Mechanical Limit Detection for Machine Interlock and Feedback
Z-15GQ-B belongs to Omron Z basic switch family and is widely used in machine designs requiring reliable mechanical actuation feedback. Snap-action switches are commonly selected for end-position sensing, gate state confirmation, and mechanism interlock signals where deterministic contact change is required. This model is frequently applied in transfer mechanisms, actuator strokes, and door/cover supervision circuits. During selection, engineers should validate actuator mechanics, expected operating force, overtravel limits, and electrical load category to ensure reliable service life. Proper mounting rigidity and environmental protection strategy are essential in high-vibration or contaminant-prone settings. Z-15GQ-B is typically chosen for its practical integration, maintainable replacement approach, and consistent mechanical signaling behavior across broad industrial use cases.
Typical Applications
- Linear actuator end-of-stroke detection
- Door and guard interlock state sensing
- Cam position signaling in indexing systems
- Transfer mechanism home position feedback
- Auxiliary limit input to PLC sequence logic
- Legacy switch replacement in existing equipment
Buying Checklist
- Verify actuator profile and required operating force in mechanism design.
- Check electrical load type and contact rating margin for driven circuit.
- Assess mounting tolerance and overtravel constraints for long service life.
- Review environmental exposure and protective sealing requirements.
- Plan periodic inspection based on mechanical cycle duty.

Frequently Asked Questions
What's the difference between basic switch and limit switch?
Basic switch (Z-15GQ) has pin plunger actuator for direct pressing. Limit switch (Z-15GW) has lever/roller actuator for cam operation. Choose basic switch for push-button applications, limit switch for mechanical cam/travel detection.
What's the maximum switching frequency?
For resistive loads: up to 1800 operations/hour. For inductive loads (motors, solenoids): reduce to 600 operations/hour. For higher frequency, consider low-current basic switches or proximity sensors.
Can this switch be used for safety interlocks?
No, Z series basic switches are not certified for safety applications. For safety interlocks (guard switches, emergency stops), use D4 series safety switches with direct opening action and safety certifications.
How do I wire the SPDT contacts?
SPDT has 3 terminals: COM (common), NO (normally open), NC (normally closed). In resting state, COM connects to NC. When actuated, COM connects to NO. Use NO for alarm/indication, NC for safety/monitoring circuits.
What applications commonly use this switch?
Door interlocks (non-safety), lid switches, position detection, end-of-travel limits (non-critical), manual override switches, and general purpose industrial switching where 15A capacity is needed.
