• Two locking mechanisms to choose from—spring lock (unlocked with energized solenoid) or solenoid lock (locked with energized solenoid).
• M3 terminal screws for wiring.
• Wide operating temperature range (–20 to +55°C).

HS5D Interlock Switches

Head removal detection for safer performance 

Double insulation structure with 2 actuator entry slots. 

Features & Benefits 

• Head removal detection function turns OFF the main circuit (11-12) when the head of the HS5D is removed.
• The HS5D is the same size as 2 contact interlock switches (HS5B). 3 contact with dual enabling contacts and a monitor contact are available. Can be installed in narrow spaces. (30W × 30D × 91H mm)
• The actuator is interchangeable with HS5B and HS5E.
• Double insulation structure eliminates the need for grounding.
• The head orientation can be rotated, allowing 8 different actuator entries.
• Degree of protection (contacts): IP67 (IEC60529)
• NC contacts with direct opening action (IEC/EN60947-5-1)
• Proprietary actuators prevent invalidation of the contacts (ISO14119, EN1088).
• M3 terminal screws for easy wiring.
• Gold-plated contacts suitable for small loads.
