LJJ4 cold metal detector
The cold metal detector (LJJ series) is mainly used in metallurgical systems to realize on-line detection of on-site (opaque) objects and to detect cold and hot metals.
Working power supply: AC220V/DC24V
Emitter light source: infrared LED / red LED
Detection distance: Opposite (LJJ4-M): red light -12m, infrared light -25m,
Reflection (LJJ4-P): RF35: red light - 8m, infrared light - 12m;
RT100T: red light -12m; infrared light -20m
Minimum detection object: opaque objects above Φ15mm
Working environment temperature: -25~+70°C
Output: Relay contact: AC250V 5A
MOS relay: I: 100mA V: AC/DC350V
Level output: 24V maximum current 100mA
Response time: OC gate output ≤ 2ms relay ≤ 20ms
Level ≤ 2ms MOS relay ≤ 2ms
Operation mode: when the amount of incident light of the dark motion-receiver is reduced, there is an action output.
When the amount of incident light of the bright-receiver increases, there is an action output
