These heads have a black epoxy electrocoat that provides good corrosion- and chemicalresistance; however, it does not provide UV protection for outdoor applications. These heads include a standard graphite material gasket that provides good chemical stability, superior creep resistance and a maximum temperature rating of 825 ºF. Pyromation 340 series terminal blocks or 400 series transmitters and DIN Form B blocks or transmitters can be mounted in these heads.
The 49 series flip-top aluminum connection heads listed below meet NEMA 4 requirements for indoor or outdoor applications. The 49 series flip-top aluminum head utilize an EPDM O-ring seal with a maximum temperature rating of 400 ºF. The flip cover provides easy access to the terminals for wiring or maintenance. These connection heads accept the Pyromation 340 series terminal blocks, 400 series transmitters, and DIN Form B blocks and transmitters.
The explosion/flame proof connection heads shown below are designed for use in hazardous locations. Please refer to page AC-7 for descriptions, specifications and ratings for each head. See the "Overview of NEC Hazardous Location Classifications and Methods of Protection" table in the Explosion-Proof (XP) Sensors section of the Pyromation catalog for complete definitions of ratings.
The 215807 is an aluminum DIN Style connection head with a 1/2" NPT process opening and a 3/4" conduit connection. The second conduit opening is built-in for optional dual access.

The plastic connection heads are molded from white polypropylene and include a stainless steel cap chain and pins. They have been tested and meet NEMA 4X wash-down and corrision requirements for indoor or outdoor use, providing protection against dust, rain, splashing and hosedirected water. The head material is FDA approved for food contact.
These heads come with an O-ring seal providing a maximum temperature rating of 250 ºF. Each head has a 1/2" NPT process opening and a 3/4" conduit opening. They will accept Pyromation 340 series blocks, 400 series transmitters and DIN Form B blocks or transmitters.
These Flip-Top, Die-cast Aluminum connection heads feature an easy-to-open, flip-top cap that is hinged on one side so the cap cannot be lost. These heads come with a standard O-ring that provides good chemical stability, excellent wet/steam sealing characteristics and a maximum temperature rating of 400 ºF. The heads accept Pyromation 340 series terminal blocks, 400 series transmitters and DIN Form B blocks or transmitters.
The miniature nickel-plated connection heads listed below are for indoor or outdoor non-hazardous locations. They provide some degree of protection from dust, rain, and splashing water. The heads come standard with an O-ring moisture seal where the cap connects to the body, and a rubber grommet where the wire exits the cap. The nickel plating provides good corrosion protection. The 362 series connection heads are available with a 1/8" NPT or 1/4" NPT process connections, along with 2-, 3-, or 4-terminal configurations.
