Balluff presents the BMF series of binary-switching,
magnetic-field sensitive, electronic cylinder switches offering precise and
bounce-free switching response, simple handling and universal use.
The latest range of magnetic field sensors for
space-critical applications, the new BMF 243 compact sensor offers high
performance reserves for cylinders with weak as well as strong magnets and delivers
high repeat accuracy and small hysteresis. Measuring only 3.8mm x 24mm, the new
sensors are the ideal choice for particularly small grippers and cylinders with
C-slots.
Since the bracket is already integrated in the
sensor, no additional mounting bracket is necessary; simply inserted into the
slot from above, it can be mounted anywhere the insertion point for the slot is
obstructed by weld splatter or dirt, fitting completely into the cylinder slot
without protruding. The switch point is adjusted in seconds using a
screwdriver. The BMF 243 is supplied with a cable clip that guarantees optimum
strain relief and secure cable routing.
Designers can use the miniature sensors of the
BMF series from Balluff to implement highly dynamic application concepts in
pneumatics that can only be realised with low-weight components having small
space requirements. The BMF 243 compact sensor ideally complements two other
Balluff miniature sensors: the BMF 103 and the BMF 303. The user can therefore,
freely select from two mounting concepts – the integrated bracket or an angle
bracket in C-slots.
BMF sensors query individual positions including
the end positions of pneumatic cylinders, wear-free and precisely, and detect
the permanent magnet mounted on the piston rod through the non-magnetic
cylinder wall. As soon as the piston nears, the output signal switches to the
other state.
