Detects the presence or absence of materials. Is used for monitoring the speed of machinery via a speed module or PLC.
- Detects the presence of metallic objects in dangerous conditions such as in handling, warehousing, packaging, conveying, assembly, processing, etc.
- May also be used to generate pulses for the detection of rotational speed
- 2-wire multi-voltage technology or 10-30 VDC NPN/PNP
- Detects up to 6mm

Whirligig®
The Whirligig® is a fully guarded target for easy mounting of motion sensors. It is a universal shaft sensor mount suitable for all industry standard cylindrical or DIN style inductive sensors including 4B's M100, M300, and M800 speed switch sensors.
The sensor bolts to the Whirligig base plate and the complete assembly either bolts to the machines shaft through a M12 tapped hole, or is connected magnetically using 4B’s patented Mag-Con™ adaptor. Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft. With the Whirligig, installation of speed sensors is now simple, safe and reliable.
4B Sensor Mounting Kit
The 4B Sensor Mounting Kit is able to securely mount barrel sensors in position, including 4B’s range of 18 & 30mm wide inductive sensors.
Made of Stainless Steel and Nylon 66, giving corrosion resistance as well as abrasion resistance and high melting points, the brackets are ideal for harsh environments.
A flexible mounting head and foot can be rotated independently before being locked in the required position using the supplied screws.
4B Speed Relay (USR)
The Speed Relay is a microprocessor controlled digital speed monitor for use with 2, 3, 4 wire NPN/PNP sensors, 4B’s WDA range of sensors or Contact sensor inputs, with a user programmable electromechanical relay and PhotoMOS Solid State Relay (SSR) outputs. The Speed Relay has a 160x80 pixel LCD display to provide information, and 3 front panel buttons to program settings.
Design Services
Hazard Monitoring Design Service
Hazard Monitoring Design Service
Preventative maintenance can help reduce the risk of equipment failure and consequent downtimes. When it comes to monitoring your bucket elevators and belt conveyors, 4B can recommend you the ideal combination of sensors and monitoring systems to suit your requirements and budget.
4B provides an extensive range of their own ATEX / IECEx / CSA approved hazard monitoring systems, misalignment switches and bearing temperature monitors and level controls. We can offer you anything from a replacement sensor to a fully integrated hazard monitoring system which can be operated either as a stand-alone system or connected to your PLC.
And if you do not want to install hazard monitoring sensors on every piece of equipment in your plant straightaway, we can offer you a scalable solution starting with carefully chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.
We can also offer you an installation service, and we do provide a competent after-sales technical service to help you overcome any technical problems with your monitoring equipment.
To get a recommendation from our engineers, please fill in the electronics questionnaire below. Please fill this form in as accurately as possible to allow us to deal with your enquiry more effectively.
