ESPE safety door switches are used on fences of potentially dangerous machines and areas to monitor opening and closing of doors to ensure people safety protection.
Safety door switch is a kind of safety device, specialized for monitoring open/ close of protective mechanism (like safety fence door, protective cover).
SSR22 series safety door switch with RFID technology to ensure high safety and confidentiality.
The sensor & label support universal coding and unique coding.
Small size is better for mounting.



Model :
 

• SSR22 series 

 
 

---

Features :
 

• Self-diagnose and cross-diagnose design: periodic mutual diagnose improve the safety level;
• Independent and redundant output: In case any risk caused by single loop failure;
• Magnetic holding force can reach 15N, which can replace the door magnet.
