Installation
DPB Series Installation
The DPB Series uses a top and bottom bracket mounting configuration. The emitter and receiver are fixed to the machine frame through the mounting brackets at both ends of the housing.
The DPB Series uses a single mounting configuration: the emitter and receiver are secured by the top and bottom mounting brackets at both ends of the aluminum alloy housing.
Each unit is fixed with the standard bracket set — M4 screws, nuts, washers and spring washers — so the sensor pair can be mounted directly onto compact machines and space-constrained automation equipment.
-
Mounting Position Top and bottom ends of the emitter and receiver housing.
-
Bracket Set Standard top and bottom mounting brackets with M4 screws, nuts, washers and spring washers.
-
Alignment The emitter and receiver must be mounted parallel with the optical axes facing each other, so the beams stay aligned across the detection distance.
-
Installation Space The 14.5 × 28 mm front ultra-thin housing allows mounting where installation space is limited.
Wiring Principle
DPB Series Wiring Principle
The DPB Series supports both NPN and PNP output wiring configurations. Select the wiring method according to the output type of the selected model.
NPN Output Wiring
The NPN output switches the signal line to 0 V (GND) when the optical beam is interrupted. Connect the receiver output to the PLC or controller input configured for NPN (sinking) input. Connect the emitter and receiver to DC24V according to the wiring diagram below.
PNP Output Wiring
The PNP output switches the signal line to +24 V when the optical beam is interrupted. Connect the receiver output to the PLC or controller input configured for PNP (sourcing) input. Connect the emitter and receiver to DC24V according to the wiring diagram below.
The actual wiring should follow the wiring diagram provided for the selected DPB model.
Accessories
DPB Series Accessories & Mounting Brackets
The DPB Series includes the emitter and receiver as the main sensing components. Connection cables and mounting accessories are used for installation and system connection.
Emitter & Receiver Set
