Balluff Products and Solutions

Balluff hardware at PLC Direct includes magnetostrictive linear position sensors, sensor accessories, and related automation hardware for installed Balluff-equipped systems. The collection is led by the BTL magnetostrictive sensor family, which accounts for the majority of the products.

Balluff Product Families

• BTL Magnetostrictive Linear Position Sensors: The BTL series is Balluff’s magnetostrictive linear position sensor platform for absolute, non-contact position measurement. BTL sensors use the magnetostrictive principle: a magnetic position encoder moves along the sensor rod, and the system measures its precise location using torsional stress-wave timing to deliver an absolute position output with no mechanical wear and no need for reference runs. BTL sensors are available in rod configurations for installation directly inside hydraulic cylinders (measuring ranges from 25 mm to over 7,500 mm), profile-housing configurations for external linear-axis measurement, and extreme-environment variants in full stainless steel construction rated to IP69K and up to 1,000 bar pressure for high-pressure hydraulic applications. Outputs cover analog (4-20 mA, 0-10 V), SSI, IO-Link, CANopen, PROFINET, EtherNet/IP, and EtherCAT interfaces. ATEX- and IECEx-certified variants are available for Zone 0 and Zone 1 hazardous-area installations. Confirmed part number prefixes in the collection include BTL5, BTL6, BTL7, BTLZ, BTLPF, and BTLBTA series, with confirmed variants including BTL5-A11-M0875-P-SA167-S32, BTL6-A110-M0360-A1-S115, BTLZ-5-GS08-1270-A, BTLPF1400-0127-C15AC0A0-000S15, BTLPF1400-0250-C15AE0A0-000S15, and BTLBTA-A21-0450, along with BTLCONTROL and BTLMODULE system components.

• BES Inductive Proximity Sensors: The BES series covers Balluff's inductive proximity sensor range for non-contact detection of metallic objects. BES sensors are available in standard M8, M12, M18, and M30 threaded barrel housings as well as rectangular form factors, with flush and non-flush mounting options, PNP and NPN outputs, and IO-Link communication. They are used across discrete manufacturing for part presence detection, end-of-travel sensing, machine guarding, and high-cycle counting applications where reliable non-contact detection of metal targets is required.

• BOS Photoelectric Sensors: The BOS series covers Balluff's optoelectronic sensor range for object detection using through-beam, retroreflective, and diffuse reflection operating principles. BOS sensors are used where detection of non-metallic objects, longer sensing ranges, or color and contrast differentiation is required. Available with standard PNP/NPN switching outputs and IO-Link, BOS sensors are deployed across packaging, material handling, conveyor, and assembly automation applications.

• BCC Connectivity and Cordsets: The BCC series covers Balluff's connectivity portfolio of pre-assembled M8 and M12 cordsets, cables, and field-wireable connectors for sensor and actuator wiring in automated systems. BCC connectivity accessories are used to wire Balluff and compatible third-party sensors and I/O devices into automation panels and fieldbus systems.

• BMF Magnetic Field Sensors: The BMF series covers magnetic field sensors for detecting the position of pneumatic cylinder pistons through the cylinder wall. BMF sensors mount directly to standard pneumatic cylinders and detect the magnetic field of the piston magnet, providing end-of-stroke detection without any mechanical contact or bore through the cylinder body.

• BNS Cam and Position Switches: The BNS series covers Balluff's cam switches and coded position switch systems for detecting the angular or linear position of machine axes. BNS cam switches use adjustable cam discs to actuate switching elements at programmable positions, and are used for multi-position detection on rotary and linear axes in machine tools and industrial machinery.

• Industrial RFID and Identification Systems: Balluff’s identification product line includes HF (13.56 MHz) and UHF (865-928 MHz) read/write systems for part tracking, tool identification, and production traceability in manufacturing and logistics environments. RFID hardware includes read/write heads, data carriers (tags), and controller interfaces compatible with IO-Link and fieldbus systems.

• IO-Link Infrastructure and Networking: Balluff’s IO-Link and networking portfolio covers IO-Link masters, hubs, and smart IO modules that provide point-to-point digital communication between sensors, actuators, and the control system. IO-Link infrastructure enables parameter configuration, diagnostics, and the exchange of process data with connected field devices over standard unshielded sensor cables, supporting Industry 4.0 data integration at the field level.
