Magnasphere HS-L1.5-111-800 Magnetic Sensor with Leads, Normally Closed, SPST

Designed for dependable conduit-mounted perimeter and access monitoring, the Magnasphere HS-L1.5-111-800 magnetic sensor delivers rugged, code-compliant protection for security and surveillance systems. This conduit adapter-style magnetic sensor is UL-634 Level 1 rated for high-reliability applications and features two closed-loop normally closed (N.C.) contacts that provide redundancy for alarm and monitoring circuits. An integrated pry-tamper closed loop helps prevent unauthorized access and reduces nuisance alarms at entry points or equipment enclosures.

The HS-L1.5-111-800 is a SPST normally closed device with leads that simplify wiring to alarm panels, access control systems, and intrusion detection networks. With no resistors included, installers have the flexibility to configure end-of-line resistor values to match panel requirements. Built specifically for security professionals, this Magnasphere magnetic sensor is ideal for conduit-mounted doors, enclosures, and perimeter installations where reliable tamper detection and continuous monitoring are essential. Add this sensor to your next installation to improve system integrity and minimize false alarms.
