Magnasphere Corp HS-L1.5-111-C36-L-4 Magnetic Contact Switch

Product Description

The MAGNASPHERE CORP HS-L1.5-111-C36-L-4 is a special application magnetic contact switch supplied as a single unit with a 36-inch cable lead. Magnetic contact switches of this type are used in security, access control, and monitoring circuits to detect the open or closed state of a door, panel, hatch, or enclosure. The switch operates without mechanical contact, relying on magnetic field proximity to change circuit state, which reduces wear and supports long service life in demanding environments. Licensed security and low-voltage electricians are the primary installers for this product type.

This magnetic contact switch is classified under special application contacts, indicating it is intended for installations where standard off-the-shelf reed switches are not adequate. Typical scenarios include industrial enclosures, commercial access panels, equipment cabinets, and security perimeter points requiring a compact, robust magnetic sensing solution. The 36-inch cable provides sufficient lead length for most standard junction box and panel rough-in configurations without requiring an additional pigtail splice at the device.

Key Features

• Special application magnetic contact rated for demanding sensing environments
• 36-inch factory-attached cable lead simplifies rough-in wiring
• Non-contact magnetic operation eliminates mechanical wear on switching surfaces
• Compact form factor suitable for door frames, hatches, and enclosure mounting
• Sold as a single unit for direct one-for-one replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-install solution for special application magnetic contact switch positions in security, access control, and low-voltage monitoring systems.

Installation Notes

Installation of magnetic contact switches is typically performed by licensed low-voltage electricians or security system technicians. De-energize the circuit and discharge any capacitive backup power before terminating leads. Follow NEC Article 725 guidelines for Class 2 and Class 3 low-voltage wiring where applicable. Do not kink or sharply bend the cable lead, and maintain the manufacturer-specified gap between the switch body and magnet actuator to ensure reliable operation.
