AR04BK* is an EN50131 Grade 3 push fit, single reed flush contact, in Black materials for those niche / bespoke / high value projects.
(*Note: Add resistors required to end of partcode)
This contact is designed in such a way that magnetic interference from surrounding metals is reduced, allowing it to be used in steel framed doors.
The barrel of this contact holds 4 sloped crush ribs – allowing it to easily slide into a 20mm diameter recess, locking at the contact plate.
6 core wiring allows this contact to be used with both, either or none of the included resistors.
Magnetic Interference Detection allows it to meet the standards required for Security Grade 3.
