Modular Encoders

CUI's Motion Group (Tualatin, OR) offers AMT21 series absolute modular encoders with multi-turn output capability. Offering 12 bits or 14 bits of absolute position information, the multi-turn units implement a 14-bit signed number turns counter for applications rotating beyond 360 degrees. Users can track position even during power down conditions, while the turns counter can be maintained via a battery backup, eliminating the need for a homing sequence. The encoders are resistant to dirt, dust, and oil typically found in motion applications. A high-speed RS-485 protocol for fast and low-latency position data is accompanied by a current draw of 8 mA at 5 V and a compact package with locking hub for ease of installation. The encoders feature accuracy of ±0.2 mechanical degrees at operating temperatures from -40 to +105 °C in either radial or axial orientations.

Controller System

AutomationDirect (Cumming, GA) released the ReeR MOSAIC modular, expandable, and configurable safety controller system for managing all safety functions of a single machine or an entire plant. As a standalone controller, the M1 master module has eight inputs, two safety outputs, two status outputs, and two inputs for Start/Stop interlock (RST) and external device monitoring (EDM). By adding up to 14 expansion modules, the system can have up to 128 inputs, 16 safety outputs, 16 RST/EDM inputs, 32 status outputs, and Ethernet/IP or MODBUS TCP/IP connectivity. The master module, input expansion modules, and output safety and status expansion modules are DIN rail mount and 24 VDC powered; all modules have removable terminal blocks with screw contacts. EtherNet/IP and Modbus TCP/IP communications modules are available to connect to most industrial fieldbus systems.

Stepper Motors

JVL Industri Elektronik A/S (Birkerød, Denmark) offers MIS171 to MIS176 ServoStep integrated stepper motors with a NEMA 17 42 × 42-mm flange. The motors include a controller with six different industrial Ethernet protocols, absolute multiturn encoder, closed loop, and M12 connectors. All necessary electronics in a stepper system are integrated in the motors, enabling their use in most motion control stepper or servomotor applications. The motors are available as standalone units with programmable motion controller or controlled from an external PLC or PC. Eight I/O points can be individually configured as digital input, digital output, or analog input. Modbus RTU or CANopen provide connection to a PLC or HMI. An ActiveX/OCX driver is available for interface to LabView, Excel, VB, or other Windows programs. Up to 254 axes can be connected on the same RS-485 bus.

Rotary Vane Pump

The Pascal 2021 HW from Pfeiffer Vacuum (Nashua, NH) is a two-stage rotary vane pump suited for applications where water vapor is expected, such as low-temperature sterilization and drying. An optimized gas ballast system allows pumping of large volumes of vapor without condensation inside the pump, preventing accumulation of fluid that would adversely affect the service life of the pump and the pump oil. The pump utilizes special materials to resist aggressive chemicals such as hydrogen peroxide. A safety device impedes the water from entering into functional sections of the pump if the steam capacity is inadvertently exceeded. Accessories include an oil mist filter and inlet traps. An oil drain valve simplifies maintenance in confined spaces.
