Product SKU: WSF42

Product Overview

The SECOR WSF42 Recessed White Reed Switch NC 25mm Diameter 35mm Gap is a flush mount magnetic reed switch designed for compatible alarm, access control and door monitoring applications. It provides a normally closed SPST contact and a wide 35mm operating gap, making it suitable for installations where a recessed reed switch is preferred but additional magnet-to-switch tolerance is required. The white 25mm diameter body provides a clean finish for suitable door frames, commercial openings and protected access points where surface mounted contacts are not preferred. With a maximum resistance of 0.2Ω, 10W maximum rating, 100VDC maximum voltage and 500mA maximum current, the WSF42 is a practical option for low-voltage security circuits requiring discreet recessed open/close monitoring.

Key Capabilities

Recessed Reed Switch

The WSF42 is designed for flush mount installation where a discreet magnetic contact is preferred over a surface mounted reed switch.

Wide 35mm Gap

The listed 35mm gap gives installers extra alignment tolerance compared with smaller recessed contacts.

Normally Closed SPST Contact

The NC SPST contact format suits compatible alarm and access control inputs configured for normally closed monitoring.

25mm Diameter Body

The 25mm diameter body suits compatible door and frame installations where a larger recessed contact can be fitted securely.

White Flush Finish

The white finish helps the contact blend neatly into light-coloured doors, frames and commercial fit-outs.

Low-Voltage Security Circuit Use

The listed ratings suit compatible low-voltage monitoring circuits where voltage, current and load remain within the specified limits.

Best For

Recessed Door Monitoring: Suitable where a discreet flush mount contact is preferred over visible surface mounted hardware.
Wide-Gap Applications: Useful where a 35mm gap is required due to door alignment, frame depth or movement.
Commercial Door Contacts: Practical for compatible alarm and access control systems monitoring commercial doors and protected openings.
Access Control Inputs: Can be used for door status monitoring where the controller supports NC SPST contact operation.
Clean Internal Fit-Offs: A good option where a white recessed contact is required for a neat, low-profile finish.

Why Choose the WSF42

Choose the SECOR WSF42 when the installation needs a recessed white reed switch with a wider 35mm operating gap. Its normally closed SPST contact, 25mm diameter body and 30mm depth make it suitable for compatible alarm and access control circuits where clean recessed monitoring is required. Compared with smaller recessed contacts, the WSF42 provides a larger body and wider listed gap, making it useful where the installer needs additional mounting tolerance. This model, supplied by Security Wholesalers, is a practical choice for professional low-voltage security installations requiring discreet door or protected opening monitoring.

Buyer Decision Tips

Buyer Tip: Confirm the frame can accept a 25mm diameter recessed reed switch before ordering. The WSF42 requires suitable drilling depth, cable access and secure magnet alignment.

Buyer Tip: Confirm the connected alarm or access control input requires an NC SPST contact and that the circuit remains within the listed 100VDC, 500mA and 10W limits.

Choosing the Right Model

Choose this model if: You need a white recessed reed switch with NC SPST contact, 25mm diameter body and 35mm gap.
Choose WSF41 if: You need a smaller 19mm diameter recessed reed switch for steel door applications with a 25mm gap.
Choose WSF43 if: You need a smaller stubby 9.5mm diameter flush mount contact for timber door frames.
Choose a surface mount contact if: The door or frame cannot be drilled for recessed installation.
Choose an armoured contact if: The contact location is exposed, rugged or requires additional cable protection.
Check before installation: Confirm drilling diameter, frame depth, contact type, circuit rating, cable path and magnet alignment.

FAQs

What is the SECOR WSF42 used for?
The SECOR WSF42 is used as a recessed magnetic reed switch for compatible alarm and access control systems. It monitors whether a door, frame or protected opening is open or closed using a hidden flush mounted contact and matching magnet.
What gap does the WSF42 support?
The WSF42 has a listed operating gap of 35mm. This provides more tolerance than many smaller recessed contacts, although final performance still depends on magnet alignment, door movement, frame material and installation accuracy.
Is the WSF42 normally closed?
Yes. The WSF42 uses an NC SPST contact. The installer should confirm the connected alarm panel or access control input is configured for normally closed contact monitoring before installation.
Is this a surface mount reed switch?
No. The WSF42 is a recessed or flush mount reed switch. It is designed to be installed into a suitable drilled opening, giving a cleaner finish than a visible surface mounted contact.
What size hole is required for the WSF42?
The WSF42 has a listed body size of 25mm diameter x 30mm. Installers should confirm the correct drilling size, frame depth, cable route and magnet position before fitting the reed switch.
What are the electrical ratings?
The WSF42 has a maximum resistance of 0.2Ω, maximum rating of 10W, maximum voltage of 100VDC and maximum current of 500mA. The connected circuit should remain within these ratings for safe and reliable operation.
Can the WSF42 be used with access control systems?
Yes. The WSF42 can be used as a door status input on compatible access control systems where the controller supports NC SPST contact monitoring and the circuit remains within the listed electrical ratings.
What should I check before buying the WSF42?
Before buying the WSF42, confirm that your system requires an NC SPST recessed reed switch, the 35mm gap suits the opening, and the frame can accept a 25mm diameter contact. This model is available through Security Wholesalers for compatible alarm and access control monitoring applications.
