Basic Information

Compact, lightweight grip switches designed to fit comfortably in the hand

UL/C-UL,CE,TUV,UKCA Approved

Features

This product line includes models with control units suited to a variety of applications.

The compact, light weight grip profile was designed based on human engineering considerations.

The compact profile fits the hand perfectly, ensuring comfortable operation. Thanks to its light weight design (SG-C1-21: approx. 140 g) and compact size, it is easy to hold even for individuals with small hands, and it can also be used in confined work locations.

Reduced impact during extended operation

We reduced the impact during extended operation by lowering the holding load in position 2 (ON).

Pleasant, clear button operation

Tactile clicking feedback allows easy recognition of switch operation when shifting from position 1 (contact OFF) to position 2 (contact ON).

In order to avoid electric shock or fire, turn the power off before installation, removal, wire connection, maintenance, or inspection of the safety switch.
Do not disassemble or modify the grip switch.
When using the SG-C1 series for safety-related equipment in a control system, refer to the safety standards and regulations in each country and region depending on the application purpose of the actual machines and installations to make sure of correct operation. Also, perform risk assessment to make sure of safety before starting operation.
Do not tie the grip switch around the button with a tape or string to keep the switch in position 2. Doing so will prevent the grip switch from functioning as designed and is extremely dangerous. Systems that stop operation after the grip has been operated for a certain period of time and require the operator to grip it again are effective in preventing circumvention of the device's intended purpose.
Please note that permanent installation of the grip switch at the machine is inadmissible.

Use proper size wires to meet voltage and current requirements.
Do not apply an excessive shock to the SG-C1 series.
When wiring, prevent dust, water, or oil from entering the grip switch.
If used in wet locations, this device must be used with cable suitable for wet locations.
When multiple safety components are connected in series, the EN ISO 13849-1:2015 performance level will fall due to the deterioration in fault detection functionality.
The suitability of control systems in which this product has been embedded must be verified in accordance with EN ISO 13849-2:2012.
SG-C1 series is a device used for enabling a machine (robot, etc.) when teaching the machine in a hazardous area manually.
Configure the enabling system so that the machine can operate when the switch is in position 2 and an additional "start" is pushed to initiate the operation.
In order to ensure safety of the control system, connect each pair of the contacts of the 3 position enabling switch (terminal No. NO1-C1 and NO2-C2) to a discrepancy detection circuit such as a safety relay module.
(ISO13849-1:2015)
The base and the plastic part of rubber boot frame are made of glass-reinforced ABS / PBT. The rubber boot is made of silicone rubber. The screw is made of iron. When cleaning the SG-C1 series, use a detergent compatible with the materials.
As for momentary pushbutton switch and key selector switch of additional control unit, do not connect NO and NC contacts of a microswitch to different voltages or different power sources to prevent a dead short-circuit.
Do not operate key selector switch of additional control unit without completely insertion of the key.
The rubber boot may deteriorate depending on the operating environment and conditions.

Wiring Instruction

Wiring

Solder the terminal at 310 to 350 ℃ 590 to 662 ℉ within 3 seconds using a 60 W soldering iron.
Sn-Ag-Cu type is recommended when using lead free solder.
When soldering, do not touch the SG-C1-□ with the soldering iron. Also ensure that no tensile force is applied to the terminal.
Do not bend the terminal or apply excessive force to the terminal.
Use non-corrosive rosin flux.
Because the terminal spacing is narrow, use protective tubes or heat shrinkable tubes to avoid burning of wire coating or short circuit.
When using a stranded wire, make sure that adjoining terminals are not short-circuited with protruding core wires.
Use copper wire 60 to 75 ℃ 140 to 167 ℉ only. (UL508)
The wiring has to be installed according to GS-ET-22:2016, 4.2.6.

Recommended screw tightening torque

Part being secured	Screw position	Screw tightening torque
For mounting rubber boot frame on the base (M4 screw × 4)	A	1.1 to 1.3 N・ｍ
Cable gland to Grip switch Screw	B	2.7 to 3.3 N・ｍ
Cable gland to cable gland	C	2.7 to 3.3 N・ｍ

The B and C values in the above table reflect use of the recommended connectors listed above.
When using a cable gland other than the recommended model, check that part's tightening torque.
