High Speed Barrier MIB 20

High Speed Barrier 115V, 60 Hz, 240 watts in RAL 9010 White, RAL 2000 Orange, and RAL 1028 Yellow.
Opening or closing time 0.9 second with our standard octagon arm flange.
Drive gate unit is adjusted for arm that is ordered with unit.
Includes: MLC controller with display, built in position sensor provides precise barrier arm status information to controller; up/normal/down switch; receptacle, output relays, and power switch. Built in dual channel loop detector.
Maximum arm length for automatic open on power failure is 10 feet.

Technical Description
The combination of our proven and reliable electric motor with a lever system represents a simple and extremely reliable drive solution. It permits short opening and closing durations without the barrier boom bouncing in the end positions. The lever system locks the barrier boom at both end positions. In the event of a power failure, it can still be moved easily by hand.
The complete drive system is attached to the barrier housing as a single unit, and can easily be removed from the housing by removing the mounting screws.
A built-in spring mechanism provides a precise counterbalance for the barrier boom.
The springs are factory set to correspond with the boom length prior to delivery. If necessary, the springs can be easily reset in situ during assembly, for example if the barrier boom is shortened or if signs are attached to the boom. It is also a simple matter to change the handing on-site from right-axial to left-axial.

The Drive Unit
The two barriers MIB 10 and MIB 20 differ in the type of motor drive they are fitted with. In the end positions, the motor remains with voltage applied but at reduced power. This power is dissipated in the form of heat, which prevents the occurrence of condensation and corrosion. This guarantees consistent opening and closing times, even in cold climatic conditions.

MIB 20
The heart of this barrier is the special AC torque motor. The features of this motor are its long service life, freedom from maintenance, and the fact that it is possible to stall it in any position without risk of damage. Imprecise friction clutches and limit switches are not necessary. The position sensor sends precise data concerning the position of the barrier boom to the control unit. The optimum brake position of the barrier boom is always guaranteed as a result of the control mechanism developed by Magnetic. The control mechanism is equipped with self-learning software which prevents any subsequent bounce of the barrier boom. The barrier is factory wired and ready to connect, tested and supplied with mounting accessories.

Housing
The housing is manufactured from 14 gauge zinc plated sheet steel on to a base frame of stainless steel, then phosphate and powder coat finished for maximum protection against corrosion. Control units are mounted onto a removable zinc plated sheet steel panel. All of the components within the barrier housing are readily accessible through the maintenance door and removable top cover. The housing is supplied in an RAL 2000 orange color finish as standard. Other colors are available on request, at extra cost.

Barrier Boom
The Round Barrier Boom MSB 4
The round boom is made of highly stable aluminum Ø 3“ x 1/18“ profile, and finished with an RAL 9010 white powder coat then applied with bright red reflective tape strips.

The Octagonal Barrier Boom MSB 5
This boom is extruded from highly stable aluminum alloy to produce an octagonal profile of 4“ x 21/8“ x 1/16“ and finished with an RAL 9010 white powder coat then applied with bright red reflective tape strips.

The Control Device
Both the MIB 10 and MIB 20 barriers may only be operated in conjunction with the respective MLC controllers especially developed by Magnetic. Refer to the applicable MF data sheets for relevant details in each case.

Available Versions
Barriers may be supplied with the barrier boom fitted to either the right or left hand side. In its standard configuration the maintenance access door is positioned on the road side, although on request it can be any one of the other sides.
