How to Choose the Right Centrally Supplied Lock

When evaluating centrally supplied locks for your project, consider these key decision factors:

1. Drive Mechanism: Motor vs. Solenoid

• Motor locks (KR-S1113B): quieter operation, higher tensile strength, better for premium environments

• Solenoid locks (KR-S99S): faster response, simpler mechanism, excellent for high-cycle applications

2. Required Features

• Do users need USB device charging? → KR-S1113B

• Is push-to-open convenience a priority? → KR-S99S

3. Scale of Installation

• Under 50 lockers: consider KERONG's battery-powered range with wireless management

• 50–500+ lockers: centrally supplied is the clear choice for operational efficiency

4. Integration Requirements

• Need TCP/IP integration with existing systems? → All KERONG CU units support this

• Need RS485 for legacy infrastructure? → Supported across the range

• Need OEM/ODM customization? → KERONG's full manufacturing capability is available

5. Environmental Conditions

• Wet areas (pool-side, spa)? → Specify IP-rated locks

• Extreme temperature environments? → KR-S1113B operates from -20°C to +65°C

Whether you're a locker manufacturer embedding our locks into your product, a system integrator designing a smart locker deployment, or a facility operator specifying hardware for a new build — KERONG has the centrally supplied lock solution you need.
