Devices within the TLM Series are available in multiple styles and pitches to offer designers optimum flexibility in design and the possibility of saving valuable PCB real estate.
Just a short description of a few of the terminal blocks within the TLM Series illustrates the breadth of this comprehensive series. The TLM250C is available from 2-pole, has a sprung screwless push wave design with long pin close to the side cover. On a 2.50mm pitch, rated voltage is 250V, rated current 2A and minimum wire size AWG20. The TLM250D models are the short pin close to side cover equivalent, again rated for 2A/250V. The TLM900R is also available from 2-pole, with a sprung screwless pushbutton wave horizontal 2.54mm pitch design which is end stackable. Rated voltage is 150V, rated current 2A, with wire sizes 26 - 20AWG (0.2/0.5mm²). An equivalent vertical model, the TLM900V is available too. On a 3.50mm pitch, the TLM002C and TLM002D are 2 pole spring screwless pushbutton Wave designs with either long pin close to side cover or short pin close to side cover. The single row, design is rated 250V, 2A, with a wiring orientation of 135 degrees wire to board. The TLM-302R screwless push button design on a 5.08mm pitch offers rated voltage of 300V and rated current of 10A in 20 – 14 AWG size. The design is 180 degrees wire to board.
Three new 300V 15A devices with 2 – 24 poles, designated TLM-203B, have now been added to the TLM Series which will continue to be expanded, with new models currently in development. The three new TLM-230B models are available in 5.00mm, 7.50mm and 10.mm pitches, with rated voltages of 300V, rated current of 15A for wire ranges between 28-12AWG(0.2-2.5mm²).

Time-saving “everything supplied” kit; suits corrosive and hygienic environments; six sizes available
Hylec-APL, the specialist supplier and manufacturer of electrical and electronic components and enclosures, today announces its new DEDSS Stainless Steel Series of lockable, solid door enclosures specially designed to provide high-quality, secure, cost-effective protection for specialist and demanding electronic and electrical installations. The DEDSS Enclosure Series is IP66 rated and protects contents against water and dust, as well as being able to withstand impact to IK10 specifications and extremes of temperature ranging between – 20degC and +55degC. Suitable applications for DEDSS enclosures include corrosive environments, such as the chemical and petrochemical industries, and environments where strict hygiene is required, for example, the agro food sector.
The rugged DEDSS enclosures range is manufactured from grade 304 stainless steel and supplied as a complete kit. This includes a metal lock and key, a 2mm galvanised steel back plate, and external mounting feet and spacers. In addition, DEDSS enclosures come complete with an earth strap pre-wired and fitted between the door and the housing to save valuable installation time.
This comprehensive range encompasses six different sizes, ranging from 300mm high x 200mm wide x 150mm deep to 500mm high x 500mm wide x 200mm deep, so offering a wide choice capable of accommodating most installations.

Hylec-APL, the specialist supplier of electrical components and enclosures, announces new model in its range of Isolator switches, which provide fast electrical isolation for multiple applications, including industrial machinery, commercial buildings, power supplies, security equipment and HVAC. Isolator control switches are IP67 rated and withstand water up to a depth of one metre, as well as completely preventing the ingress of dust and dirt, vital in many factory and commercial applications.
Safety is of paramount importance in such environments, and Isolator control switches ensure an electrical circuit is completely de-energised for routine service and maintenance and can be shut down quickly in the unlikely event of an emergency. The Isolator switch separates the circuit from the main power source and discharges any current trapped in the circuit, rendering it safe to work on and of course ensuring fast shut down and the absence of any electrical current when an emergency stop is required. When used as an emergency stop, it can be locked in the off position using a padlock (not supplied). For safety, the switch is interlocked with the lid to prevent opening while in the “on” position. The interior mechanism is a 4-pole rotary isolator switch disconnector used to switch power to commercial or light industrial applications.
Isolator control switches are manufactured from completely flame retardant polycarbonate, rated to UL94V-0, providing an additional margin of safety over competitive products with a lower flame-resistance rating. As well as being flame retardant, housings are robust and highly visible, with yellow covers and red control switches. The new 80A AC Isolator model features silver-plated alloy contacts for high reliability. Earth terminals are included, as well as captive retained cover screws. The 80A AC Isolator has a compact footprint, but its internal dimensions are a generous size, measuring 9cm wide by 17.3cm long, so there is space to manipulate cables easily during installation.

IP68/IP69 rated; 10A – 400V AC/DC; 80% quicker to install; 14mm diameter
Hylec-APL, the specialist supplier of electrical components and enclosures, announces the launch of the new TeePlug® TH381 plug and socket electrical micro connector designed for underwater use and harsh environment installations. Offering the highest levels of reliability, TeePlug TH381 Series connectors provide complete protection against the effects of permanent submersion in water to ensure electrical connection, even when subjected to high pressure water jets. The IP68/IP69K rated TeeTubeTH381 models also prevent dust and dirt ingress. Measuring only 14mm in diameter, the TeeTubeTH381 Series suits outdoor lighting applications, such as architectural lighting, street lighting, underwater lighting, illumination of road signs and billboards and the connection of interior and exterior Class 2 electrical devices.
TeePlug TH381 connectors feature a push-pull design that installs up to 80% faster than competitive waterproof connectors, saving valuable time on-site and reducing cost. Intuitive and functional in use, TeePlug TH381 connectors incorporate a special coupling system that confirms correct alignment and mating with an audible click and also prevents accidental disconnection, even against opposing forces of 25kg (8Kg according to EN61535). Models with an additional optional safety system are available to further protect against disconnection by requiring the use of a tool such as a flat-blade screwdriver for uncoupling. TeePlug TH381’s IP68 water resistance rating is guaranteed even when subjected to bending forces of up to 5Kg, and they are resistant to high pressure water jets up to 100Br, 16l/min at a water temperature of 80degC. Vibration and external mechanical stresses are no problem either, as cable traction is prevented up to a force of 8Kg.
Electrical specification is 2-poles, 10A – 400V AC/DC. Wire section is 0.25mm² to 1.5mm² without ferrules. TeePlug TH381 Series plugs and sockets are available in two variants, cable to cable and panel-mount, and in two sizes to suit cable diameters between 5.8mm and 6.9mm and 7.0mm – 8.0mm. Cable reduction grommets are available for smaller cables, as are additional accessories, including sealing caps, a dedicated spanner for quick, safe installation, a bigger cable gland for larger cables and a rear nut for panel-mounted installations.
Building on the heritage of the proven TeePlug range, the new TeePlug Series TH381 is the optimum electrical connector for all submerged and challenging installations.
