T-slot magnetic cylinder switches for hazardous dust areas

January 2007 Operator Interfaces, Switches & Relays

The new magnetic cylinder switches MK500A and MK501A from IFM Electronic are specially designed for use in hazardous areas. They meet the requirements of the directive 94/9/EC (ATEX) and can be used in hazardous dust areas of the category 3D (zone 22, non-conductive dusts).

With their innovative mounting feature, the sensors are easily inserted from above into the T-slot where they click home. For easy positioning of the correct switchpoint, the switches can be moved in the slot. They are permanently secured by simply using a slotted screw or hexagon socket screw.

The electronic cylinder switches work without wear and have a much longer life than Reed switches. The high switching frequency of 10 000 Hz makes the switches ideal for fast applications.

Using the IFM mounting adapters, the T-slot cylinder switches can also be mounted on other cylinder types, such as clean-line, tie-rod, integrated profile and trapezoidal slot cylinders.

The sensors are equipped either with a M12 connector or a connection cable, and with their IP 67 protection rating, they are suitable for a wide range of applications. The switches are vibration and shock resistant and are suitable for operating in a temperature range from -20 to 60°C.

IFM Electronic is represented locally by Shorrock Automation.
