The 1L-MSM-114OH Shutter Contact Reed Switch offered by 1 LEAP Technologies is actually designed for the purposes of monitoring an overhead shutter or door. This product is designed for those applications where the gap of operation needs to be larger and where the system needs to be robust enough for an overhead mounting setup.
The product contains the category of the overhead mount magnetic switch and is exclusively meant for being used in structural and mechanical purposes. This product is not to be used in consumer electronics and/or portable devices like laptops and/or portable devices.
Key features
- Wide Contact Switch for Overhead Shutters
- 3″ Long 2 Core 22 AWG PVC Cable
- Screw Mounting
- Operate Gap 2″ (50mm)
- Switch Mounted on Z Bracket For Convenient Mounting
Broad Contact Switch for Overhead Shutters
The 1L-MSM-114OH has a wide-contact shutter contact reed switch, so this product is very suitable for use in overhead shutters and doors. Since the switch has wide-contact features, the product will not malfunction even when there are slight variations in alignment, especially for overhead shutters and doors.
It is an Overhead Mount Magnetic Switch and is meant for mounting above the shutters/moving panels. In the overhead mounting design, the shutter open and close positions can be efficiently detected.
Switch with Z Bracket for Easy Installation
The switch has a pre-attached Z bracket which makes installation fast, secure, and convenient. The Z bracket ensures that the operating gaps are properly set while installing the switch, which makes it ideal for installing industrial doors, rolling shutters, and automation systems.
3″ long 2 core 22 AWG PVC Cable
Coming with a 2-core 22 AWG PVC-insulated cable measuring 3 inches in length, this magnetic switch provides good connectivity as well as durability to the electrical system. The cable is easily compatible with the control panel, alarms, and automation system.
Screw Mounting for Secured Installation
The screw mounting system enables the fixation of the switch and magnet on metal or non-metallic surfaces. This increases stability and helps avoid misalignment when the overhead shutters function continuously.
Operating Gap Minimum 2″ (50 mm)
The 1L-MSM-114OH has a minimum operational gap of 2 inches or 50 mm, making it suited for applications that require a long sensing range. This is quite advantageous, for instance, with overhead shutter systems where it is not always practical to achieve direct close proximity.
Electrical Configuration and Cabling
It comes along with an overhead switch that has a 3-inch length and 2-core 22 AWG PVC-insulated cable that guarantees a safe and reliable power connection. The insulation on the cable is designed to withstand industrial use and is easily connected to control panels, automation systems, and alarms. It is an optimum length designed specifically for overhead installation.
Mounting Method and Installation
The 1L-MSM-114OH is screw mountable, so the switch and magnet can be mounted firmly on overhead shutters, frames, or structure surfaces. As a result, screw mounting provides a long-lasting mechanism against shutter openings through frequent operation. The integrated Z bracket mount provides easy alignment and flexibility during installation. This facilitates the locking of the desired sensing distance.
Operating Characteristics
This device works with an operational gap of no less than 2 inches (50 mm) and is very ideal for overhead shutters, where the proximity between the switch and magnet may not be feasible. The device is also ideal for detecting the open or closed position of the shutters, where the shutters might be large or moving.
The mechanism of the wide-contact switch provides improved stability in operation and prevents false actuations, allowing for precise positioning sensing.
Design and Construction
The 1L-MSM-114OH has a wide contact switch, which can function effectively even under conditions of overhead shutters, especially when there may be variations in positioning and even some mechanical actions. The Z-type mounting bracket makes it convenient for installing, along with maintaining correct positioning even when operating.
The housing is designed to withstand repetitive operation of the shutters as well as installation stress. The entire design is intended to provide reliable operation in an industrial setup.
Application Areas
The 1L-MSM-114OH Overhead Mount Magnetic Switch has solely been used in instances where the size, mounting, and switch gap of the product have proven to be useful in the application. Some of the uses of the
- Overhead rolling shut
- Industrial and commercial shutter doors
- Warehouse and factory shutter systems
- Automated overhead door systems
- Security and monitoring systems for shutter position detection
- Industrial door access control systems
It is not designed for compact electronic devices or miniature devices.
