Choose Hirschmann when...

Your installation calls for a UL-listed connector, support for conductors up to 16 AWG or a cable outside diameter between 4.5 and 7 mm.

Choose HTP when...

You need a slightly shorter 30 mm housing, an IP67 protection rating or compatibility with cable outside diameters from 4 to 6 mm.

What These DIN Form B Specifications Mean

Cable Fit

Match the cable outside diameter to the connector's sealing range. Hirschmann accepts a slightly wider maximum diameter, while HTP starts at a smaller 4 mm diameter.

Environmental Protection

IP65 protects against dust and water jets. IP67 adds protection against temporary water immersion when the connector is correctly assembled with compatible sealing components.

Installation Compatibility

Contact spacing, base dimensions, and cable range should all be checked. A matching Form B profile alone does not guarantee compatibility with every valve or device.

Common Applications for Form B DIN Connectors

Hardwired DIN 43650 Form B connectors provide a removable electrical connection at compact industrial devices. They are frequently paired with solenoid-operated pneumatic or hydraulic valves, where the screw terminals simplify field wiring and the center screw holds the connector securely against vibration. The same format may also be used on compatible pressure switches, sensors, and other control components when the pin layout and cable entries match.

Form B Connector Selection Checklist

1. Confirm the format:
Form B with 11 mm contact spacing.
2. Measure the cable:
Check conductor gauge and outside diameter.
3. Check the environment:
Select the required IP protection level.
4. Verify approvals:
Confirm UL and application requirements.
