2. Main Characteristics:
* Fast response time <20ms.
* LED indicator,easy to algin, display real-time working status.
* Auto self-checking function to avoid output wrong signals to control circuit.
* Dual relay output to guarantee high safety.
* Reset function: When any beam(one or more) is obstructed, equipment can't run till press "Reset" Button, light passing recovers as well.
* Easy connection: End lid with aviation plug in connector and cable.
* High anti-interference: not affected by electromagnetic signal, strobe, welding arc and other periphery light.
Anti-vibration: adoption of several shock-absorbers like rubber washer, damper to reduce vibration by the greatest extent.
1. Main Characteristics:
1. Self-checking function
When the device has the malfunctions happen or suffers from sudden power off, it doesn't send the mistaken signal to equipment protected.
2. Anti-interference
Not affected by periphery lights such as the electromagnetism signal, strobe, welding arc etc.
3. Self-locking function
When the light curtain beam( one or more) is interrupted, controller sends output signal to brake the press's movement at once and the movement can't restart until press the "reset" button, meanwhile light passing as well.
4. High-reliability, Three safety reply output, 3N/O or 2N/O,1N/C output; respond time <=20ms.
5. Obtained the ISO9001-2008 Certificate, CE, CCC certificate and Certified by the International Safety Standard EN61496-1 ESPE (Type 4) and so on.

SC Series Bottom Dead Point Monitoring Device :
SC31/32
This device will detect the slugs coming up by detecting the displacement of stripper plate when slugs come up. The displacement is detected by the sensors, which are installed on the stripper plate.
Detection Method:
Bottom Dead Center Monitoring (B.D.C)
If a slug is caught in the die with spring loaded stripper, the stripper position will be changed,the slug is detected by the displacement of the B.D.C.
1, Characteristic:
The slug, which is caught in upper or lower surface of the raw material will be crashed by stripper plate of the die which has spring loaded stopper at B.D.C. However, 20 to 40% of slug thickness (depends on material) will be remained and it will shift the position of stripper plate. This device will detect the displacement of the stripper plate by comparing with normal position.
This device will not be affected by the change of material thickness or rise in temperature of the unit since it compares the displacement of the stripper plate at every stroke. This device is not be affected by the bound or spring load of the stripper plate due to bottom hold type system which only detects the lowest point of the stripper plate by using micro-processor.
