit it in a shaded box in Abu Dhabi. Add safety photocells such as the CAME DELTA-DIR range for unattended phone opening, and confirm the version with POWERgate Abu Dhabi.
