Balluff Introduces the New Standard for T-slot Magnetic Field Sensors

Florence, KY: Balluff has expanded their line of magnetic field sensors with the introduction of the BMF 235, designed to fit a wide variety of T-slots. Cylinder positions can be detected on virtually any aluminum walled pneumatic cylinder with integral T-slots including short stroke cylinders and grippers. The GMR (Giant Magnetoresistive) electronic sensor features an extremely short 23mm housing and an ultra bright LED for easy diagnostics.

The BMF 235 easily drops into the T-slot from above and is secured using a standard screwdriver or an Allen wrench. The sensor installs flush in the slot with nothing protruding for safe secure mounting in space restrictive applications. A cable clip is provided with the sensor for strain relief and ease of cable routing.

This mini-sensor features high accuracy, short over travel, and low hysteresis. The BMF 235 is available in PNP normally open and normally closed versions in a tough IP67 housing, each with cable or pigtail M8 or M12 connectors. Balluff magnetic field sensors include short circuit reverse polarity protection and an industry leading LIFETIME warranty.

For additional installation and product savings, the BMF 235 is available in Balluff's innovative V-Twin® version of two sensors and only one connector (M8 or M12). The V-Twin® versions are especially cost effective when sensing multiple points and providing a means of doubling the number of inputs in MIB.

Balluff also provides an on line Pneumatic Cylinder Sensor Resource Center designed to help you select the best solution for specific cylinder models and will generate up to three recommendations. Visit the online resource center at
