The NAMCO Focused Field FlatPak™ Proximity Sensor is a Super Heavy Duty, completely encapsulated sensor designed to sense large metal objects at long ranges in tough environments. It is the first sensor of this body style to offer a focused sensing field.
The focused sensing field allows this sensor to be mounted flush with surrounding metal with only a .25 inch gap between the sensor and the metal surface. This sensor will operate reliably in this setting without adjustment all year round regardless of changes in ambient temperature.
Competitive sensors have traditionally included a trim pot to enable the user to revise the sensing distance when ambient conditions change. These sensors are susceptible to substantial growth in sensing range when ambient temperatures change from season to season. They eventually "lock on" to surrounding metal due to this growth in range and to the unfocused nature of their sensing fields.
The Namco Focused Field FlatPak™ Sensor has two advantages over competitive products that eliminate the need for constant adjustment. In fact, there are no sensitivity adjustments to be made, ever!!!
The first advantage is the focused field. The shape of this field minimizes sensing of surrounding metal. When mounted in an identical setting to the competitive switch, the Focused Field FlatPak's sensing range changes less than 10%, and the shape of the field stays focused forward of the switch.
The second advantage is exceptional stability over temperature. The Namco FlatPak's range will increase a maximum of 10% even at the maximum ambient temperature, and the shape of the field will continue in a non‑side‑sensing focused field.
The Namco Focused Field FlatPak™ proximity sensor requires only a .25 inch clearance to surrounding metal. Once installed with this clearance, the sensor will never lock on to surrounding metal.
This Namco FlatPak also includes the most noise resistant circuitry in the business, Namco's patented Weld Field Immune (WFI) circuitry. Not only will the sensor operate reliably in the presence of 20,000 amp weld fields, it also powers up glitch‑free and is extremely resistant to radio frequency interference and other forms of electrical noise. Problems such as "false detection" and "dropping out" are non‑existent, further minimizing programming and maintenance
requirements.
Namco's WFI circuit includes latching Short Circuit Protection (SCP). If the sensor detects excessive current, it reverts to a sleep state with LEDs flashing. This provides a clear indication of a problem in the circuit, simplifying the troubleshooting task. The sensor draws minimal current (2 mA) and can
remain in this state indefinitely.
The Namco Focused Field FlatPak™ Sensor is designed to directly replace existing sensors of this format. It mounts on 65mm bolt centers and is the only sensor of this type that is Made in the USA. It comes with a Lifetime Free Replacement Warranty.
