Safescan Laser Safety Sensor Wiring and Power Guide for Automatic Swing Doors
When integrating a Safescan Laser Safety Sensor with an automatic swing door system, installers and OEM partners often ask important technical questions, such as:
- What is the correct voltage requirement for the sensor?
- Can it operate with DC and AC power supplies?
- Does the sensor support PLC control systems or dry contact signal integration?
As a professional OEM manufacturer of automatic door sensors, we understand how crucial it is to ensure compatibility, safety, and reliability. In this article, we’ll answer these questions in detail and provide guidance for correct installation and usage.
1. Power Supply Requirements: Is It 24V DC or AC?
The Safescan Laser Safety Sensor is designed to be highly adaptable and safe for use in commercial and industrial environments. Its power specifications are as follows:
Operating Voltage:
12–36V DC / 12–24V AC (50/60Hz)
This wide input range offers excellent flexibility for integration with:
- Low-voltage DC controllers (commonly used in modern door automation systems)
- Traditional AC control panels
- Battery-powered or backup-powered swing door setups
Important Note: For optimal performance and safety compliance, we recommend using a regulated 24V DC power supply.
2. Wiring Interface: How to Connect the Safescan Sensor?
The Safescan series sensors include clearly labeled terminals to simplify installation. A typical wiring interface includes:
- Power Input Terminals: For connecting DC/AC voltage
- Output Terminals: Typically NO (Normally Open) or NC (Normally Closed) dry contact outputs
- Signal Ground and Relay Outputs: For integrating with logic circuits or external safety controls
We provide detailed wiring diagrams in our product manual and offer technical support for your project-specific configurations.
3. Does It Support PLC or Dry Contact Integration?
Yes. The Safescan Laser Safety Sensor fully supports dry contact (relay-based) signal outputs, which makes it highly compatible with:
PLC (Programmable Logic Controller) Systems
- Output signals can be easily read by most industrial PLCs
- Integration via NO/NC relay outputs or optional PNP/NPN transistor outputs
- Reliable for safety zone detection, door activation logic, and human presence sensing
Dry Contact Control Panels
- Compatible with most door controllers, access control systems, and interlocks
- Enables fail-safe triggering without the need for complex programming
- No external power signal needed on the output side—ideal for legacy systems
Pro Tip: If you’re using a PLC, make sure your input ports can detect the relay state (often 24V logic level). We offer wiring kits and interface modules if required.
