1sna295427r1400 – in hd spacer

Why Choose the TE Connectivity 1SNA295427R1400 INHD1 Spacer?

The TE Connectivity 1SNA295427R1400, also identified as INHD1 or IN HD Spacer, is a 1.2 mm beige terminal block spacer designed for compatible Entrelec HD-series screw-clamp terminal assemblies. It provides controlled separation between adjacent components while maintaining the modular layout of the terminal strip.

Manufactured from polyamide, the INHD1 is designed for demanding industrial environments and has an operating temperature range of -55 to +110 °C. Its slim 1.2 mm width allows spacing to be introduced without unnecessarily increasing the overall size of the terminal assembly.

The spacer is compatible with several Entrelec HD terminal blocks, including HD10/12.F5, HD10/12.FF5, HD120/30.F10, HD185/36.F12, HD35/16.F6, HD4/10.F4.19 and HD4/9.F4. It supports standard TH35 rail arrangements as well as Type 2 mounting systems, making it a practical accessory for industrial and transportation electrical installations.

Reliable Spacing for HD-Series Terminal Assemblies

Terminal block spacers are used where additional physical separation is required between components while retaining the alignment of a modular terminal strip. At only 1.2 mm wide, the INHD1 introduces the required spacing with minimal impact on valuable DIN-rail space and provides an insulating polyamide barrier between neighbouring components.

The INHD1 is particularly useful with compatible Entrelec HD-series terminals and associated jumper arrangements. Its matched profile helps panel builders maintain a consistent assembly while its broad rail compatibility makes it suitable for a range of industrial control, machinery and transportation installations.

Typical Applications

• Spacing compatible Entrelec HD-series terminal blocks.
• Industrial electrical control panels.
• Stud and screw-clamp terminal assemblies.
• Machine-building electrical systems.
• Transportation and railway electrical equipment.
• DIN-rail power and control distribution systems.
