 SW84B-7 single pole, double throw solenoid contactor with magnetic blowouts, 48V intermittent.

  • The SW84B-7 has been designed for 48V direct current (DC) loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW84B is suitable for switching Resistive, Capacitive and Inductive loads.
  • They are economical in price and compare favourably with sealed automotive style solenoid switches which cannot be serviced or inspected for contact wear.

Associated Products

  • 2070-193 Service or repair contact kit.
  • 2070-124 Auxiliary microswitch kit.
  • 2126-48A Mounting bracket.

Dimensions

  • Height including terminals and coil base cap: 91mm.
  • Coil width: 40mm.
  • Cap width: 39mm.
  • Coil and cap depth, including fixed contact bars: 58mm.

Magnetic Blowouts

 These contactors are fitted with magnetic blowouts (denoted by 'B' suffix in the SW84B range) across contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. Fitting of blowouts can make the contacts polarity sensitive and the positive markings on the top cover of the contactor must be observed.

About Intermittent (Int.) SW84B-7 Solenoids

 Intermittent contactors by design are predominantly used for hydraulic functions on vehicles, they make and break quicker than continuous solenoids and are not recommended for prolonged contact periods.

 The SW84B has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M4 tapped holes or mounting brackets purchased as separate items. Mounting can be horizontal or vertical, when vertical the M8 contact studs should point upwards. Please note Normally Closed contacts are not suited to make and break load.

Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance).
Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
