Compact SR Safety Key Switch to Isolate Power
isolating power to machinery. For example, when the key is trapped inside the SR unit the power to machinery is on, and when the key is free, power is off. This allows the person carrying the freed key to enter the machinery or guarded area safely and power is not resumed until the key is returned. This is a typical sequence and other sequences can be specified. The key switch is heavy duty, housed in a metal enclosure which is IP rated 65/66/67. Its compact design allows the customer plenty of space for wiring, a feature not available in previous switch offerings. The switch current is 20A. The SR key switch is part of Fortress’ mGard range of safety interlocks. mGard is the premier range of modular trapped key products that are used to safeguard dangerous machines and hazardous processes. Individual modules can simply be added or removed depending on the application which allows flexibility and tailoring. Fortress’ mGard range of products is suitable for use in high risk applications.

Nordson EFD PICO™ Jet dispensing system
Combines High Production Speed and Exceptional Accuracy
• Dispenses a wide range of low to high viscosity fluids • Can apply consistent shots as small as 2 nanoliters at speeds up to 150 dots per second • Combine high production speed with exceptional accuracy and process control • Ideal for high-speed, high volume applications that require many small, precise fluid deposits. • Ideal for use on uneven substrates or hard-to-access areas
• Huge range of possible applications: electronics (bonding cell phone speakers with UV-cure adhesives), life sciences (attaching needles to medical syringes), and precision mechanical applications (jetting small amounts of grease on micro gears).
• Easy to set up on Nordson EFD’s automated desktop and in-line dispensing systems three or four axis for simple programming of dots, stripes, arcs, compound arcs and patterns on different planes.

New PZ6 Roto L ensures secure and flexible crimping using only one tool
cabinets. Designed for professional use in both industry and manual trades, it guarantees consistently high-quality and precise crimping results using only this single tool. The crimping of wire-end ferrules usually requires individual crimping tools, along with matching contacts. However, Weidmüller provides a wide range of high-quality, wire-end ferrules with the PZ6 Roto L crimping tool, ensuring that users are able to achieve faultless crimping results and undertake a vast range of requirements using this one tool. Incorporating a flexible and a fixed crimp insert in a single tool also eliminates the need for time-consuming tool changing: Indeed, the PZ 6 Roto L allows the crimping of lines and wire ferrules (with and without plastic collars) for the entire cross- section range from 0.14 to 6.0 mm² (AWG 24–10), without the need for any other tools. The PZ6 Roto L is also equipped with a secure
T
automatic stop which prevents the tool from being accidentally opened during the crimping process and helps to prevent time-consuming and costly, faulty crimping. The automatic stop can be released at any time if there is a malfunction. In operation, the PZ6 Roto L has a unique combination of an adjustable crimp insert with a fixed locking mechanism. Lines and wire-end ferrules can be simply inserted into the tool either from the front or the side, significantly reducing the effort involved. In addition, the PZ 6 Roto L crimp insert is designed to rotate and can be
locked in two positions, which prevents the crimp insert from being accidentally rotated during the crimping process. This means consistent, high-quality and

accurate crimping results are achieved each time and it can be used in a whole range of diverse applications. Weidmüller uses its own Omega spring system in the crimping tool which means problem-free processing of various wire cross- sections and uniform distribution of the force across the whole tool. This means highly reproducible crimping results are achieved as well as durable tools. The PZ 6 Roto L also has an excellent, ergonomic handle design. This, along with the material and surface structure of the handles ensures safe, comfortable operation. Added to this is the ease of processing at the highest level: 20 percent more crimping force with 20 percent less manual force. The handles have a striking two-colour design and their so-called hard/hard combination is particularly advantageous if oil or other lubricants stick to the handles. This means wire-end ferrules with or without plastic collars can be easily processed. The pull-out forces far exceed the values stipulated in DIN VDE
0660 T. 100 and EN 60947-1/A11. The requirements of crimped connections are
specified in DIN EN 60352-2. An essential quality criterion is the tensile strength achieved for the connection, as well as the avoidance of typical crimping errors. Weidmüller crimping tools and wire-end ferrules are aligned to one another in accordance with the standard and guarantee a consistently high processing quality. Weidmuller also carries out continuous quality assurance processes to ensure high quality standards, such as the service life test, for example, during which the crimping tools must achieve a minimum of 50,000 crimping cycles with uniform quality. Many Weidmüller tools exceed this standard requirement and all Weidmüller hand-held crimping tools are also designed in compliance with DIN 41 641 Part
1.Besides the new PZ 6 Roto L crimping tool, Weidmüller provides KT8 quality tools for the convenient
cutting of copper and aluminium cables, stripping tools for all types of cable, as well as a wide range of wire-end ferrules and cable connectors.
