Data Sheet

SM-226LQ: UL-listed. N.O. Contact with ABS plastic
Magnet Housing, and "L" Bracket Magnet Mounting.
ALARM CIRCUIT: For closed circuit alarm systems
only.
REED SWITCH: Gold under-plating with
DEACTIVATED RHODIUM outer-plating.
SECO-LARM contacts have a unique RHODIUM
plating which has gone through a special oxygen
treatment to DEACTIVATE the surface, thus
eliminate the absorption of organic impurities,
polymer growth during operation, and the possibility
of contact freezing.
SWITCH HOUSING: Weatherproof die-cast aluminum
constructed for surface-mounting on garage floor;
able to withstand heavy vehicle pressure without
damage. The switch is safely enclosed in an epoxy
compound. A 24" flexible armored cable gives
complete protection to the switch wiring.
MAGNET: Extra-strength Alnico 5 magnet allows a
2-1/2" operating gap.
MAGNET HOUSING/MOUNTING:
Magnet is housed in a high-impact weatherproof
ABS plastic case and mounted on a garage door
with an "L"-shaped bracket which minimizes the
effect of steel doors on magnets.
CONTACT LIFETIME: 50 million cycles.
RATING: 0.1Amp./100VDC (max.)
1Amp./10VDC (max.)
10W (max.)
TEMPERATURE: -15

On wood surfaces the magnet housing shall be
installed at least 1/4 in. from the switch housing to
comply with UL 681 Installation requirements.
