Pressure Switches & Transducers

LFS02
Designed as an economical interface between pressure systems and Printed Circuit Boards.
Can be used as a gauge or differential pressure switch with almost no hysteresis. It is applied to detect both positive and negative pressure
Features include body design that allows the pressure ports to be rotated. Various terminal styles including flying leads available
LFAS
Pressure cut-off switch offering exceptional thermal and dimensional stability at high temperatures.
Suitable for use in contaminated atmospheres; e.g. combustion flues
Designed to meet the low pressure, high temperature specifications of fanned gas and similar appliances, where differential pressures form part of an integral control system
LF31
Pressure, vacuum and differential variations are available, capable of sensing very low set points and switching current up to 5A resistive and 2.5A inductive
Designed for use in HVAC applications, where reliable air proving is critical to both performance and customer safety, the LF31 is particularly suitable for use in gas-fires and water heaters
Smaller and lighter than any other HVAC pressure switch, the LF31 is built for the same temperature range and operating life as conventional switches
The LF31 will perform equally well in other applications which demand low OEM unit cost, robust design, set point accuracy, and high reliability
LF25
Designed for pressure control, with higher current capacity, the LF25 provides SPST or SPDT contact form and switch dead band (also referred to as mechanical differential or hysteresis)
It incorporates high-quality miniature snap-action switches, which are diaphragm operated. The diaphragm material can be selected for the operating medium, temperature range and other parameters.
During the development of a specification, actuation point can be adjusted by the designer, with factory setting required for production
LF32
Capable of sensing very small changes in pressure, the LF32 switch is widely used to control flue aeration and to monitor fans in air conditioners.
It is also suitable for over-heating and frost protection in industrial cooling systems. Its design allows the set point to be seen and easily adjusted by the operator.
