Product Overview
Keyence PR-MB30CP Miniature Photoelectric Sensor – Unused, New Old Stock
The Keyence PR-MB30CP is a compact, stainless-steel background-suppression photoelectric sensor designed for short-range detection tasks where space is limited and reliability is non-negotiable.
Within the PR-M/F series, this model carries the family’s signature traits: stable detection without constant adjustment, strong immunity to ambient light, and rugged construction for chemically demanding environments.
Product Condition
Unused, new old stock in the manufacturer’s packaging. Kept in original packaging with minor signs of handling from storage only.
Product Overview
The PR-MB30CP is a “mini-slim reflective” background-suppression sensor with a working range typically around 1 to 30 mm, enabling precise foreground detection while rejecting distant reflections. Its stainless-steel SUS316L housing is resin-filled for impact resistance and protection against oils, alkaline detergents, and washdown conditions. The series carries high ingress ratings such as IP67 and IP69K, plus NEMA washdown compliance when installed within specification.
An M8 connector simplifies replacement and wiring. The PR-M/F electronics operate on 10–30 VDC with either NPN or PNP output variants, include overcurrent and reverse-polarity protection, and use high-frequency light emission with automatic power control to minimize cross-talk when multiple sensors are mounted close together.
Key Features
- Miniature stainless-steel SUS316L housing, resin-filled for durability
- Background suppression for reliable foreground detection while rejecting distant reflections
- Typical sensing window in the close-range domain (approx. 1–30 mm)
- M8 connector interface for fast changeout and standardized wiring
- High ingress protection (IP67/IP69K series ratings and NEMA washdown compliance)
- 10–30 VDC operation with NPN or PNP open-collector output options
- Integrated reverse-polarity, surge, and overcurrent protection
- Ambient-light immunity through high-frequency emission and cross-talk prevention
- LED indicators for output and stability status during setup and troubleshooting
Applications
- Presence/absence detection of small parts in assembly fixtures
- PCB, substrate, or electronics-handling equipment with limited mounting space
- Packaging lines requiring repeatable detection despite reflective backgrounds
- Food and beverage machinery where washdown resistance is essential
- Conveyor pick-stations or part-transfer verification
- Short-range gauging or position checking in automated machinery
Frequently Asked Questions
Does this sensor provide true background suppression?
Yes. It detects objects within its foreground window while rejecting reflections from more distant surfaces, reducing false triggers.
What output type does the PR-MB30CP use?
The PR-M/F family offers both NPN and PNP open-collector outputs. Buyers should verify the exact variant and wiring requirements in the Keyence documentation for their installation.
Is the housing suitable for washdown areas?
The stainless-steel SUS316L body and resin fill support IP67/IP69K-class protection. Users must still confirm temperature and chemical compatibility for their application.
Does the sensor resist cross-talk when multiple units are mounted together?
Yes. The series employs high-frequency light emission and built-in cross-talk suppression to support dense mounting.
Where can I find precise sensing curves or response times?
Exact performance values are model-specific and published in Keyence’s official datasheet. These should be consulted for engineering sign-off or system validation.
The PR-MB30CP embodies the PR-M/F series’ quiet reputation for durability in tight spaces and tough conditions. Once installed, it becomes one of those components that simply keeps the line moving—ready for its next task in your machine.
