Line of manifold mount cartidge valves
Available from the Parker Fluid Control Division, manufacturers of the Skinner and Gold Ring lines of solenoid valves and the Sinclair Collins line of process control valves, is a new line of manifold mount cartridge valves. These cartridge valves are an innovative and simplified alternative to solenoid operators and stud mount valves. The cartridge valve is part of a family of direct-acting solenoid valves for air and liquid (including light oil) applications. These small, yet powerful valves, meet today’s medical, commercial, industrial, mobile, and instrumentation market needs. Economy models are available for less demanding applications.

Offered in two- and three-way models with a stainless steel body, these manifold mount cartridge valves offer a space-saving approach, without manifold orifices to machine or press. Fully assembled, the valves offer no loose parts to assemble, as the sleeve, plunger, spring, and orifice are one unit.

Motorized Screwrail Linear Actuator
The SRA04 Motorized ScrewRail Linear Actuator eliminates the need for external rail-to-screw alignment, simplifying the design, manufacture, and assembly of motion systems. The unit is extremely compact and can save as much as 80% of the space required by a traditional two-rail system.

The ScrewRail consists of a Kerk precision rolled lead screw supported by sealed ball bearings and contained within a concentric steel guide rail, driving an integrated nut and bushing. KerKote TFE coating and self-lubricating nut/bushing material ensure long life and zero maintenance. The ScrewRail is available with either a free-wheeling (SRA) or anti-backlash (SRZ) nut assembly. When mounted vertically, the ScrewRail can be used to simultaneously lift and rotate (Z-theta motion), making the unit ideal for pick-and-place mechanisms.

The motor used on the unit is the Haydon size 11 hybrid double stack stepper motor. The stepper motor is available with either flying leads or an integral connector. The connector is RoHS compliant, featuring a positive latch in order to insure high connection integrity. The connector is rated up to 3A with the mating connector handling a range of wire sizes from 22 gauge to 28 gauge.

No-Drift Absolute Gaging Package
Coupling the Acanto Absolute Length Gage with the ND 2100G Gage-Chek metrology readout delivers a gaging package that is a solution for many fixed gaging applications. The Heidenhain Acanto Absolute Length Gage with EnDat 2.2 provides the benefits of an optical encoder while solving many of the problems of multiple length gages. No longer will quality managers have to worry about their gages drifting, linearity over the entire measuring range, or referencing upon startup. The Acanto’s measuring principle is the measurement standard and does not drift over time, nor does it require mastering. Sweet spots are non-existent with the Acanto as 2µm of accuracy hold throughout the entire measuring length. The new absolute technology, using EnDat 2.2, enables the Acanto to know its position upon power up with no need to reference. The Acanto comes in both spring-operated and pneumatically-operated models, available in 12mm and 30mm measuring lengths.

The Heidenhain ND 2100G Gage-Chek will handle gaging and inspection tasks with ease, from simple pass/fail detection up to complex logic statements communicating to a PLC. Configurable for basic or advanced operations, assigning and combing inputs as desired, along with mathematical, trigonometric, or statistical formulas, are all possible. This makes it possible to measure even complex dimensions such as thickness, flatness, volume, and more. Rapid acquisition of measurement data can monitor dynamic events such as the eccentricity of a rotating shaft.

The Heidenhain ND 2100G Gage-Chek is equipped with a new color LED lit display, which will display results numerically or graphically as a bar graph or dial indicator. The ND 2100G Gage-Chek can manage up to 100 parts, each with up to 16 visible measurement features and 16 hidden ones, while saving thousands of data entry points for internal statistical process control (SPC) or export. User customization is easy with programmable soft and hot keys. Minimum/maximum functions monitor and store data, allowing warning and tolerance limits to be set to each display value.
