This is the enclosure for the Encapsulated Mini RTD PT100 Transmitter and also Solid State Relays – SSR.
Potted, Encapsulated in epoxy, hermetically sealed. It has a Nickel Plated Aluminum Plate insert molded. For removing heat from BTA41600.
The plastic is a fire retardant high temperature grade. The epoxy is ciba araldite, fine alumina is filler. A transparent terminal cover for safety. It costed me an equivalent of 600-700 USD for tooling plastic parts.
