HE1B Enabling Switches HE1B Basic Enabling Switch Key features: • 3-position functionality (OFF – ON –OFF) as required for manual robotic control • Ideally suited for use as enabling (aka “deadman”) switch on teach pendants • Provides a high level of safety based on human behavioral studies that determine personnel may squeeze OR let go when presented with a panic situation • Positive action contacts “On” (pos. 2) to “Off” (pos. 3) ensure no contact welding (per EN60947-5-1 / IEC60947-5-1) • Contacts will not close when released from “Off” (pos. 3) to “Off” (pos. 1) (per IEC60204-1; 9.2.5.8) • Small and lightweight Part Numbers Item Installation Part Number Side HE1B-M1 Front HE1B-M1N Specifications UL508 (UL recognized), CSA C22.2, No. 14 (c-UL recognized), Conforming to Standards IEC/EN 60947-5-1, IEC/EN 60947-5-8 (TÜV approval) Operating Temperature –25 to +60˚C (no freezing) Operating Humidity 45 to 85% RH (no condensation) Storage Temperature –40 to +80˚C (no freezing) Pollution Degree 2 Initial Contact Resistance 50mΩ maximum Insulation Resistance 100MΩ minimum Impulse Withstand Voltage 2.5kV Operating Frequency 1200 operations/hour Position 1 2 1: 1,000,000 operations minimum Mechanical Life Position 1 2 3 1: 100,000 operations minimum Electrical Life 100,000 operations minimum at rated load 2 Operating Extremes 150m/s (15G) Shock Resistance 2 Damage Limits 1000m/s (100G) Operating Extremes 5 to 55Hz, amplitude 0.5mm minimum Vibration Resistance Damage Limits 16.7Hz, amplitude 1.5mm minimum Terminal Solder Terminal 2 Recommended Wire Size 0.5mm maximum / 1 line (20AWG) Solder Heat Resistance 260°C / 3 seconds maximum Terminal Pulling Strength 20N minimum Recommended Screw Torque HE1B-M1: M3 screw / 0.5 to 0.8Nm Degree of Protection IP40 (IEC 60529) excluding terminal part Conditional Short-Circuit Current 50A (250V) Recommended Short Circuit Protection 250V, 10A fast blow fuse (IEC 60127-1) Circuit Opening Force 30N minimum (position 2 3) Control Resistance (Operating) 250N minimum Weight Approx. 6g 1705151129 www.IDEC.com 392 AS-Interface Safety at Work Light Curtains Safety Control Relays Enabling Switches Interlock Switches XW Series E-Stops Overview Overview XW Series E-Stops Interlock Switches Enabling Switches Safety Control Relays Light Curtains AS-Interface Safety at Work HE1B Enabling Switches Current Ratings Rated Insulation Voltage (Ui) AC / DC250V Thermal Current (lth) 5A Rated Operating Voltage (Ue) 30V 125V 250V Resistive Load (AC-12) – 3A 1.5A AC 50/60Hz Inductive Load (AC-15) – 1.5A 0.75A Rated Operating Current (le) Resistive Load (DC-12) 2A 0.4A 0.2A DC Inductive Load (DC-13) 1A 0.22A 0.1A Contact Configuration SPST-NO three position (OFF-ON-OFF) Minimum applicable load: AC/DC3V • 5mA (For reference only).
