Adjustable Resistor,Sliding Rheostats SX7D, 2-8A，12-190Ω

Description of  Sliding Rheostats：

The SX7D series adjustable resistors can be powered with about 65% of the corresponding nominal load of the fixed types with corrugated wire for extra high demands on surge or pulse load. They are wirewound enameled or cement coated resistors with an open area along the resistors where the resistor wire is un-coated. The surface of the ceramic tube are wound wave-shaped alloy resistance wire and a high temperature resistant and fireproof coating are applied.

Key Features of  Sliding Rheostats：

1.Long term high stability
2.non-inductive or inductive type options
3.high operating voltage(up to 1.2KV) and high power ratings(up to 15KW)
4.terminals suitable for soldering or bolt connection
5.Available covered in stainless steel AISI 304. Case made in zinc plated steel or in stainless steel or in aluminum plated steel if requested.
