Enclosures
Verotec and mass spectrometry is a great match
H
aving originally been approached by a major manufacturer of mass spectrometers to replace a previous supplier and manufacture a design to print enclosure, Verotec designed and manufactured a much improved alternative, based on its standard HD167 subrack family. The new application- specific enclosure offers reduced installation time for the housed electronics, improved EMC screening, better thermal management and greater mechanical protection, all achieved at a reduced cost. The unit is at the heart of the mass
spectrometer, housing the instrument’s controller. Given its physical location in an environment subjected to high intensity ionising radiation, EMC screening is a critical requirement to ensure reliable operation. Solid side plates and top and bottom ventilated covers combine an 80 per cent open aperture ratio for ventilation with effective attenuation. The unit is a 6U high, 32HP wide KM6-HD card cage, fitted with 19” mounting angles and configured as four 5HP slots and a single 12HP one. Four different designs of EMC screened front panels and a plain EMC blanking panel are supplied as part of the unit. The backplane, supplied by the customer, is only 1.5mm thick; it mounts as normal on the rear tiebars and it extends below the card cage to give an I/O area fitted with multiple Min D connectors. A solid rear cover provides both EMC shielding for the backplane and provides it with mechanical support; an additional separate front cover
ROLEC’s aluminium handCASE now offers four variants R
OLEC’s handCASE metal enclosures for handheld industrial electronics are now available in four variants. High performance handCASE is designed for mobile control applications in challenging environments. These diecast aluminium cases are light and comfortable to hold for long periods but tough enough to withstand extreme working conditions. Two base versions are available: one closed for external power supply; the other with an ABS battery compartment (4 x AA or 2 x 9V). Each base can be specified with a choice of two lids, both recessed to accommodate a membrane keypad or product label. There are threaded screw bosses in the base and lid for the installation of PCBs.
Robust handCASE is manufactured
protects the Min D connectors. Conductive gaskets ensure ground continuity through the unit, the large cable aperture through the rear panel is also fitted with an additional external EMC cover once the cable is installed. Three 80mm top- mounted 80mm intelligent fans provide managed cooling. This project again demonstrates the advantages in terms of time, cost and performance of creating a custom design from a standard product platform.

from diecast aluminium for the ideal balance of strength and lightness. It is rated IP 66 as standard. IP 67 ingress protection is optional. The enclosures are available in three sizes – 180 x 80 x 42.4 mm, 220 x 100 x 42.4 mm
ROLEC provides a choice of recessed lids for handCASE (IP 66/67)
and 220 x 100 x 62.4 mm – with silver metallic lids and black (RAL 9005) bases as standard. Prices start at £62.
Accessories include: a holding clip (which can be used with a strap); a wall bracket for clip fastening; a carrying strap with protector; cable glands. ROLEC can supply handCASE fully customised ready for the installation of PCBs. Services include CNC machining, custom colours and materials, printing, engraving, EMC shielding, membrane keypads and full assembly.
