Balluff have expanded its portfolio of magnetic cylinder sensors for pneumatic cylinders by introducing the BMF255, an ATEX ( Zone 0/20 category 1G/1D ) version enabling the sensor to be used in areas with continuous, long term and frequent occurrences of dust, gases and vapours.
On the widely used ‘T’ Slot cylinders the sensor can be inserted from above using the stainless steel secure hold clamping screw, the clamp being situated at the cable end of the sensor helping to prevent any snagging of the cable lifting the sensor out of the slot. For round and tie bar profile cylinders, select the required mounting clamp from the range, plus pneumatic cylinders with tie bars up to 20mm diameter can be accommodated.
The switching function is Namur normally open, there is an LED function indicator and the switch has a protection standard of IP67. The overall length is only 25mm making it well suited for short stroke cylinders. The six metre long integral cable enables the user a quick and easy connection.
Balluff can also supply the isolating amplifier for connection outside of the ATEX zone.
