Cornell 4560-017 Surface-Mount Magnetic Door Contact

Description:

Cornell 4560-017 Surface-Mount Magnetic Door Contact consists of two components: The Contact, consisting of a Reed Switch and screw terminals concealed within a small housing. This component mounts to the Door Frame with Field Wiring being terminated to it. Most of the Field Wiring is usually concealed within the Frame and Jamb of the door. The internal Reed Switch is actuated when it is in the presence of the magnet’s field. The Magnet, which mounts to the door, nearly touching the Contact when the door is closed. Magnetic Contacts are highly reliable, long-life devices – mainly because the reed switches are encapsulated inside small glass tubes filled with inert gas, minimizing corrosion of the contacts within. Magnetic Contacts are usually more secure than Rollerball / Plunger Types – because as soon as the door is opened by a few inches, the Magnet and Contact become sufficiently separated to Actuate.

Cornell 4560-017 Features:

• Two-Component Design: Includes a reed switch contact and a magnet, both crucial for operation. The reed switch is housed in a compact, surface-mounted housing on the door frame.

• Magnetic Actuation: The reed switch is activated when in close proximity to the magnet's field. Once the door opens, the separation between the contact and the magnet triggers the system.

• Durable and Reliable: Magnetic contacts are known for their long-lasting performance due to the reed switches being sealed in small glass tubes filled with inert gas, minimizing the risk of corrosion and wear over time.

• Concealed Wiring: Most of the wiring is concealed within the door frame and jamb, giving a clean, tidy installation with minimal visible wiring.

• Mounting Flexibility: The contact is mounted to the door frame, while the magnet is mounted on the door itself, providing versatility in installation for different door configurations.

• Enhanced Security: Magnetic contacts are generally more secure than rollerball or plunger types because even a small door movement will cause the reed switch and magnet to separate and trigger the contact.

Benefits:

• Long Lifespan: The sealed reed switch inside the glass tube ensures high durability, reducing the need for maintenance and providing a long operational life.

• Discreet Installation: Most of the field wiring is concealed within the door frame, creating a clean and aesthetically pleasing installation.

• Increased Security: Magnetic contacts offer a higher level of security compared to other door contact types, as even a slight movement of the door causes the system to activate.

• Reliability: Magnetic contacts are widely regarded for their dependability, as they offer precise activation and long-term performance without significant wear and tear.

• Versatile Application: Suitable for a wide range of doors and door types, making it an adaptable solution for both residential and commercial applications.

Specifications:

• Contact Type: Reed switch enclosed in a small housing.

• Mounting Location: The contact is mounted on the door frame, while the magnet mounts on the door.

• Activation Method: The reed switch is actuated by the presence of the magnet's field; it is triggered when the magnet and reed switch separate upon door movement.

• Wiring: Field wiring is terminated to the contact, with most wiring concealed within the door frame and jamb.

• Durability: The reed switches are encapsulated in glass tubes filled with inert gas to prevent corrosion and wear.

• Security: More secure than rollerball/plunger types, as it activates when the door moves even slightly.

• Operating Environment: Suitable for indoor applications with standard conditions.
