Seal your connections with Gopher Electronics and Switchcraft

Seal your connections with Gopher Electronics and SwitchcraftThe EN series of harsh environment sealed connectors from Switchcraft® utilize a patented o-ring-free sealing process to ensure their IP-68 rating. The EN3® connector is the larger of the two sizes in the connector series and is approximately 0.75″ in diameter. It boasts one of the largest varieties of standard configurations in the industry. This connector houses between 2 and 18 contacts available in solder, crimp or PC tail configurations. In addition there are cable end, cable to cable, and panel variations to meet all application types. Furthermore, the panel connector is available in the standard straight version as well as two different right angle panel connector options. For the cable and cable to cable connectors there are two different rear boots that complete the assembly and allow a cable diameter up to 0.380″

The EN2 connector series is the newest sealed connector from the Switchcraft® family of products. It offers great versatility in a compact 0.5″ diameter package size. A newly designed contact allows the installer to either crimp or solder the contact. The design also allows for 2 to 7 contacts in the smaller package size. In addition to the standard coupling ring on the cable end connector there is also a winged coupling nut which makes it easier to ensure secure engagement for the smaller connector. This product also uses the patented o-ring free sealing design which rates this product up to IP-68 NEMA 250 (6P).

Honeywell’s 6-D Motion Variant 6DF IMU Sensors

Honeywell’s 6-D Motion Variant 6DF IMU SensorsThe Honeywell 6-D Motion Variant 6DF (six degrees of freedom) Inertial Measurement Unit (IMU) sensors are designed to provide motion, position, and navigational sensing from a durable single device over six degrees of freedom. This is achieved by using MEMS (microelectromechanical system) technology to sense translational movement in three perpendicular axes (surge, heave, sway) and rotational movement about three perpendicular axes (roll, pitch, yaw). Because the movement/rotation along the three axes are independent of each other, such motion is said to have “six degrees of freedom.”

The 6DF Series IMU measures the motion of the equipment onto which it is attached and delivers the data to the equipment’s control module using industry-standard CAN SAEJ1939 communications protocol, allowing the operator to focus on other equipment functions, enabling more precise control than can be achieved by using only the human eye, thus increasing safety, stability and productivity. The 6DF Series is available in two versions: one with a 2 g accelerometer and the other with a 6 g accelerometer.

Honeywell S&C has long been a leader in providing innovative position sensing solutions, such as SMART, Resolvers, and Magnetic devices. With the launch of the new 6DF Series IMU, 6-D Motion Variant, the portfolio is expanding to include a high-end position sensor with sensitive multi-axis motion control. The design of the new product leverages technology that has been successfully used by Honeywell Aerospace in applications for navigation and control, such as missiles and small rockets. The collaboration allows S&C the ability to offer customers an innovative solution for their multi-axis position sensing needs.

ebm-papst Fans, Blowers and Technology

“Giant” is more than a big word at ebm-papst. Its new W3GZ50 series EC axial fan boasts a 1250mm (49.2 inch) blade diameter and is currently the world’s largest-diameter EC air mover with integrated electronics!
ebm-papst Fans, Blowers and Technology

Energy efficient, simple to use, and able to be installed in a variety of air-moving applications, the new series is easily customized by end users – perfect for use with refrigeration condensers, chiller applications, or large-scale ventilation applications. One large W3GZ50 equates to fewer smaller fans being used.
A complete fan assembly like the W3GZ50 series streamlines your purchasing and inventory requirements. The complete fan assembly consists of a motor, blade, venturi and finger guard, all of which have been designed to work together for maximum efficiency and to eliminate the need to work with multiple vendors and patch together a fan assembly from various manufacturers. A complete assembly can simplify your production line by reducing wiring and installation time.

This air mover has an impressive list of features to match its size; namely:

-Air performance- the direct drive motor and blade combination are able to produce over 38,000 CFM and can operate efficiently with backpressure levels of up to 0.8 inches of water.

-Factory balanced blade – the rotating motor and blades are balanced as a complete assembly on the production floor to insure a smooth operation.

-It accepts traditional control inputs – So that you can fully speed control this fan in your application, our integrated electronics will accept a variety of control inputs. For a simple setup, this means you can use either a 0-10VDC input, 0-100% PWM input, or a 4-20mA input from an outside controller to completely vary the speed of the fan.

-RS485 Modbus RTU protocol ready – Many of the previously mute devices that are part of our daily lives are starting to become vocal, whether we like it or not! Our cars, heating systems and even our home refrigerators now are capable of telling us what condition they are in with texts and e mails. The lineup of EC Giants over 500 Watts are ready to be heard as well! If you would like this fan to be a vocal participant in your assembly, it is simple to establish two-way communication using the on-board RS485 Modbus RTU protocol. Not only can you command the speed at which the RPM will run, you can also obtain the run hours, the specific alarm status, internal motor temperature and many other bits of information that will keep you informed and up to date for critical applications. ebm’s ongoing partnerships with key worldwide controls manufacturers make incorporating digital communication easier than ever before.

-Built in PID controller – for ultimate flexibility, the built-in process controller allows you to program this unit to run independently without the need for a separate process controller to handle common field tasks. For example, when programmed to operate in closed-loop sensor mode with your supplied temperature, pressure or other sensor, the fan will maintain a process specific set point. Simply set the sensor parameters and how quickly you want the fan to respond and the process controller will take it from there. The set point can either be entered using software to prevent unauthorized changes or from an accessible potentiometer for simple adjustments by anyone in the field. This powerful feature is a perfect way to reduce components in your overall assembly. Even if you choose not to use this feature as the main process controller, it can easily be programmed and can remain dormant in the background as a backup to the main process controller.

These are just some of the advanced features this exciting new product has to help simplify your larger air moving projects.
