ABB Smart Sensor for Low Voltage Motors
ABB has developed the Ability Smart Sensor for low voltage motors, which can be rapidly retrofitted to many types of existing low voltage motors. The sensor attaches to the motor frame without wires and uses Bluetooth Low Energy to communicate operational data to a smartphone app, desktop PC, or, in encrypted form, to the cloud for advanced analytics.
The sensor collects data about many variables, including various types of vibration, bearing health, cooling efficiency, airgap eccentricity, rotor winding health, skin temperature, energy consumption, loading, operating hours, number of starts and RPM speed.

ASG Linear Variable Differential Transformers
Alliance Sensors Group (ASG) has launched the LAS-19-A series of spring-loaded AC-LVDTs (linear variable differential transformers). These linear sensing devices are hermetically sealed, contactless devices with an axial connector designed for industrial and commercial applications such as factory automation, metal and paper mills, robotic assembly systems and operation in wet environments.
In addition, LAS-19-A series AC-LVDTs operate from a nominal 3 Vrms, 2.5 to 3.3kHz excitation source. They are packaged in a 19.0mm OD SS housing with an axial 6-pin PTO2A-10-6P connector.

Balluff Ceramic Caps for Sensors
Balluff has released ceramic caps that are designed to extend sensor life by providing a layer of protection to the face of sensors operating in harsh conditions. The caps, which can be added before or after installation, protect flush mount sensors from high temperatures, weld spatter, abrasives and impact.
The ceramic caps also provide end protection for flush-mount and cylindrical-style inductive proximity sensors. They can be threaded in place to protect the most vulnerable area of a cylindrical bodied sensor—where the face meets the barrel—and are compatible with any brand of sensor.

Kyntronics Electro-Hydraulic Actuator
Kyntronics has unveiled its Electro-Hydraulic Actuator (EHA), which combines hydraulics and electromechanical servo technology into a scalable, modular assembly. The EHA is a variable-speed motor, drive and cylinder actuation system that controls position, force and speed in applications requiring from 2,225N to over 445kN of force capacity. The system produces strokes up to 3,048mm.
A core feature of the EHAs is the way in which differential volume is accounted for between a cylinder’s cap and rod ends. To compensate for this differential, the hydraulic cylinder includes an outer low-pressure cylinder with a second inner high-pressure cylinder, creating a chamber between the two.

OMRON MultiAxis Controller
OMRON has introduced its CK3M-series Programmable MultiAxis Controller, which provides nanoscale motion control for manufacturing in the digital and automotive industries.The CK3M-series creates connectivity to virtually any type of motor and encoder using EtherCAT and encoder communication protocols.
This means that only one controller is needed for high-speed synchronous control. Moreover, ANSI C allows machine builders to create their own control algorithms.The CK3M also delivers output speeds of 50 µs/5 axes.
