The product detect interface offers NPN or PNP standard wiring. Different
types of product detect sensors (optical, magnetic, etc.) can be connected
to this input. A shaft encoder may be connected here.
Connector Type:
• IEC 60130-9 Type 08 way female
Mating Cable Connector (IP67 Types):
• Lumberg: 033208-1
Pin description
• Pin 1 +24VF - 24V floating, max 120mA
• Pin 2 GNDF - Floating Ground
• Pin 3 PD+ - Product Detect positive input
• Pin 4 PD- - Product Detect negative input
• Pin 5 CHA+ - Encoder Channel A positive input
• Pin 6 CHA- - Encoder Channel A negative input
• Pin 7 CHB+ - Encoder Channel B positive input
• Pin 8 CHB- - Encoder Channel B negative input
All input circuits contain opto couplers.
The input range is 10-30V, (NPN, PNP, RS422 differential) at an input
impedance of 2 kOhm.
The maximum pulse frequency of CHA and CHB is 120 kHz
The minimum pulse length of the PD input is 10 micro seconds.
The maximum current for X3, X6, X7 and X21 (optional user port) is 0.5A. In
case of an over-current an automatic resettable fuse protects the system.
The Shaft Encoder input is directly connected in parallel with the
Product Detect Interface. For this reason the electrical specification is
identical as well.
For the same reason, the standard encoder cable has no “Z” connection in
order not to get signal collision with the product detector. If needed e.g. in
labeller applications, the isolated leads may be soldered to the scheduled
pins, or a fully connected cable (Z- version) may be ordered.
Three different types of shaft encoders can be connected:
• NPN-types,
• PNP-types
• Differential types.
