Light Curtains
Industrial door light curtains provide reliable, non-contact obstruction detection for commercial and industrial overhead doors. Using photoelectric thru-beam technology, these safety devices create an extended detection field across the door opening, helping protect personnel, vehicles, and equipment during operation.
Designed for demanding industrial environments, light curtains offer accurate detection, straightforward installation, and dependable performance in high-traffic applications. Their multi-beam design provides broader protection than traditional single-beam photo eyes, helping reduce the risk of collisions and equipment damage.
Features & Benefits:
Reliable Obstruction Detection: Multi-beam thru-beam technology detects objects across the door opening for enhanced protection.
Extended Detection Range: Provides an operating range of up to 32 feet for larger commercial and industrial openings.
Easy Installation & Diagnostics: Integrated LED indicators simplify alignment, setup, and troubleshooting.
UL 325 Compliance: Designed to meet applicable UL 325 requirements for monitored entrapment protection when installed in compatible systems.
Non-Contact Protection: Detects obstructions without physical contact, helping prevent damage to vehicles, equipment, and door systems.
Monitored Light Curtain
An invisible blanket of protection
Made of a series of thru-beam photo eyes
This light curtain features continuous monitoring of the door operator's presence and functionality. Upon detecting an obstruction, the system initiates reversal of the door's operation, ensuring a safety-first approach.
Used to extend vertical protection where standard photo eyes provide low coverage.
Light curtains are a good choice for detecting smaller objects and machinery that may be missed by standard photo eyes.
Operating range: 8-32 ft. (2-10m)
Power source: 12-24 volts DC
Housing: ABS plastic with epoxy PVC over aluminum (MLC-K36) or PVC over aluminum (MLC-K72)
Degree of protection: IP67 - sealed against water and dust
Models we offer:
MLC-K36: 3 ft., 8 elements
MLC-K72: 6 ft., 16 elements
Relay Light Curtain
An invisible blanket of protection
Fail-safe with multiple thru-beam photo eyes
Ideal for pre-2020 installations as a secondary safety device where monitored solutions are not required.
