・All specifications are subject to change without notice.

(1) The output load line and input line shall be separated to

improve noise sensitivity.

(2) The sensing lines shall be twisted and separated from the

output lines for remote sensing.

(3) Use all lines as thick and short as possible to make lower

impedance, clamping core at both input and output wires

benefit EMI performance.

(4) Attaching a capacitor to the load terminals can eliminate noise.

(5) For safety and EMI considerations, connect terminal to the

mounting set ground terminal, power supply and load mount-

ing on aluminum plate is recommended for EMI setting.

(6) Recommended torque for the terminal :

SWS600L Input terminal (M4 screw)

: 1.27 N · m (13.0kgf · cm)

Output terminal (M5 screw)

: 2.5 N · m (25.5kgf · cm)

SWS1000L Input terminal (M4 screw)

: 1.27 N · m (13.0kgf · cm)

Output terminal (M8 bolt & nut) : 10.8 N · m (110kgf · cm)

(M4 screw)

: 1.27 N · m (13.0kgf · cm)

[The PHD connector manufacture method]

This product is using SPHD-001T-P0.5 or SPHD-002T-0.5 connec-

tor made from JAPAN SOLDERLESS TERMINAL MFG CO LTD.

Regarding to manufacture of a connector, it becomes the

regulation as following.

a). Appricable Wire and Crimping tool

Wire size is AWG#26 - AWG#22 and insulation outer dia is

φ1.0

-

φ1.5 mm.

Appreciable wire per barrel size is UL1007 (standard wire)

and its equivalent standard wire can be used. Regarding the

AWG#22, use UL1061 or its equivalent standard wire, because

wire insulation outer diameter of UL1061 is small.

Crimping tool is as below.

b). Crimping Operation

The reference value of wire strip is 2.3mm. As wire strip length dif-

fers depending on type of wire and crimping method, decide the

best wire strip length considering processing condition. When

wire is stripped, do not damage or cut off wire conductors.

Note1. Crimp height at wire barrel should be set to pre-determined

dimensions.

Note2. Adjust crimp height at wire insulation barrel to the extent

that wire insulation is slightly pressed, and set it so that

crimping is not excessivery.

Note3. Crimping condition at wire insulation barrel is as below Fig.1.

Note4. For AWG#28, #26, #24, use UL1007 type. For AWG#22,

use UL1061 type.

Check of crimping appearance visually for correct crimping as

referring to above Fig.2. Check the tensile strength at crimped

part when operation finishes.

c). Inserting contact into housing

Inserting crimped contact into housing

(1) Do not apply any pulling force to crimped part, and insert

contact parallel to housing.

(2) Insert contact into housing without stopping to innermost.

(3) Check secure locking per each insertion by pulling wire softly

in order to check that contact does not come off housing. Be-

sides, check whether there is the backlash in the direction of

insertion axis.

d). Mating and Unmating Connector

(1) Inserting connector

Hold receptacle housing securely and insert into header

straight against to header post until click sounds.

(2) Unmating connector

Hold all wires securely and fix receptacle housing by fin-

gers so as to pry, and then, withdraw it on the mating axis.

e). Routing of Wire

Routing wire so as not to apply external force to connector ex-

cept force to such an extent that wire slightly buckles, consider-

ing an enough length to route and fixing of wire.
