Product News: Sensors Monitors & Transducers
Steel Proximity Sensors monitor ferrous metal components.
Press Release Summary:
Dec 05, 2003 - With built-in relay contacts, PRX+4000 sensors respond to proximity of ferrous material and report relative position of elements that require continuous monitoring. No power is required for sensors to operate and no physical contact is required for activation. Features include SPST Form A contact arrangement, switching ratings of 120 V, and operating distances of 0.250-0.400 in. Construction resists contaminants, moisture, and vibration.
Original Press Release
New Patented Durable Steel Proximity Sensors Address Safety & Productivity
Press release date: Nov 17, 2003
November 17, 2003, Chickasha, OK (USA) - Hermetic Switch, Inc. announces the introduction of its patented PRX+4000 series of steel proximity sensors. This series provides the market with durable, ready-to-install steel proximity sensors for use in applications where the position of a ferrous metal component or ancillary part must be monitored to ensure operator safety and productivity.
Applications for the heavy duty PRX+4000 sensors include use as safety switches and presence sensors in commercial mowers, agricultural equipment, construction equipment, industrial equipment and manufacturing applications where the position of steel safety levers, mechanical arms, presence platforms, mower-decks, access doors or other steel components must be monitored. These sensors can also be utilized in military and gaming applications, valve positioning/fluid monitoring devices, security systems, material handling, automation, control systems, robotics - and essentially any application which can benefit from the steel sensing capabilities provided by these novel sensors.
These sensors can sense and switch high energy loads because the relay contacts are built in. In use, each sensor responds to the proximity of ferrous material and reports the relative position of specific application elements that require continuous monitoring. This helps to ensure safe and productive operation of the equipment.
Unlike mechanical, lever-arm sensors, the PRX+4000 series is designed to perform in the most demanding environments. Their rugged construction enables these steel sensors to be used effectively with applications that come in contact with dirt, dust, grass, pesticides, gasoline, grease, lubricants, transmission fluid, grime, moisture, rough terrain and vibration. Two of the sensor models in the PRX+4000 series can be mounted directly to ferrous surfaces.
No power is required for these sensors to operate and no physical contact of any kind is required for sensor activation. In fact, the PRX+4000 sensors can detect steel through nonferrous materials such as plastic, wood, brass and non-magnetic stainless steel - a feature which enhances their versatility and utility.
Specifications for this line of steel sensors include SPST Form A (B & C available) Contact Arrangement, Switching Ratings of 120 Volts (DC/AC max) and Operating Temperature Range of -40°C to +100°C. Other technical specs for the PRX steel sensor vary with specific model but encompass: Switching Ratings of .25 amps to 3 amps (DC/AC max) and 10 watts to 200 watts (DC/AC max); Operating Distances of 0.250 to 0.400 inches; Release Distances of 0.310 to 0.675 inches and Wire Gauges of 16 AWG to 20 AWG. All steel sensor models are available with custom housings, wires and connectors to meet application-specific requirements.
The three models in this patented series are the PRX+4800 (largest and most robust with steel housing), the PRX+4400 (medium size and extremely tough with steel housing) and the PRX+4100 (smallest but very durable with high impact ABS housing).
For customizing options or other information please contact Hermetic Switch at (405) 224-4046 or your local sales representative. Pricing on these sensors depends on model type but generally ranges from $5.00 to $15.00 each for order quantities of 1000 units.
