Introduction to the CDVI STAR-PB Mullion Proximity Reader and Key Features
CDVI STAR-PB Mullion Proximity Readeris a compact, narrow-profile access control reader built for locations where space is limited but performance and reliability cannot be compromised. Using 125 kHz proximity technology, the STAR-PB delivers straightforward credential reading, clear visual and audible feedback, and a robust mechanical design that withstands everyday wear and outdoor exposures. With Wiegand outputs (26 / 30 / 44 bit), low power consumption, and extended operating temperature range, this mullion reader is particularly suited to door frames, uprights, and other narrow mounting surfaces where a conventional reader would be bulky or impractical.
Detailed Description: Specifications and Benefits
The STAR-PB is intentionally minimal in size yet rich in practical features. Its mullion form factor measures approximately H 130 mm × W 41 mm × D 28 mm and weighs about 0.09 kg, allowing discreet installation on door jambs and slim uprights. The reader’s polycarbonate housing combines light weight with impact resistance (IK10) and weather tolerance (IP53), meaning it resists dust ingress and splashing water — practical for external door frames protected from direct heavy rain.
Key electrical and performance specifications include a 12 Vdc supply and a low current draw of around 100 mA, which helps reduce overall power budgets in multi-door installations. Wiring runs are supported up to approximately 150 m, giving installers flexibility when connecting to central controllers. The reader supports typical 125 kHz proximity cards and tags with an open-field read range generally between 5 and 50 mm depending on the credential used. Compatibility with common Wiegand formats (26, 30 and 44 bit) ensures broad integration with many access control systems.
The product is designed for real-world usage: multi-coloured LED indicators provide obvious visual status for valid and invalid reads, and an audible buzzer offers immediate user feedback — particularly useful in noisy or busy entrances. Manufacturer-backed features such as a 10-year warranty from CDVI and a user capacity up to 10,000 (subject to controller compatibility) add commercial confidence for long-term deployments.

The mullion profile is the STAR-PB’s defining advantage: many sites have limited space alongside doors, glass panels, or uprights where a full-sized reader would not fit. The narrow footprint keeps the reader out of the way of hinges and framing, preserves the aesthetic of the entrance, and simplifies retrofitting where surface area is constrained. IP53 and IK10 ratings mean the unit can handle everyday knocks and light outdoor exposure without frequent replacements, reducing total cost of ownership.
125 kHz proximity technology remains widely used because of its simplicity and compatibility with established card/tag inventories. Where organisations already hold 125 kHz credentials, deploying a reader like the STAR-PB avoids the expense of reissuing credentials. Wiegand outputs mean installers can connect to a wide variety of controllers without needing custom interfaces.
Use Cases and Scenarios Where the STAR-PB Excels
The STAR-PB is particularly well suited to several common installation scenarios:
- Door frames and narrow stiles:Its mullion shape is ideal for mounting on door jambs, narrow metal uprights, or the vertical sections of storefronts where a full-width reader would be obtrusive.
- Retrofit projects:In upgrades where existing door furniture or wiring is retained, the STAR-PB’s compact size and Wiegand compatibility make it a simple swap-in replacement or addition.
- Multi-door sites with limited external protection:IP53 rating handles dust and light splashes for covered doorways, and IK10 gives confidence in environments where readers might be subject to accidental impact or vandalism.
- Cost-conscious deployments:For organisations that wish to maintain 125 kHz credentials rather than migrate to higher-frequency smart cards, the STAR-PB provides a reliable, economical reading solution with long-term manufacturer support.
- Commercial offices, retail, light industrial:The reader fits well on employee entrance doors, loading bays with covered door frames, and retail back-of-house doors where space is constrained.
Comparisons with Similar Products on the Market
When evaluating mullion readers, buyers typically weigh form factor, read technology, interface compatibility, environmental resilience, and price. The STAR-PB compares favorably across these dimensions:
- Form factor:Many manufacturers offer mullion readers, but the STAR-PB’s slim dimensions (130 × 41 × 28 mm) and light weight make it easier to integrate into tight spaces compared with bulkier models.
- Technology:The STAR-PB uses 125 kHz proximity. If your site already uses proximity cards, this is an advantage; however, if you plan to move to encrypted smart credentials (13.56 MHz with MIFARE or DESFire), consider higher-frequency readers. The STAR-PB is optimized for legacy credential compatibility rather than smart card migration.
- Interface:Wiegand 26/30/44 is widely supported. Some competing readers provide additional interfaces such as RS485 or OSDP for encrypted communications; where advanced controller-level security is required, you may prefer those interfaces. For many standard access control panels, Wiegand remains the simplest and most compatible option.
- Durability:The combination of IP53 and IK10 is competitive for mullion readers. Some fully weatherproof readers carry IP65 or IP67 ratings for exposed external sites — if you need heavy rain protection or washdown resilience, select an enclosure or a reader with higher ingress protection.
- Price and warranty:With a suggested retail price around 112 (currency dependent) and a 10-year CDVI warranty, the STAR-PB offers solid value. Cheaper generic readers may exist, but often lack manufacturer-backed long warranties and consistent build quality.
Your choice depends on credential strategy, environmental requirements, and controller capabilities. The STAR-PB is an excellent fit for installations prioritising a narrow profile, straightforward 125 kHz compatibility, and a resilient housing backed by a decade-long warranty. If you require contactless smart card support, encrypted controller links, or full weatherproofing for exposed external doors, evaluate readers that target those specific needs.
Customer Feedback and Testimonials
Feedback from installers and users highlights why the STAR-PB is frequently selected for constrained sites. The following quotes reflect common themes reported by integrators and facilities managers:
- Installer — regional security firm:"The STAR-PB’s slim profile made retrofits straightforward; we didn’t need to modify the door frames and the Wiegand output plugged straight into the panel. Robust build and consistent reads have cut call-backs."
- Facilities manager — retail chain:"We needed a reader that didn’t look bulky on our front doors. The multi-coloured LED and buzzer give clear feedback for staff, and the long warranty gives us confidence in the deployment."
- Systems integrator:"For sites still using 125 kHz credentials, the STAR-PB is cost-effective and reliable. It’s a good balance between performance, durability and price."
Note: these testimonials are representative of typical feedback shared by installers and end users. Prospective buyers should consult local references or request trial units to validate real-world performance for their specific credentials and mounting conditions.
Conclusion: Why the STAR-PB Is a Great Choice
The CDVI STAR-PB Mullion Proximity Reader addresses a common challenge in access control: how to provide dependable credential reading in locations where space is at a premium. Its narrow mullion design makes it ideal for door frames and slim uprights, while 125 kHz proximity compatibility and Wiegand outputs ensure broad system integration. Durable materials and protective ratings (IP53, IK10), low power draw, extended operating temperature range, and a 10-year manufacturer warranty make the STAR-PB a practical, long-term choice for commercial and light-industrial installations.
For organisations that already use 125 kHz cards or tags and need a compact, proven reader for retrofits or new installations with limited mounting space, the STAR-PB offers a compelling mix of form, function and value. Evaluate the STAR-PB against your controller compatibility, credential strategy and environmental needs — in many cases, it will deliver the discreet, dependable access control solution you’re seeking.
