MON2 vs RET2: Choosing Your Ideal Universal Photoeye 

Universal photoeye

Achieving the ultimate level of access control relies on a high-quality monitoring method designed to deliver the reliability, flexibility, and performance you require. At EMX, we have designed a wide array of innovative photoeye solutions that provide premium entrapment protection for doors, gates, and barriers. Two solutions include the MON2 and RET2, which are both universal monitoring methods that can be used in monitored and non-monitored applications. UL325 compliant and capable of seamlessly integrating with a wide range of products, these photoeyes offer many advantages but differ from one another in a few key ways, including the way they operate. 

A thru beam photoeye like the MON2 consists of a two-piece unit with a separate transmitter and receiver that are mounted opposite of one another. The transmitter emits an infrared beam that the receiver detects, and the strength of this beam lends to its reliability. Though installation may take more time due to the multiple units, the investment in greater performance and reliability delivers a strong benefit. 

The RET2 is a retroreflective photoeye, combining the transmitter and receiver into a single unit with a separate reflector installed to bounce the infrared beam back to the receiver. It requires fewer cables, streamlines installation, and is ideal for smaller spaces, roadways, and entrances due to the lowered chance of interference. Though it has a smaller operating range than thru beam options, its convenience and flexibility are sought in many applications.
