HIKVISION DS-TMG420 Barrier gates with straight boom pole
The Hikvision DS-TMG420 is a barrier gate with a straight boom pole for entrance and exit management at parking lots, communities, company gates and toll stations. It runs on 220 VAC with a DC brushless motor, is rated for 5,000,000 cycles and its housing is rated IP54 and IK09. It can be controlled by a parking management system or by handle, remote controller or button.
Integrated machine core: A parallel gear reduces speed and drives the linkage arm, which keeps the movement stable and efficient. The carbon steel gears are quenched to resist wear and impact and extend the product life.
Fast opening, slow closing: DC variable frequency control gives smooth operation with fast opening and slow closing. With a 3 m octagonal pole the boom rises in 1.8 s, with a 4 m pole in 2.5 s and with a 6 m pole in 5 s.

Obstacle rebound and opening priority: The gate supports rebound when it meets an obstacle and gives priority to opening. It also supports IR sensors, vehicle detectors and radars as anti-fall devices.
Fault codes and event log: Fault codes appear on the built-in digital (nixie tube) display, together with a log record and status indication. This helps installers find a problem and fix it quickly.
Works during power cuts: You can turn a hand wheel to open the boom and keep the gate open when the power is cut. With optional components, the gate can also open automatically on power cut, for example to let fire trucks in.
Adjustable closing delay: The boom closes after 10 s by default. The delay is configurable, with a minimum of 2 s and 2 s steps.

Who it's for / Works with
Hikvision states the DS-TMG420 series is used at road toll stations, parking lots, communities and enterprise entrances and exits, controlled by a parking lot management system or by handle, remote controller or button.
Good to know
- DS-TMG420 (this model) has no body indicator; its boom direction is right by default and can be switched.
- Hikvision offers DS-TMG420 with a 3 m, 4 m or 6 m octagonal pole or a 3 m or 4 m anti-collision round pole. Ask us which pole length you need.
- Hikvision lists an octagonal straight boom pole and a remote controller as included accessories.
- Rising the boom on power-off is optional and not supported by default.
- The traffic signal light output needs an external power supply (max. 220 VAC).
