HE2B Enabling Switches

Multi-contact 3-position enabling switches

Ideal for installing in large teach pendants.

Features & Benefits

• Ergonomically-designed OFF-ON-OFF operation.
• Easy recognition of position 1 to 2 transition is made possible by a snap action switch.
• Sufficient difference in operating force is provided for shifting from position 2 to 3.
• Low pressure is required to maintain position 2, allowing for longtime operation.
• Reliable operation is assured even when the edge of the operator button is pressed.
• The switch does not turn ON while being released from position 3 (OFF) to position 1 (OFF) (IEC60204-1, 9.2.5.8).Some teach pendants are equipped with two 3-position enabling switches, and when one switch is ressed to position 3 (OFF), the other switch must not enable machine operation even when pressed to posi tion 2. Enabling of machine operation must resume after both switches are released. For this purpose, also available are 3-position enabling switches with monitoring switches for button returned to position 1 and button pressed to position 3 (monitor switches have direct opening action mechanism).
• Two contacts are provided in a 3-position enabling switch so that even if one contact fails due to welding or short-circuit, the other contact can disable machine operation.
• The waterproof rubber boot provides IP65 protection.

HE2G Grip Switches

Distinctive tactile feedback with 3 position 

Compact, light-weight grip style enabling switch provides a comfortable hold.

Features & Benefits 

• An HE2B enabling switch, compliant with IEC/EN60947-5-8, is installed.
• Equipped with different switches for various use. • Choice of wire-saving internal connectors or solder terminal connectors.
• The curved grip and small-size makes operation comfortable. The light-weight (approx. 140g, HE2G-21SH) and compact size is suitable for operators with small hands and for use in tight working environments.
• The operating force required to shift from position 1 (contact OFF) to position 2 (contact ON) is reduced by 50% compared with IDEC’s HE1G grip style enabling switch. Less operating force ensures worry-free operation.
• Tactile clicking feedback allows easy recognition of switch operation when shifting from position 1 (contact OFF) to position 2 (contact ON).
• Dual enabling contacts with a separate actuator for each contact is IDEC’s original design. This ensures a higher safety level. Disparity detection of category 4 (ISO 13849-1) can be achieved by using this switch with a safety relay module or a safety controller.

HE3B Enabling Switches

Rectangular operator part with φ16 mm mounting for easy installation.

2-contact 3-position enabling switches ideal for installing in small teach pendants.

Features & Benefits 

• Ergonomically-designed OFF-ON-OFF operation.
• Easy recognition of position 1 to 2 transition is made possible by a snap action switch.
• Sufficient difference in operating force is provided for shifting from position 2 to position 3.
• Low pressure is required to maintain in position 2 allowing for longtime operation.
• Reliable operation is assured even when the edge of the operator button is pressed.
• The switch does not turn ON while being released from position 3 (OFF) to position 1 (OFF) (IEC60204-1, 9.2.5.8).
• Two contacts are provided in a 3-position enabling switch so that even one contact fails due to welding or short-circuit, the other contact can disable machine operation.
• The waterproof rubber boot provides IP65 protection.
