The OSID-EHE is made of ABS. The glass window causes minimal attenuation of the UV and IR beams. Installation and servicing is extremely easy. The imager housing has two glands for easy wiring. The Emitter housing can be used with both battery powered and 24V wired emitter. To access to the Imagers FTDI socket the lid needs to be removed. A separate cable inlet directly below the FTDI socket is normally sealed but can be fitted with an additional gland supplied with the enclosure for servicing or upgrading the imager.
