Water-Resistant Ethernet Connectors

Natasha Townsend — Mon, 14 May 2012 13:24:06 +0000

American CONEC Corp. is introducing its water-resistant Ethernet I/O port connectors with a special flange-mount for deployment in harsh environments such as security and surveillance equipment, GPS systems, communications, industrial machinery, and test and measurement equipment.

The die-cast nickel-plated IP67-rated water-resistant connectors enable designers to use popular data ports in harsh-environments. The connectors come in Cat5e or Cat6e configurations for increased protection from contamination and moisture, as well as for mechanical stability, temperature resistance, vibration immunity, and EMI/RFI shielding.

The flange-mounted IP67-rated RJ45 connector with gold-plated contacts can be front or rear-mounted to a maximum panel thickness of 3.20 millimeters, and operates in temperatures from -40 to 85 degrees Celsius. The connectors have a 1/6th turn bayonet coupling, and are operable with gloved hands.

The RJ45 connectors seal out dust and weather with a silicone ring seal that creates a watertight connection to the panel.

COLE HERSEE’S HBW60 SEALED POWER DISTRIBUTION MODULE

Natasha Townsend — Mon, 14 May 2012 12:49:21 +0000

The new HWB60 sealed power distribution module (PDM), a compact PDM ideal for use in space-constrained vehicle battery compartments has a 60-slot HWB60. It accepts plug-in circuit protection components with a 280-style footprint, including Delphi MetriPack 280 connectors, terminals, cable seals, and cavity plugs. Standing up to road splash and salt spray, it provides robust protection to devices. With any combination of mini-fuses, relays, circuit breakers, and diodes, it handles the huge increase in added equipment used in today’s heavy-duty vehicles.

The compact sealed unit measures 113 x 52 x 82 millimeters (4.6 x 2.0 x3.2 in.) making it a perfect fit for accessory circuits, overflow circuits from the main PDM, or as a main module on smaller vehicles. The units are sealed to IP67 standards and can be installed virtually anywhere on the vehicle.

The elimination of internal bussing allows the user to customize circuitry with direct wire-to-component connections. In addition, the terminal position assurance (TPA) locks provide secondary locking protection for the wire leads, preventing them from being pulled out. TPAs snap onto the back after the wires are installed to ensure IP protection.

Being modular, the units can be dovetailed together to expand circuit protection capacity. They can also be interlocked to other Littelfuse PDMs and fuse holders, including FLEC, MEGA Flex holder, and MIDI Flex holder, to provide complete system protection.

Two–Phase Input Power Supplies

Natasha Townsend — Fri, 11 May 2012 15:22:16 +0000

A new line of 2-phase input, DIN rail mounted power supplies from Automation Systems Interconnect Inc. (ASI) has added to its already broad line of power supplies. The new CSW series have been designed to operate using only 2 legs of a 3-phase circuit. The CSW series has a universal input of 185-550 Vac in both single and 2-phase. This solution provides the same output power as a 3-phase input power supply, but at a lower cost and taking less space on the DIN rail. High efficiency and low heat dissipation, as well as, full electronic protection are important performance features.

The CSW series 24 Vdc power supplies are available in 5 and 10 amps, 12-15 Vdc adjustable versions and 7-8 amp and 15-16 amp, and a 48 Vdc model in 5 amp, all with a universal input range of 185-550 Vac.

One of the key features of this new family of 2-phase power supplies is the user selectable output protection. The user can easily select hiccup or constant power protection based on the application. Also, all power supplies have both output overload and short circuit protection and are housed in fully enclosed, touch-safe enclosures.

Turck 24 V-Switching Power Supplies

Natasha Townsend — Fri, 04 May 2012 17:47:44 +0000

A new family of power supplies expands the existing family of power supplies. Designed to efficiently convert ac to dc, these 24 V dc power supplies provide safety extra-low voltage (SELV),, according to EN 60950, and are suitable for the 24 V supply of according equipment and interface modules of the Turck series IM, IMS and IMC.

Offering wide-range input—between 90 and 260 V ac—the 24 V dc power supply can be used in diverse supply networks worldwide. Using an onboard potentiometer, the output voltage can be adjusted from 22.5 up to 28.5 V dc, and styles are available with an output current strength of 2.5, 5, 10 or 20 amps.

Featuring Class 1, Division 2 certification and rated IP20, the power supply was developed specifically to guarantee a dependable dc supply in the industrial environment. This highly efficient power supply can be run in parallel for applications requiring redundancy and includes overload protection of up to 150 percent.

For enhanced operator control and device status, a power relay is a reliable functional check, eliminating potential wire breakage or system malfunction. The device can also bypass power failures automatically, which allows the ac input to disappear for up to 30 ms without any effect on the output.

Sitop PSU100D Power Supply Eliminates Rail Mounting

Natasha Townsend — Wed, 02 May 2012 13:53:44 +0000

The wall-mounted, single-phase, Sitop PSU100D switched-mode power supply is screwed-mounted, which eliminates the need for traditional rail mounting while affordably meeting the basic power supply requirements.

Ideally suited for apparatuses and machines, it features a rugged, low profile, aluminum casing with IP20 degree of protection that requires little space, while enhancing mounting flexibility.

A wide temperature range from -10 to 70 degrees C. accommodates a broad range of applications in harsh environmental conditions. Six fan-free variants provide a regulated supply of 24 V with rated output currents ranging from 2.1 to 6.25 A and 12 V with 3 or 8.33 A. For higher outputs, two devices of the same type can be connected in parallel.

Single-phase connection to almost any public or industrial supply system is possible due to a wide-range input of 85 to 264 V ac, radio interference class B and certification in accordance with CE and cULus (Underwriters Laboratories certification for Canada and the U.S.).

The output voltage can be set between 22 V and 28 V using potentiometers in the 24 V variants, and between 11 and 14 V in the 12 V variant. A green LED indicates the operating status “Output voltage OK.” Electronic short-circuit, overload and overvoltage protection features ensure safety in the event of a fault.
