luke Process Instruments has launched the Thermalert 4.0 spot pyrometer series for automatic noncontact


temperature monitoring between -40 °C and 2,250 °C. The series currently comprises 13 models with varied spectral responses, including dedicated sensors for metals, glass, and plastics products. A large choice of optics is available for long and short focal distances. Due to the outstanding ambient temperature range of -20 °C to 85 °C, more measuring points can be set up without cooling accessories and without installing cooling media supplies. The rugged IP65 infrared thermometers exhibit best-in- class repeatabilities, response times, and accuracies. The system software supports remote configuration, monitoring, field calibration, and firmware updates. These functions can significantly lower service costs and time spent on setup and troubleshooting. Plug & play operation further facilitates installation and maintenance. The sensors feature galvanically isolated analog and RS485 interfaces. Up to 32 devices can be connected within an RS485 network. The manufacturer will keep on adding fieldbus and feature options in future.

RTS stands for "Reflowable Thermal Switch". It was developed to protect highly integrated power semiconductors like MOSFETs, ICs, IGBTs, Triacs, SCRs, etc. from overheating. Before mechanical activation, the RTS can be mounted using conventional reflow soldering techniques with temperature profiles up to 260 °C.


Mechanical activation


After having the RTS reflow soldered on a PCB, mechanical activation arms the RTS for tripping at 210 °C. This activation can be done manually or by fully automated means. In contrast to electrical activation, the RTS activation status is clearly and immediately visible to the installer. Furthermore, the third additional contact required for electrical activation is thereby eliminated.


Compact dimensions, high load capacity


The new type of overtemperature protection shines with the smallest dimensions and highest load capacity. Operating currents up to 100 A at rated voltages of up to 60 VDC can be handled by the RTS, which is just 6.6 x 8.8 mm in size. Customer-specific variants are available with an integrated shunt or an additional overcurrent fuse. These further integrated functions are resulting in less space consumed on the printed circuit board. The Reflowable Thermal Switch meets the high reliability requirements of AEC-Q200 and MIL-STD.


Protection against thermal runaway


Thermal runaway refers to the overheating of a power semiconductor due to a self-reinforcing, heat-producing process. The reasons for this are the ever increasing power density and the trend towards miniaturization of electronic circuits.


RTS protects power semiconductors not through a logic circuit but rather through basic laws of physics. In case of a thermal runaway, the RTS reliably interrupts the circuit precisely at the well-defined temperature.

CHURTER introduces its new RTS. The RTS is a particularly compact overtemperature protection device


ne free USB port is all that is needed to drive an extra display and touch


with the new usb display and touch driver board from RDS. Two versions are available the 7”,


1024x600 and the 10.1” 1280x800 both of which come with the option of a PCAP touch sensor. Audio input for remote applications requiring sound is available and, as power is over USB, standard brightness is possible.


Options include kit, panel mount or chassis mount and should you require an alternative display size and custom integration then these are also possible

New Lid Options For ROLEC’s IP 67 aluCASE Enclosures


R


OLEC has added new options to its aluCASE range of diecast aluminium enclosures: transparent lids,


integrated hinges and a console adapter for desktop use. Smart modern aluCASE is ROLEC’s premier ‘go


anywhere’ enclosure for industrial electronics. It can be mounted on walls, machines, bulkheads and desks. All aluCASE enclosures can be installed ‘lid closed’ to


safeguard the electronics and seal – ideal for challenging environments. The fixing and lid screws are hidden beneath clip-on trims, protecting them from the elements and enhancing the aesthetic appearance. The lid is recessed to accommodate a membrane


keypad, front plate or product label. Most aluCASE models are available with polypropylene


(PP) lid retaining straps. New integrated hinges for heavier loads can be mounted on either narrow side of the enclosure. These hinges have concealed fixings for superior strength, resilience and aesthetics.
