A complete electronics design service was required with the key considerations being electromagnetic compatibility, use of a robust enclosure, ingress protection and challenging thermal considerations. Space limitations within the enclosure meant the design would need to be as simplified and compact as possible, and the finished unit needed to meet IP67 rating requirements.
Meticulous selection of components with low levels of high frequency noise, and analysis of each design element from class of power supply to cable termination and component placement facilitated low electromagnetic emissions. An IP67 rated enclosure from our sister company, Deltron Enclosures was selected, and the electronics design was optimised for space utilisation. To prevent a build-up of heat in the enclosure, a heat transfer method was integrated with a solar shield to ensure the unit would operate within temperature limits, even under prolonged and direct sun exposure. Once the prototype had been developed, our engineers performed pre-compliance EMC and ingress protection testing. The unit passed both test and was confirmed to meet relevant industry standards.
The client now possesses an efficient and reliable ANPR traffic camera system. Low-level emissions provide assurance of uninterrupted operation, and long maintenance intervals are ensured due to Roxburgh engineering and validation within an Accredited Test Lab. The client can now submit the device to the Department for Transport with confidence of successful approval.
