(i)
Caution

See here for related information such as technical information on cleaning effects and other cleaned product lineups.
Cleaning also removes rust prevention oil, which may make the product more susceptible to rusting than an uncleaned product.
Please be careful about the application location and storage environment.
The spring constant and maximum angle used are indicated based on the value of the smaller wire diameter. Refer to the specification table for the correct specifications.

Product Description

Three types of cleaning methods are available: degreasing, precision cleaning, and electrolytic polishing + precision cleaning. They can be ordered from one piece with the standard part number.
This eliminates the need for customer cleaning or outsourced cleaning, reducing the amount of time and effort required.

■Part Number for Clean & Pack Products

·Degreasing (Anti-rust single packing)	: Part Number SL-□□
·Precision cleaning (Degassing double packing)	: Part Number SH-□□
·Electrolytic polishing + precision cleaning (Degassing double packing)	: Part Number SHD-□□

Product Part Number	Cleaning Method	Packaging Type	Effects Compared to Uncleaned Product	Environment (Standard)	Process
SL-□□	Degreasing	Anti-rust packing	Oil removal	General environment	Regular assembly process
					Post battery assembly process
SH-□□	Precision cleaning	Degassing double packing	Oil removal Dust removal	Clean environment (Class 10 to 1,000)	Battery assembly process
					LCD-related post assembly process
					In-vehicle camera assembly process
SHD-□□	Electrolytic polishing + precision cleaning	Degassing double packing	Oil removal Dust removal Outgas reduction	Vacuum environment Clean environment (Class 10 to 1,000)	Pre-semiconductor process
					Liquid crystal deposition process
					Pre-OLED process

■Notes
Cleaning also removes rust prevention oil, which may make the product more susceptible to rusting than an uncleaned product.
Please be careful about the application location and storage environment.

[Features]Arm angles of 90°/135°/180° are available for right and left winding.
