 Albright International SW250-1111M 24 volts DC single-pole, single-throw (SPST) magnetic latching solenoid contactor, intermittent.

  • The SW250 is designed for use in telecommunications and power distribution applications where an uninterrupted current load is switched.
  • These contactors are primarily for use with Direct Current loads but can also be used with Alternating Current if used in conjunction with an AC rectifier board (sold separately).
  • The SW250 features double-breaking main contacts with Silver-alloy tips, which are weld-resistant, hardwearing and have excellent conductivity.
  • Silver plating on the main contacts is standard for the SW250.
  • Bi-directional diode fitted across the left-hand side.
  • Uses extended armature with a black knob wound on top of the thread aspect.

Dimensions

  • Height including terminals and coil base cap (excluding armature extension): 79mm.
  • Coil width: 40mm.
  • Cap width: 49mm.
  • Cap and fixed contact width: 89mm.
  • Fixed contact depth: 38mm.

About the Intermittent (Int.) SW250 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 SW250 is a compact contactor which can be busbar mounted vertically or horizontally. If mounted vertically, the coil should be at the bottom.

Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
