Product SKU: WSS60BK
Product Overview
The SECOR WSS60BK Surface Mount Reed Switch Black NC 50mm Gap is a wide-gap magnetic reed switch designed for compatible alarm, access control and door monitoring applications. It features an epoxy-sealed reed switch, normally closed SPST contact and a 50mm operating gap, making it suitable for installations where a wider magnet-to-switch tolerance is required. The black surface mount housing measures 90 x 13 x 18mm and provides a discreet finish for dark doors, black frames, commercial fit-outs, cupboards, cabinets and protected openings where recessed installation is not practical. With a maximum resistance of 0.2Ω, 8W rating, 100VDC maximum voltage and 500mA maximum current, the WSS60BK is a practical option for low-voltage security circuits requiring reliable open/close monitoring.
Key Capabilities
Wide 50mm Gap
The WSS60BK supports a 50mm gap, making it suitable where standard close-gap reed switches may not provide enough mounting tolerance.
Normally Closed Contact
The NC SPST contact format suits compatible alarm and access control inputs configured for normally closed open/close monitoring.
Epoxy-Sealed Reed Switch
The reed switch is epoxy sealed, helping protect the switch element within the surface mount housing.
Surface Mount Installation
The surface mount design is useful for doors, frames, cabinets and openings where recessed reed switch installation is not suitable.
Black Housing Finish
The black housing provides a more discreet finish on dark frames, black doors, commercial joinery and modern interior surfaces.
Low-Voltage Security Circuit Use
The switch ratings suit compatible low-voltage monitoring circuits where the voltage, current and load remain within the listed limits.
Best For
- Door Monitoring: Suitable for compatible alarm systems that need surface-mounted open/close detection on doors or frames.
- Wide-Gap Applications: Useful where a 50mm gap is required due to door alignment, frame depth or mounting position.
- Access Control Inputs: Practical for door position monitoring on compatible access control systems.
- Cabinet and Cupboard Monitoring: Suitable for protected cupboards, cabinets or service enclosures where surface mounting is preferred.
- Dark Frame Installations: A better colour match for black doors, dark frames, commercial interiors and modern fit-outs.
Why Choose the WSS60BK
Choose the SECOR WSS60BK when the installation needs a black surface mount reed switch with a wider 50mm operating gap. Its normally closed SPST contact, epoxy-sealed reed switch and compact 90 x 13 x 18mm housing make it suitable for compatible alarm and access control circuits where reliable open/close monitoring is required. Compared with a standard close-gap contact, the WSS60BK gives installers more tolerance for wider door gaps, uneven mounting surfaces or retrofit applications. This model, supplied by Security Wholesalers, is a practical option for residential and commercial security installations requiring a wide-gap black surface mount reed switch.
Buyer Decision Tips
Buyer Tip: Confirm the required contact type before ordering. The WSS60BK is a normally closed SPST reed switch, so it should match the alarm panel or access control input configuration.
Buyer Tip: Choose the housing colour to suit the installation surface. The WSS60BK is black, while white or beige versions may be more suitable for lighter doors, frames or cabinetry.

Ideal Use Cases
Door Position Monitoring
Use on compatible alarm or access control systems where a door open/closed condition needs to be monitored.
Wide Door Gaps
Suitable where standard reed switches may not suit the gap between the moving door and fixed frame.
Surface Mount Retrofits
Useful for retrofit jobs where recessed contact drilling is not preferred or not practical.
Access-Controlled Doors
Can be used as a door status input for compatible access control systems requiring NC contact monitoring.
Cabinets and Enclosures
A practical contact for monitoring cupboards, storage cabinets or service enclosures in compatible security systems.
Dark Colour Installations
Useful where a black contact provides a better visual match than a white or beige reed switch.
Choosing the Right Model
- Choose this model if: You need a black wide-gap surface mount reed switch with NC SPST contact and 50mm gap.
- Choose WSS60WH if: The installation requires a white housing rather than black.
- Choose WSS60BE if: The installation requires a beige housing for neutral, cream or timber-look surfaces.
- Choose a recessed reed switch if: The project requires hidden installation inside the door and frame rather than surface mounting.
- Choose a standard-gap reed switch if: The door and frame are closely aligned and do not require a 50mm operating gap.
- Check before installation: Confirm gap, contact type, voltage, current, circuit rating, mounting position and magnet alignment.
FAQs
- What is the SECOR WSS60BK used for?
The SECOR WSS60BK is used as a surface mount reed switch for compatible alarm and access control systems. It monitors the open or closed state of doors, frames, cabinets or protected openings using a magnetic reed switch and matching magnet. - What does a 50mm gap mean?
The 50mm gap refers to the listed operating distance between the reed switch and magnet. This wider gap is useful where the door and frame are not close enough for a standard contact, although final performance depends on alignment and mounting conditions. - Is the WSS60BK normally closed?
Yes. The WSS60BK uses an NC SPST contact. The installer should confirm the alarm panel or access control input is configured for normally closed contact monitoring before connecting the reed switch. - Can this reed switch be used on access control doors?
Yes. The WSS60BK can be used for compatible access control door status monitoring where the controller input supports NC contact operation and the voltage and current remain within the listed reed switch ratings. - Is this a recessed reed switch?
No. The WSS60BK is a surface mount reed switch. It is mounted onto the door, frame or monitored surface, making it useful for retrofit installations or areas where recessed drilling is not suitable. - What are the electrical ratings?
The WSS60BK has a maximum resistance of 0.2Ω, maximum rating of 8W, maximum voltage of 100VDC and maximum current of 500mA. The connected circuit should remain within these ratings for safe and reliable operation. - What are the dimensions?
The SECOR WSS60BK measures 90 x 13 x 18mm. Installers should confirm the available mounting space, door/frame clearance and cable route before installation, especially on narrow frames or uneven surfaces. - What should I check before buying the WSS60BK?
Before buying the WSS60BK, confirm that your system requires an NC SPST surface mount reed switch, the 50mm gap suits the door or opening, and the black colour matches the installation surface. This model is available through Security Wholesalers for compatible alarm and access control monitoring applications.
