Diffuse reflective sensor with built-in amplifier
The Keyence PZ-G41N is a diffuse reflective photoelectric sensor that integrates its amplifier in a rectangular housing. It operates on 10 to 30 VDC and provides an NPN open-collector output rated at 30 V and 100 mA maximum. A 2 m cable is fitted as standard.
Suitable applications and limitations
This sensor suits automation tasks that need a 1 m detection range on a 30 x 30 cm white target and an IP67 or IP69K enclosure for wet or dusty environments. It is not for applications requiring longer range, background suppression, or a PNP output type.
Key specification for selection
The detecting distance of 1 m on the specified white paper target is the single figure that confirms whether the PZ-G41N will reach the required sensing point in your machine layout.

Questions about this item
What voltage range does the 10-30 VDC supply actually support including ripple?
The sensor operates from 10 to 30 VDC including a ±10% peak-to-peak ripple, and it requires a Class 2 power source with current consumption of 34 mA maximum.
What mounting clearance does the rectangular housing with 2 m cable need?
The rectangular body measures 30 x 30 cm detection area at 1 m range; the fixed 2 m cable exits the housing, so allow bend radius and strain relief at the mounting point.
How do I set LIGHT-ON or DARK-ON mode and adjust sensitivity without miswiring?
Use the switch on the amplifier to select LIGHT-ON or DARK-ON, then turn the 1-turn 230° trimmer while watching the orange output LED and green stable LED; verify polarity before powering because reversed polarity protection is built in.
