Specifications
General specifications
Enclosure
304 folded stainless steel
Temperature range
-40°F to 180°F (-40°C to 80°C)
Environmental
Hermetically sealed contact switch
Encapsulated in polyurethane
NEMA rating
1, 2, 4, 4X, 5, 12, 12K
Protection class
IP 66
Response time
1 msec (5.4VA); 10 msec (150VA)
Individual circuits
The two circuits do not switch simultaneously,
and depend on the speed of the guard
closure. Based on closure speed of 1' per
second and a gap of 1/8", a delay less than
50 msec is typical.
Life cycles
100,000 under full load;
Up to 200,000,000 under dry circuit
