Filter Cap and Sockets

For SHT2x a filter cap SF2 will is available. It is designed

for fast response times and compact size. Please find the

datasheet on Sensirion’s web page.

For testing of SHT2x sensors sockets, such as from

Plastronics,

part

number

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 19.

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

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.

Figure 19 Laser marking on SHT20. For details see text.

Reels are also labeled, as displayed in Figure 20 and

Figure 21, and give additional traceability information.

Figure 20: 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 21: 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. Standard packaging sizes

are 1500 and 5000 units per reel. For SHT20, 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 22. The reels are provided in

sealed antistatic bags.

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

sketch.

9 Compatibility to SHT1x / 7x protocol

SHT2x sensors may be run by communicating with the

Sensirion specific communication protocol used for SHT1x

and SHT7x. In case such protocol is applied please refer

to the communication chapter of datasheet SHT1x or

SHT7x. Please note that reserved status bits of user

register must not be changed.

Please understand that with the SHT1x/7x communication

protocol only functions described in respective datasheets

can be used with the exception of the OTP Reload

function that is not set to default on SHT2x. As an
