CT4 safety light grid

Product introduction: TÜV-certified safety light curtain products with a safety level of Type 4 / EN / IEC 61496-1-2, Cat. 4 PL e / EN ISO 13849-1-2. The CT4 type safety grating can effectively detect any opaque objects that enter the detection area of the grating and exceed the detection accuracy. It is suitable for safety protection of mechanical presses, hydraulic presses, shears, bending machines and other dangerous places.

product composition

The CT4 safety light curtain system consists of a transmitter, a receiver and two transmission lines. The system works with DC24V, provides two PNP outputs, external equipment monitoring (EDM) function and one auxiliary output (non-safety), and is equipped with a status indication function. There are two types of detection distances: 8m and 15m. The detection accuracy is 14mm, 30mm and 46mm. The detection height is 232 mm to 1672 mm, and the extended accuracy is 120mm.

Typical wiring diagram

CT4 safety light grid using EDM function wiring diagram
Wiring diagram using EDM function (Note: K1, K2: relays or other equipment controlling dangerous parts of the machine; K3: load or PLC (for monitoring). When K3 is not used, the CT4 encoder can work normally.)
CT4 safety light grid does not use EDM function wiring diagram
Wiring diagram without EDM function (Note: When EDM function is not used, EDM and AUX signals need to be shorted. K1, K2: relays or other equipment controlling dangerous parts of the machine; K3: load or PLC (for monitoring). When using K3, the CT4 grating can work normally.)
