Surface Magnetic Contacts
Knight Fire & Security Products Ltd surface magnetic contacts range is huge! We manufacture the basic 2 or 5-terminal favourites, potted contacts, mini-surface, aluminium, heavy duty, normally open door contact, double door contacts and wire/cable versions.
If you do require contacts for double doors, then most of our Grade 2 and all of our Grade 3 range is suitable. Please see individual products for further detail.
Our Grade 3 door contacts include biased versions of many of the standard ranges, but also versions which have selectable resistors such as YEND74 (large 2-reed with magnetic interference detection) and YEND24 which is the same size as a standard surface. Due to their selectable resistors, both can be used with all mainstream UK control panels.
For a larger G3 contact for busy exit doors including say schools / prisons etc… try the YM10. G2 version is the M10.
