Arbitrary function generators customise waveforms

Arbitrary function generators generate standard or user-defined waveforms with crystal controlled sampling rates up to 125MHz, 14-bit vertical resolution and up to 4 million horizontal points.

A new series of arbitrary function generators is now available in the UK from Metrix Electronics. They can generate standard or user-defined waveforms with crystal controlled sampling rates up to 125MHz, 14-bit vertical resolution and up to 4 million horizontal points. Uses include signal simulation and test in many industrial, laboratory and service applications.

Customised waveforms can be created from scratch, or by editing standard waveforms.

A PC arbitrary waveform editor programme allows the user to create, edit and download complex waveforms.

Multiple waveforms can be stored in flash memory.

Three models offer standard 31, 40 or 50MHz; sine, square, ramp or pulse waveforms outputs.

A choice of amplitude, frequency and FSK modulations are included, as well as extensive trigger modes.

A fourth model has dual-channel 50MHz outputs that can operate independently or in sum mode to create more complex waveforms.

All models include IEEE488.2 SCPI compatible and RS-232C remote control interfaces.

Adaptor kits are available to rack mount the bench instrument cases.

Connector family gains UL recognition

The Harting RJ Industria connector family has been recognised by Underwriters Laboratories - one of the world's leading compliance authorities.

The Harting RJ Industria connector family has been recognised by UL (Underwriters Laboratories), one of the world's leading compliance authorities. 'UL recognition of this product range is an important step forward in our growth plans in the international marketplace,' said Kevin Canham - marketing manager: 'Although UL recognition has traditionally been mainly requested by customers in the United States, the increasing globalisation of the electronics market means that this recognition is now just as important for users in Europe and Asia.' The Harting RJ Industrial connector family was specifically designed for use in Industrial Ethernet systems. Included in this range is the world's only RJ connector, which can be attached to both solid and stranded Ethernet cables with a cross-section of AWG 22 using IDC technology.

The heart of the connector is the RJ45 data module, which incorporates four HARAX insulation displacement contacts, to reliably connect Category 5e cables (AWG 22-24) or solid cables (AWG 22-23).

For Category 6 Gigalink applications, Harting also has a UL approved product to offer in IP20 to IP67.

It also meets the requirements for fast data networks as specified in IEEE 802.3.

Caged slide nuts avoid cabinet reworking

Caged slide nuts offer that little adjustment to make a panel fit 'just so' - they allow +/-2mm adjustment 360 deg around the hole centre so fittings can be moved to position correctly.

How often do you find you need just a little adjustment to make a panel fit just so, but can't face the re-work? Well, courtesy of the EMKA Program 1056 2D Nut, now you can make that adjustment easily. Simply open up the hinge mounting holes to 10mm dia and fit new M6 caged slide nuts from EMKA - these allow +/-2mm adjustment 360 deg around the hole centre so hinges, catches, handles, cover stays, door stops and slam locks can be moved up, down, or diagonally over a 4mm range to ensure a perfect fit and seal.

Program 1056 2D nuts are a simple push fit in M10 hole and accept standard M6 screws as used on most critical fit cabinet equipment.

In fact the added flexibility provided is useful for any M6 screw mount accessory and is especially useful for large equipment doors where maintenance of close tolerances or sagging in service can cause problems aesthetically and/or with sealing.

Screwless terminal blocks are UL, VDE approved

UL and VDE approved screwless terminal blocks can now be supplied boxed in 36-way bundles with 10 end plates enabling users to create banks of terminals to meet their custom requirements.

UL and VDE approved screwless terminal blocks from Camden Electronics can now be supplied boxed in 36-way bundles complete with 10 end plates enabling users to create banks of terminals to meet their custom requirements. Offering maximum convenience, Camden's CSTBV series boxed bundle is available in 5mm and 5.08mm pitch versions and users can simply divide the 36-way stacks into desired lengths, adding end-plates where required. For volume orders, Camden also offers a full customisation service, pre-assembling blocks to individual requirements from single-pole units, spacers and end-plates.

Moulded in grey UL94-V0 flame retardant PA66, the CSTBV terminal blocks feature guided pin alignment, anti-solder wicking and stainless steel springs.

Specifications include 0.3 to 1.5mm2 cable entry, rating of 12A/250V, dielectric strength =2.5kV/60s, insulation resistance 5M ohms and working temperature from -20 to +125 deg C (160 deg C for short periods).

The pin/terminal is 5u tinned phosphor bronze.

Spring-cage plug connectors save time

The SPC 5 and SPC 16 spring-cage plug connectors from Phoenix Contact offer an easy-to-install and time-saving solution for wiring in PCB connection technology.

The SPC 5 and SPC 16 spring-cage plug connectors from Phoenix Contact offer an easy-to-install and time-saving solution for wiring in PCB connection technology. Both plug connectors are designed with a combi/spring, spring-cage connector for direct tool-free connection to the PCB. This spring permits the connection of flexible cables with cross-sections up to 6mm2 and rigid cables with cross-sections up to 10mm2 with the SPC 5 plug connector.

Thus a current of 41A can be transmitted with a 7.62mm pitch.

The SPC 16 plug connector with pitch size 10.16mm also permits the tool-free connection of flexible cables with a cross-section up to 16mm2 with minimal force.

The current loading capacity in this case is 76 A.

Both plug connectors have unrestricted 600V UL approval in use group C and are thus appropriate for use on the international market.

They are compatible with market standard housings and thus offer an alternative to plug connectors with screw connections
