Affordable Safety Light Curtains & Cost-Effective Safety Curtain Sensors
Content updated:
A lower acquisition price is useful only after the required safety function is satisfied. Compare the light curtain families available for your opening using the same resolution, protective height, stopping-time allowance and controller requirements. Request a complete installed-cost quote covering brackets, cables, safety logic, validation and replacement availability; optical synchronization alone does not establish safety performance.
JER & MK Series: The Ultimate Economic Replacement for Major Brands
If you are looking for an Economic replacement for major brands, our JER and MK series are engineered to deliver stable performance in a compact form factor. These series are specifically designed for Small-scale automation and Packaging machinery where space is at a premium.
Optical Synchronization
Forget complex wiring. The JER and MK series utilize Optical Synchronization, meaning no sync wire is needed between the emitter and receiver. This makes them extraordinarily easy to install and reduces labor costs significantly.
Universal Integration
Match the supplied output circuit, pulse behaviour, connector pinout and mounting dimensions to the existing installation. A bracket or cable adapter does not establish safety-controller compatibility. A hydraulic press retrofit requires its own stopping-performance and safeguarding validation; do not assume every JER or MK configuration is suitable.
Quality You Can Check: Product and System Evidence
Request the exact MK or JER order code, applicable Type/PL/SIL documentation, declaration of conformity and supplied manual. A company ISO certificate or CE logo does not establish a model's protective capability. Do not use an economical variant for a press safety function unless its documented rating, outputs and integration meet the risk assessment. Rockwell's GuardShield documentation illustrates the distinction between a product safety classification and the conditions attached to its certification.



Ideal Applications for JER & MK Series
| Industry / Machine | Benefit of JER/MK Series |
|---|---|
| Small-scale Automation | Space-saving, stable infrared barrier for simple logic. |
| Packaging Machinery | High-speed detection with very low maintenance cost. |
| Hydraulic Press Guarding | Only a documented safety-rated variant and validated press function are suitable. |
