PCB terminals made from WEMID for increased safety and performance in higher ambient temperatures
– Enhanced continuous operating temperature of 120 °C – Pitch: 3.5, 5.00, 5.08 or 9.52 mm
– Pressure clamp, clamping yoke and tension clamp connections – Customary pole numbers available in four colours.

Already established on the market for years, Weidmüller is now offering its family of PCB terminals PS 3.5, PM 5.0x, LS 5.08, LM 5.0x, LL 9.52 and LMZF 5.00/5.08 mm in versions made from the insulating material WEMID. These PCB terminals are distinguished by an increased continuous operating temperature of 120 °C. They guarantee increased safety and enhanced performance when operating in high ambient temperatures.

Electronic and mechatronic devices are becoming ever smaller and more complex. This trend leads to an extremely high assembly density of the integrated PCBs and the correspondingly high temperatures to match. It goes without saying that the devices being utilised must function reliably, even in the face of high on-site ambient temperatures. Finding a solution to this problem begins as early as the design stage of the devices and electronics, placing high demands on the quality of the material and the components to be used. PCB terminals made from the highly heat-resistant insulating material WEMID meet the demands cited above with room to spare.

WEMID is a halogen- and phosphor-free special thermoplastic from Weidmüller that

displays an enhanced continuous operating temperature of 120 °C (by comparison PA 66: 100 °C) and improved fire resistance characteristics. The flammability class is VO (PA 66: V2) in accordance with UL 94. Products with an increased continuous operating temperature have the following advantages for the user: on the one hand, the customer can utilise the PCB terminals with the same load current in devices operating in a higher ambient temperature (+20 Kelvin). Or put another way, the same physical size of PCB terminal offers a greater power spectrum and more safety. When seen from the perspective of ‘product liability' the safety aspect takes on particular significance. And on the other hand, with constant ambient temperatures the user can utilise the PCB terminals with higher currents. That means in practical applications that smaller and more economic PCB terminals can be used for the same power spectrum. That means more compact electronics modules and in turn more compact devices can be realised. The new PCB terminals made of WEMID fulfil the specifications contained in the RoHS Directive (Reduction of Hazardous Substances). WEMID is qualified for use in railway applications in accordance with NF F 16-101 specifications.

It does not matter which family of PCB terminals the user wishes to utilise in his applications, he always retains high levels of planning freedom. This is supported by the standard colours: orange, grey, green and black as well as the conventional pole numbers. Equipment can be marked on-site for identification using strips of terminal markers or supplied ex-works with markings printed on them directly. PCB terminal families equipped with a pressure clamp or clamping yoke connection are fitted with a ‘plus/minus' screw as standard for reliable operation and transmission of the required torque. Conventional flat-bladed or Pozidrive Z cross-headed screwdrivers can be used at the user’s convenience for screw connections with a ‘plus/minus’ screw. That means that ‘plus/minus’ screws also allow power-operated screwdrivers to centre more easily.

With its new PCB terminals made of WEMID, Henskes is offering its customers a programme of products that is distinguished by its suitability for a wide spectrum of applications and enormous flexibility.
