According to Seco-Larm, the four new gate/fence beam sensors were tested by ETL against the UL 325-2016 standard. ETL is one of a handful of Nationally Recognized Testing Laboratories, or NRTLs, which provide full test services to ensure electrical products meet tough UL standards.

The four new Seco-Larm gate/fence beam sensors include the E-931-S45RRGQ, a retro-reflective photoelectric beam sensor with a range of up to 45 feet (14 metres), weatherproof construction, adjustable sensing range, a Form “C” relay output, and a normally closed (N.C.) monitored output with a 10k-Ohm resistor.

The E-931-S50RRGQ is a reflective photoelectric beam sensor with a range of up to 50 feet (15 metres), weatherproof construction, a dual-colour LED alignment system, a Form “C” relay output, and a normally closed (N.C.) monitored output with a 10k-Ohm resistor.

The E-931-S33PRGQ is designed as a polarised reflective photoelectric beam sensor that is immune to shiny objects, with a sensing range of up to 33 feet (10 metres), weatherproof construction, a Form “C” relay output, and a normally closed (N.C.) monitored output with a 10k-Ohm resistor.

And finally, the E-960-D90GQ, a twin photobeam detector with a sensing range of up to 90 feet (30 metres), weatherproof construction, a Form “C” relay output, and a normally closed (N.C.) monitored output with a 10k-Ohm resistor.

Seco-Larm is also offering non-UL 325-2016 versions of these sensors.
