New energy schemes and sustainable mobility strategies will shape the 21st century.

The worldwide demand for energy is growing disproportionately. It is estimated that today‘s energy consumption will increase by another 50 % during the next 20 years - and during the next 50 years it will even double. In future, our society will have to deal with new energy schemes to a far greater extent. A sustainable mobility strategy will take an important role here, especially against the background that in Germany the traffic accounts for approx. 20 % of the total energy consumption.

In its coalition agreement, the German Federal Government has therefore setitself a clear objective and formulatedin its “National Electromobility Development Plan” that it wants to bring onemillion electric vehicles onto the streetby 2020, thus advancing to becomethe worldwide lead market for electromobility.

Pin & Sleeve Devices

Pin Sleeve 60A Back Shell

The 60 amp plug and connector IEC60309 are now available with our new back shell. Previously the new back shell was only available in 20 and 30 amp versions. We are now introducing the 60 amp version available in 3,4, & 5 wire configurations in "splash proof" (IP 44) and "water tight" (IP 67).


Worldwide Interchangeability

 

Walther Electirc Building

Walther's pin & sleeve devices are built to IEC 309-1 and 309-2 specifications and are interchangeable with other manufacturers who conform to the IEC standards and color coding system...anywhere in the world. Manufacturers that do not comply with the standards have their own proprietary configurations and are not plug compatible with other pin & sleeve products. Once you have selected a proprietary configuration you are locked in to a single source. Specifying IEC 309-1 & 309-2 devices provides convenience and flexibility that users have come to accept almost without thinking.

Safety

IEC 309-2 configurations for plugs (or inlets) and receptacles (or connectors) are single-rated which assures proper mating of devices with the same voltage and amperage. It is virtually impossible to couple a plug and receptacle of different voltage and/or amperage ratings.The size of the device is determined by the amperage rating. plugs and receptacles of different amperage ratings are not compatible because of the size variance.Many proprietary pin & sleeve configurations, that do not conform to the IEC standards, are designed to accommodate multiple voltage systems. A plug wired to a piece of equipment designed to operate at one voltage system could unintentionally be plugged into a receptacle wired with an unlike voltage. Mismatching voltages could cause damage to the equipment or even personal injury and is not considered safe electrical practice.The voltage, of single rated Pin & Sleeve devices of the IEC 309-2 type, is determined by the location of the oversized female ground contact relative to the key-way located at the bottom of the housing. A clock face is used to represent the location of the ground sleeve for a specific voltage system. For example, a 480 VAC receptacle or connector will have the oversized ground sleeve located in the 7 o' clock position. The corresponding grounding pin location on the plug or inlet is a mirror image of the female device. Devices of mismatched voltage systems simply cannot be mated. Each device is clearly marked with the voltage system for which it is intended to be used. The diagrams at the links below show the keying position and the color coding that is associated with each voltage system.North American Rating | International RatingThe insulated housing is made from a high impact, nylon material. The nonmetallic device, while abuse and corrosion resistant, is also nonconductive, which enhances the safety of the product.

Plugs and receptacles rated 60 amps and above, feature an "electrical interlock" by way of a pilot pin on the plug and female sleeve on the receptacle that is shorter than the main pins. The pilot pin and female sleeve make contact last, and break contact first. The sequence turns the power on when the pilot pin and sleeve mate, and turns the power off before the phase contacts are disengaged. This prevents making or breaking the circuit under load.

Reliability

Walther offers the widest variety of plugs, receptacles, connectors and inlets, made of the highest quality and design integrity in both splashproof and watertight versions.Watertight (IP67) devices are designed for use in the most demanding environments that require safety, ease of use, reliability and durability. These devices can withstand impact and vibration and provide complete protection against dirt, dust, water jets and even temporary flooding. Watertight devices are available in 20, 30, 60, and 100 amp (North American) ratings and 16, 32, 63 and 125 amp (International) ratings.Splashproof (IP44) devices are suitable and recommended for use in a variety of light industrial environments and provide complete protection against contact with live parts, damaging deposits of dirt and dust and splashing water. Splashproof devices provide many of the heavy duty construction features found in the watertight products, but at a more economical cost. Splashproof devices are available in 20, 30 and 60 amp (North American) ratings and 16, 32 and 63 amp (International) ratings.Watertight and splashproof devices provide exceptional UV stability for superior outdoor performance.All Walther plugs and connectors are supplied with an internal cord clamp designed to firmly grip not only the outer cable jacket, but also the internal conductors. The internal cord clamp eliminates strain on the terminals while providing high pull-out values without external protrusions to snag adjacent wiring or the installer.In addition to the internal cord clamp, Watertight plugs and connectors are also supplied with an external cable gland. This cable gland serves as a secondary method of eliminating strain on the terminals and conductors while assuring watertight performance. Standard splashproof plugs and connectors are also supplies with the same external gland as the watertight devices. However, a cable sleeve, designed to speed up installation, is provided with a lower cost splashproof alternative.All Walther plugs and connectors, furnished with either a cable gland or cable sleeve, meet the cord and cable secureness requirements defined in UL 1682, Section 33.

CEPro Power & Control

POWER plus CONTROL= CEPro

 

Walther Electirc Building

Walther's Advanced series of CEPro connectors combine both power and control, monitoring and sensing contacts in one plug and socket system. CEPro is the trade name for a plugs and sockets system which can transmit both power and control signals simultaneously within one compact system. One instead of two plugs and sockets system – a compact solution. CEPro devices can be plugged and withdrawn under load.

 

This system is ideal for installations and machines which operate or utilise both power and control systems. For example:

  • Production Planning Systems (PPS)
  • Computer Integrated Manufacturing (CIM).

Other applications are for example connection to endusers with netware-backedup systems, like:

  • crane controls
  • light- and stage control
  • container control etc
