For testing of SHT2x sensors sockets, such as from

Plastronics,

part

10LQ50S13030

are

recommended (see e.g. www.locknest.com).

Traceability Information

All SHT2x are laser marked with an alphanumeric, five-

digit code on the sensor – see Figure 12.

Figure 12 Laser marking on sensor. For details see text.

The marking on the sensor consists of two lines with five

digits each. The first line denotes the sensor type

(SHT20). The first digit of the second line defines the

output mode (D = digital, Sensibus and I2C, P = PWM, S =

SDM). The second digit defines the manufacturing year (0

= 2010, 1 = 2011, etc.). The last three digits represent an

alphanumeric tracking code. That code can be decoded by

Sensirion only and allows for tracking on batch level

through production, calibration and testing – and will be

provided upon justified request.

Reels are also labeled, as displayed in Figure 13 and

Figure 14, and give additional traceability information.

Figure 13: First label on reel: XX = Sensor Type (20 for SHT20),

O = Output mode (D = Digital, P = PWM, S = SDM), NN =

product revision no., Y = last digit of year, RRR = number of

sensors on reel divided by 10 (200 for 2000 units), TTTTT =

Traceability Code.

Figure 14: Second label on reel: For Device Type and Part

Order Number (See Packaging Information on page 2), Delivery

Date (also Date Code) is date of packaging of sensors (DD =

day, MM = month, YYYY = year), CCCC = Sensirion order

number.

8.4

Shipping Package

SHT2x are provided in tape & reel shipment packaging,

sealed into antistatic ESD bags. For SHT20S standard

packaging sizes are 1500 and 5000 units per reel. Each

reel contains 440mm (55 pockets) header tape and

200mm (25 pockets) trailer tape.

The drawing of the packaging tapes with sensor

orientation is shown in Figure 15. The reels are provided in

sealed antistatic bags.

Header tape is to the right and trailer tape to the left on this
