Product Overview
The Z-15GW4-B is used to deliver repeatable machine-state detection for sequencing, interlocks, and process confirmation. Whether in packaging, handling, or assembly systems, this sensing class helps reduce false triggers and improves control confidence under continuous operation.
Repeatable State Detection
Accurate detection at the right process moment improves sequence integrity and reduces quality escapes caused by timing uncertainty or missed events.
Fit for Demanding Machine Environments
Industrial sensing components are selected for stability under vibration, contamination, and repetitive duty where consumer-grade devices are not suitable.
Faster Commissioning and Replacement
Standardized sensor families simplify spare strategy, reduce replacement errors, and support quicker return to production after maintenance events.

FAQ for Z-15GW4-B
When should I use pin plunger vs roller lever?
Pin plunger for: direct pressing applications, limited space where lever won't fit, linear motion detection. Roller lever for: cam operation, rotating mechanisms, reduced friction requirements, continuous cycling.
What's the operating force for pin plunger?
2.94N (300gf) maximum operating force. Ensure your mechanism can provide this force with some margin. For lower force requirements, consider high-sensitivity basic switches.
Can I mount this switch in any orientation?
Yes, pin plunger works in any orientation. For vertical mounting with plunger facing down, ensure mechanism provides positive actuation. For plunger facing up, consider dust cover to prevent contamination.
What's the typical application for pin plunger limit switch?
End-of-travel detection, part presence sensing, door/window position, safety interlock (non-safety rated), manual override detection, and any application requiring direct linear actuation.
