Penta Sensors

The Penta Sensor provides analog voltage outputs, and features built-in color binning, eliminating the need to convert LED wavelength to visual color in the ATE software, and saving
valuable processing time.

・Most popular.
・Simple and easy to use.
・Quick response.
・Can distinguish between 5 standard colors and white.
・If you want to test boundary colors like yellow-green,choose the Spectra Sensor instead.



Sensor Characteristics

Operating temperature range: 0 to 70 degrees celsius
Typical response time: color and intensity outputs
simultaneously in less than 340mS

Power consumption: Approx. 6mA with a 5-volt supply

 Sensors are one of the smallest LED sensors on the market. When paired with Fiber-optic Probes they will test LEDs spaced as close as 0.050(1.27mm) inches on centers.
Output Loads:Intensity & Color 2Kohms min.,100pf,max.



Color Response

Test for the five main LED colors, plus white, and provide an unambiguous and stable analog voltage output, independent of LED intensity, for each color:

Blue: 1.0 volts         Green: 1.5 volts
Yellow/Amber: 2.0 volts  Orange: 2.5 volts
Red: 3.0 volts         White: 3.5 volts



Intensity Response

Analog output ranging from 0 to 4 volts, corresponding to the LED’s luminous intensity in millicandelas (C.I.E. photopic-curve-corrected).
Read-out of less than 50mV indicates under-ranging (LED too dim) and over 4.0 volts indicates over-ranging (LED too bright).
The sensor’s intensity response depends on a variety of factors, including the size of the LED, the aperture of the fiber-optic probe, and the distance of the probe tip from the LED emitter.
For the test of very dim LEDs, High Sensitivity Sensors are available. For the test of very bright LEDs, Penta Low-Sensitivity or Very Low Sensitivity Sensors are available.
Tests LEDS from 1mcd to 20,000mcd (~ 315,000mcd with the Penta Very-Low Sensitivity Sensor.)



Supply Voltage Protection

Sensors offer reliability and versatility, operating at any voltage from +5 volts to +40 volts and withstanding reverse polarity up to -18 volts without permanent damage. This provides immunity from accidental power supply wiring mistakes and from reverse polarity up to -18 volt “spikes” due to D.C. power line inductive switching transients as well as inadvertent reverse polarity “shorts” testers, while permitting their operation from different D.C. supply voltages commonly encountered in industry.

Penta Sensor Pin-Out

Four standard wire-wrap pins are used for:
G – Ground, common 2-level wire-wrap pin for individual analog signal output and power input ground connections
Int. – Intensity of LED under test (relative)
Color – Color of LED under test
P – DC Power input, +5,12,24 or 28 volts


Fiber-optic Probes

Penta Sensors are available with a choice of Fiber-Optic Probes.
Their stainless-steel tips range from 0.050(1.27mm) inches to 0.134(3.40mm) inches in diameter. The popular Trident enables the test of three LEDs for the cost of a single sensor. Fiber-optic probes are available for refined intensity test, for the test of dim LED’s and to compensate for misalignment errors.
Custom fiber-optic cable lengths may be ordered.

Installing the Sensor and Fiber-Optic Probe Units

Installation is achieved with one-hole fixing, using a simple clamp for the sensor and forked clamps for the probes to allow the height of the probes above the LEDs to be
adjusted. Four wire-wrap pins are provided on the sensor for D.C. power and signal connections, or use the Universal LightProbe Connector Cable for easy, error-free wiring to the ATE .
