The FlexFrame 5hp face-mounted speed reducer can be used with International Electrotechnical Commission (IEC) or National Electrical Manufacturers Association (NEMA) motors. This allows users to quickly switch or replace motors; interchange IEC and NEMA motors for export applications; add face, flange, or foot mounts; and use GS convertible shaft adaptors to match any motor to any gearbox. Consisting of a face-mounted speed reducer with a hollow shaft input, the design functions as a gearhead. Built on the Nu-Lobe gear design, they are available in standard 3:1, 4:1, and 5:1 ratios.

With aluminum housings, FlexFrame units are up to 50% lighter with a small profile, creating a good weight-to-torque ratio (power density). They can be used in cantilevered and over-center designs where heavier gearheads are not feasible.

Lightweight surface-mount capacitors

The space-qualified ESCC QPL 3009 series X7R multi-layer ceramic surface-mount capacitors add 200V PME MLCCs in 0805–2220 case sizes. Compact, lightweight, and available with capacitance values of 330pF to 330nF, the capacitors deliver performance improvements compared to 200V MIL-PRF stacked ceramic capacitors and 100V MIL-PRF surface mount products in 100V circuits when space derating rules are applied. This provides effective, high-reliability solutions for space and military applications, including: space launchers, satellite communications, and the input/output filtering lines of space power supplies.

Tested to the European Space Components Coordination’s (ESCC’s) 3009 standard, the ESCC QPL 3009 PME series delivers high reliability performance in voltage ratings from 25V to 200V, capacitance values of 4.7pF to 2.2µF; and 0805–2220 cases with ESA Variant 03, 06, and 07 terminations.

Robot controller power supply

The 240W output ZWS240RC-24 AC-DC power supply is an addition to the ZWS series of 10W to 300W industrial power supplies. Certification to over voltage category (OVC) III enables direct connection to the incoming AC distribution panel, saving cost and space of an isolation transformer. Target applications include robot and machine controllers requiring more protection from incoming input voltage line transients.

The ZWS240RC-24 accepts an 85VAC to 265VAC input and can operate convection cooled in ambient temperatures up to 70°C, derating linearly above 50°C by 3.5% per 1°C. The 24V output voltage is adjustable from 21.6V to 26.4V to accommodate non-standard voltages. Product dimensions are 84mm x 42mm x 180mm.

Typical hold-up times are 31ms, protecting against extended input voltage dips.

The model is also compliant to EN 55011, EN 55032 Class B conducted and Class A radiated emissions, EN 61000-3-2 harmonics, and IEC 61000-4 immunity standards.

Spring engaged, power-off brake

The 1" electromagnetic spring engaged, power-off (SEB) brake for aerospace/ defense is suitable for small actuators and the limited space and difficult performance requirements of missiles and unmanned aerial vehicles (UAVs). The SEBs can withstand extreme temperatures as well as high levels of vibration and shocks.

Motorized positioning stages

The AQ110 high precision series of low-cost, low-profile, motorized single-axis positioning stages includes four cross roller linear stages with travel lengths of 15mm (0.590"), 30mm (1.181"), 50mm (1.968"), and 75mm (2.952"). Open loop repeatability of all stages is 0.5µm using a 10 micro-steps-per-step step motor driver or 0.25µm using a 20 micro-steps-per-step step motor driver. Precision ground lead screws with 2µm of backlash and high precision cross roller linear travel guides assure repeatability of 5µm, and positional accuracy of 10µm.

Each table has a pattern of 16 threaded mounting holes for the addition of custom tooling, and the base has drilled and countersunk holes for easy integration into new and existing applications.

High speed camera

The Phantom v2640 features a 4-megapixel (Mpx) CMOS image sensor (2,048 x 1,952) that delivers image quality up to 26Gpx/second – while reaching 6,600 frames per second (fps) at full 2,048 x 1,952 resolution and 11,750fps at 1,920 x 1,080.

The v2640 features high dynamic range (64dB) and a low noise floor making it suitable to capture clean, high-resolution images at ultra-high speeds. Its high dynamic range shows significant detail while the low noise is beneficial when analyzing the dark regions of an image.

Multiple operating modes offer increased flexibility. Standard mode uses correlated double sampling for the clearest image, while high-speed (HS) mode provides 34% higher throughput to achieve 6,600fps. Monochrome cameras can incorporate binning, which converts the v2640 into a 1Mpx camera that can reach 25,030fps at full resolution, with high sensitivity.

Flight test memory cartridge docking station

To reduce flight test data download times, the RMSR-2006 Rack-Mounted Fibre Channel Data Playback Unit simultaneously supports up to six 256GB TTC media storage cartridges (MSC). This represents a 3x improvement in MSC capacity and a 4x increase in download speed.

The RMSR-2006 also supports hot swap. TTC Media Manager enables the user to access, copy, delete, and declassify data on the installed media cartridges. The user can individually address and control any of the media cartridges within the unit.

Flight test system solutions and MSC data cartridges are used in numerous U.S. Air Force aircraft, including the F-35, F-22, and B2.

Servo drive system

The Sinamics S210 converter for Simotics S-1FK2 motors provides a servo drive system from 50W to 750W. Integrated safety functions in the converters enable rapid engineering via motion technology objects in Simatic S7-1500 controllers. They are connected to higher-level controllers via Profinet and are easily programmed by automatic motor parameterization and one-button tuning.

Integrated safety functions include safe torque off (STO) and safe stop 1 (SS1). In conjunction with the rapid sampling and smart control algorithms of the Sinamics S210, a high-grade encoder system on the Simotics 1FK2 motor, combined with low rotor inertia and high overload capability, permit dynamic performance and precision.

Simotics 1FK2 motors connect to the converters using a 9mm one cable connection (OCC), which includes the power conductors, encoder signal, and brake.
