Turck Standards

One or more of the following standards may apply to products or components of products in this catalog. This section is intended to provide a reference to the applicable standards only. Original or facsimiles of the original standards documents should be used for interpretation. It is the responsibility of the user to determine the suitability of use of the products represented in this catalog.

ANSI/B93.55M

Generally defines the geometry and connection scheme of “mini" type connectors used in fluid power (valve) applications. It defines the numerical marking of the pins and the conductor size and colors for 3 and 5 pin versions. This specification was the basis for the so-called “automotive" standard conductor colors that are widely used on sensors.

CENELEC EN 50 044

Identifies connections for inductive proximity switches. The specification defines conductor colors for proximity switches with 2, 3, or 4 conductors. It also defines numerical marking of the terminals, whether quick disconnect, or not. Turck sensors and recommended cordsets that apply within the scope of the standard comply with CENELEC EN 50 044. The conventions defined in this standard have been widely adopted in industry to include photoelectric controls and other related sensing devices.

CSA

The Canadian Standards Association is a not-for-profit membership-based association serving business, industry, government and consumers in Canada and the global marketplace.

Is the CSA mark valid across America?

Yes. CSA International is accredited by the Occupational Health and Safety Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL). The CSA tests to the same American industry standards as other accredited laboratories, regardless of who authored or published the standard. CSA marks are recognized and accepted throughout America by federal, state
and local authorities.

DIN 43650

Defines the geometry and other characteristics of the “square" connectors most frequently used on hydraulic and pneumatic solenoid valves and other devices in the fluid power industry.

MSHA

The Mine Safety and Health Administration - a US Government agency that ensures and regulates safety for mines and mine workers. The MSHA approval is required for products used in underground mines, including electrical equipment, power cords, and instrumentation components.

The MSHA standards require special fire-resistant properties and characteristics that prevent the propagation of flames.

IEC 61076-2-101

Defines the geometry and other characteristics of the M12x1 family of threaded connectors used to connect control and measurement devices in industrial environments.

IEC 61076-2-104

Defines the geometry and other characteristics of the M8x1 family of threaded and snap connectors used to connect control and measurement devices in industrial environments.

NRTL

Nationally Recognized Test Laboratory - An independent laboratory authorized by the US Government to perform product safety evaluations. Test laboratories must meet government laboratory standards, and are audited annually by OSHA to maintain this credential. UL standards are adopted by the US government and OSHA as being “Safety Standards", and these accredited labs then use the UL standards to perform product evaluations.

The Canadian Standards Association (CSA) is authorized as a NRTL to perform product evaluations and tests to the UL Standards. The certification mark “CSA NRTL/C" is then applied to products that satisfy all construction and performance criteria for both US and Canada. This certification mark is generally accepted by local building, safety, and quality agencies as meeting safety, construction, and performance criteria in both the US and Canada.

RoHS (Restriction of Hazardous Substances in Electrical and Electronic Equipment)

In Europe, the RoHS directive is the legal basis for the ban of certain materials (lead and other specific heavy metals) in electric and electronic products. This directive was adopted and implemented in Europe as of July 1st, 2006.

This directive is geared towards high volume consumer goods. Turck is not required to adopt the directive, but is affected by the legal requirements which prescribe that only lead-free products and components to be sold in Europe. Turck, however, is engaged in testing lead-free soldering and substitute substances/components in support of our commitment to the environment. The main issue we had to overcome to become RoHS compliant was our solder material that contained lead. We have tested and verified a RoHS approved solder material which was implemented as of May 1st, 2006 and a RoHS logo will be added to bag labels for those parts. Please be aware that there are certain products like PCBs and ITC/PLTC cable that will continue to contain restricted substances.

Shielded Cordsets

Whenever wire is used to transmit electrical data, it is possible for the wire to absorb external noise, possibly changing the characteristics of the electrical signal, or to give off noise that could cause changes in other electrical components that are near. Shielding is the act of placing conductive material between the potential noise emitters and receivers.

Electrical noise is usually classified as electro-magnetic interference (EMI) or radio frequency interference (RFI). Turck offers a number of shielding options:

1. Foil shield with drain, drain not connected

TURCK Connectivity Product Standards

2. Foil shield with drain, drain connected to a pin

TURCK Connectivity Product Standards

3. Foil and braid shield with shield tied to coupling nut

TURCK Connectivity Product Standards

4. Aluminum armored cable with armor tied to coupling nut

TURCK Connectivity Product Standards

For a shield to be effective, it must be tied to a ground at some point. It is usually preferred to not tie the shield to ground at more than one point to avoid ground loops. A shield not tied to a ground will reflect some noise and is better than no shield at all, but will be much more effective if tied to a ground.

High frequency noise, RFI, is handled well with a foil shield. The wavelength of RFI is usually small and can pass through the 'holes' in a braided shield. EMI is usually larger wavelengths and needs a braided shield to increase the mass of shielding material to be effective.

Aluminum armored cables provide the ultimate in noise immunity as they are basically flexible conduit.

Select the shielded cordset that best meets your needs. If it is easier to tie the shield to ground inside the panel, the foil/drain with the drain not connected inside the cordset is a good choice. If you can connect the drain via a pin inside the device being connected, the foil/drain with the drain connected to a pin is a good choice. Any environments with EMI noise from things like large motors or welding equipment will benefit from a braided shield tied to the coupling nut.

Turck shielded cordsets with the shield tied to the coupling nut offer complete shielding for the entire length of the cordset. A metal sleeve inside the molded body connects the braid/foil shield of the cable to the metal coupling nut with no loss of shielding potential.

Turck armored cordsets are the ultimate in shielded connectors. A Turck patented process allows the interlocked aluminum armor to be connected directly to the coupling nut offering the same protection as running conductors inside metal conduit.
