Electrical Circuit Types
The document defines several electrical circuit configurations identified by letters:
- C - SPST (Single Pole Single Throw) Normally Closed (NC)
- O - SPST Normally Open (NO)
- D - SPDT (Single Pole Double Throw)
Electrical Connection Types
Connection types are coded numerically and include:
- 1 - Wire type
- 2 - Blade type
- 0 - Other (rod/barb)
Pressure Connection Types
Pressure connections are specified by thread or tube types with corresponding codes:
- 2 - M thread (below M10)
- 3 - M thread (above M12)
- 4 - NPT thread
- 5 - R thread
- 6 - G thread
- 7 - UNF thread
- 8 - Copper tube
Interface Material
The interface material is coded as follows:
- 1 - Stainless steel
- 2 - Brass
- 8 - Copper
Summary
This document provides a coding scheme for specifying electrical circuit types, electrical connection types, pressure connection types, and interface materials. The codes facilitate standardized identification and selection of components based on their electrical and mechanical connection characteristics as well as material composition.
Catalog excerpts
LF08AHigh current Pressure switch The LF08A switches are fixed set point, factory calibrated pressure switches. It is automatic reset, and can be normally open or normally close contacts. All metallic wetted components make the LF08A switch compatible with a multitude of chemicals in liquid or gas form. It is offered numerous types of electrical terminations from different size and style push on terminals to wire leads with an array of standard industry connectors. In house machining capabilities allows Lefoo to offer a wide variety of pressure fitting from different thread types and sizes to units with internal deflator and cupper tubbing for sawing operations.
