1. What type of signal does a safety mat detect?
(1) The safety mat provides a passive (dry contact) digital switch signal.
(2) The circuit is open when not stepped on, and closes when stepped on.
(3) It can be directly connected to an intermediate relay or PLC.
(4) Both “dry contact” and “dry switch” refer to digital (on/off) switch signals.
2. Is a safety mat controller mandatory?
No, it is not required. The safety mat itself outputs a passive normally open (NO) signal, which can be directly wired to a PLC or intermediate relay. If your system accepts a simple NO signal, you do not need a dedicated controller.
3. Can I get a normally closed (NC) version of the safety mat?
The safety mat can only be manufactured as normally open (NO). This is because it consists of two conductive layers: when unpressed, the layers are separated; when stepped on, the top layer presses down to contact the bottom layer, completing the circuit.
To achieve a normally closed (NC) function, you can either:
Use our safety mat controller, or
Add an external intermediate relay in your control circuit.
4. I ordered the wrong size—can I cut the safety mat myself?
No, you cannot cut it. The internal pressure-sensitive sensors are wired in series. Cutting will break the sensor circuit, rendering the mat non-functional.
5. What are the installation environment requirements for a safety mat?
The installation surface must be flat and free of sharp objects to prevent puncturing or damaging the mat.
6. What is the actuation force (triggering weight) of the safety mat?
The actuation force is 30 kg—easily triggered by an adult’s footstep.
7. What is the thickness of the safety mat?
Flat areas (without anti-slip dots): 12 mm
Areas with anti-slip raised dots: 14 mm
Edge reinforcement (border): 15 mm
8. What is the cable specification (wire gauge) of the safety mat?
It uses a 4-core cable with each conductor rated at 0.25 mm² (i.e., 4 × 0.25 mm²).
9. What voltage does the safety mat operate at?
The safety mat itself is passive and requires no power supply. It is designed to be connected into a 24V control circuit (typically DC24V).
10. What material is the safety mat made of?
It is made of nitrile rubber (NBR)—durable, oil-resistant, and suitable for industrial environments.
11. What is the response time of the safety mat?
The response time is ≤30 milliseconds (ms).
12. What sizes are available for the safety mat?
Custom sizes and shapes are supported based on your drawings.
Standard stock sizes include: 1000 × 500 mm, 500 × 500 mm, and others.
13. What colors are available?
Two colors: Black and Yellow.
