IDEM Safety Interlock Switch, Keyed, Stainless Steel Housing, 690V AC, 25A Contact Current, M-ISP-SKR-25 (A101)

IDEM M-ISP-SKR-25 (A101) Safety Interlock Switch is a keyed, panel-mounted trapped key isolation switch constructed with stainless steel housing, designed primarily to ensure safe machine operation by enabling controlled access and isolation of safety circuits.

This safety interlock switch includes 1 normally open (NO) and 2 normally closed (NC) safety contacts, suitable for circuits requiring a contact AC voltage of up to 690 V and a switch contact current of 25 A. The device operates through a trapped key mechanism where the key is held when the machine safety contacts are closed and can only be released by energizing the internal solenoid, which enables safe machine shutdown before access.

The unit features a robust stainless steel 316 or die-cast metal mounting plate and barrel housing for enhanced durability in industrial environments. It includes a red lamp wired to indicate solenoid energization and a green lamp for user designation, along with a 2NC 1NO monitoring contact block to improve safety feedback.

The product complies with multiple safety and industrial standards including ISO 13849-1, EN62061, UL 508, EN60204-1, EN 1088, and IEC 60947-5-1, making it suitable for use in a variety of industrial, manufacturing, and automation applications where machine safety interlocking is critical.

Operating temperature is from -20°C to 40°C, making it adaptable to diverse environmental conditions. The switch dimensions of 112 mm length, 169 mm width, and 176 mm depth allow for compact panel installation.

Produced in the United Kingdom, this safety interlock switch is a reliable choice for industries needing secure, efficient isolation of machine safety circuits. It can be integrated with safety delay timers to permit machine run-down before key release, thereby enhancing operational safety.

Operates with keyed lock style for secure interlocking. Durable stainless steel housing construction. Supports 690V AC voltage and 25A contact current. Includes 1 NO and 2 NC safety contacts for reliable operation. Compliant with multiple international safety standards.

Operational temperature range of -20°C to 40°C. Compact dimensions for panel mounting. Visual indicator lamps for solenoid energized status. Trapped key mechanism to ensure machine safety. Manufactured in United Kingdom for quality assurance.

This IDEM safety interlock switch is ideal for industrial automation, manufacturing plants, and machine safety applications requiring secure interlock and control. Explore more Safety Interlock Switches and related components on EnvMart to find the perfect solution for your safety-critical systems.
