Albright SW206-20M magnetically latched 24VDC 250A contactor with armature extension and a standard red knob, intermittent.
- The SW206 series of contactors has been designed for direct current loads, particularly motors as used on larger electric vehicles such as industrial trucks, airport tractors, etc., they have double-breaking contacts with Silver-alloy contact tips, which are weld resistant, hardwearing and have excellent conductivity.
- The contactors are compact in size and are fully serviceable, with a range of spare parts available.
- Auxiliary switch kit part number: 2155-202.
- Armature extensions are fitted with a standard red knob.
- 2-Off 2155-165 ‘L’ Shaped bracket kits fitted.
- Magnetically latched contactor, yellow warning label fitted.
- 1 'Normally Closed contact on the left-hand side front, 1 'Normally Closed' contact on the right-hand side rear.
About Intermittent (Int.) SW200 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 SW206 has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW206 is suitable for switching Resistive, Capacitive and Inductive loads.
The SW206 features single-pole, single-throw, double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW206 has M10 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or steel mounting brackets (2155-165 brackets are fitted as per image).
Magnetic Latching: The contact position is secured with the use of a permanent magnet within the assembly. The coil requires a pulse to close the contacts, and a reverse polarity pulse to operate the armature and open the contacts, but otherwise remains in the last energised state without the need for power. It should be noted therefore these are not failsafe.
| Interrupted Current: The opening and closing on load with frequent switching (resulting in increased contact resistance). |
| Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance). |
