Hydraulic System Products (HSP) has expanded its range of pressure and vacuum operated switches, meeting the needs of a wide range of applications including hydraulic, pneumatic, instrumentation, manufacturing and scientific.
HSP switches are all based on well proven design principles, with models for actuation by rising pressure, falling pressure, differential pressure or vacuum. These are diaphragm type switches operating in various ranges. The actuation point can be set anywhere within the specified range either at the factory prior to shipping or by the user in the field. Switching is via high quality 5A snap action micro-switches using 12/24V DC or 240V AC electrics. Electrical connections are 500mm flying leads, DIN plug or DIN cable clamp.
Standard body material is steel which is zinc plated and passivated for excellent environmental protection. 316 stainless steel is optional. Medium connection is either 1/8in BSPF or 1/4in BSPF male thread. Standard diaphragm material is Nitrile with EPDM or Viton options for media compatibility. Rugged construction, vibration resistance and IP65 protection are standard features for all switches.
